Brazilian Wandering Spider VS Funnel-web - WHICH is more DEADLY?
Вставка
- Опубліковано 24 лип 2024
- The South American wandering spiders from the genus Phoneutria, and the Australian funnel-webs from the family Atracidae. These constitute arguably the most notorious spiders worldwide, infamous not only within their native lands but across the globe, and people are none-too-slow to point at either of them as justification for the widespread and wildly disproportionate fear of spiders in our general populace.
But to what extent do these, widely regarded as the spider world’s heaviest hitters, live up to their fearsome reputations? Are they aggressive, lethal monsters? Or are they, like so many animals we fear, simply misunderstood, the unfortunate targets of endless internet hysteria? Let's find out.

Casually handling a huntsman on the bus is the most Aussie thing I’ve ever seen.
“These fat fuckers”
That caught me completely off-guard in this extremely well-researched and professional documentary, and I love it 😂
I do find swearing works best when it’s least expected haha
@@BugsandBiology also those fat fuckers they call fangs
Love it
I don't believe this is well research not one bit of it is true
@A1lwayright-tc5ot And your point is ? You should say nothing , and appear ignorant , than make a nothing statement like that , and remove all doubt. You are ignorant, That is what you just said about yourself, exit stage right . RARARA
As a Braziliian who have to deal with Wandering spiders inside home at the summers (also brown recluses), i can confirm they are big, very mobile and agressive and even a big one can hide in very, very small objects.
Edit: Wandering spiders can kill adults as brown recluse wich i also have to deal with. But local medicine use to be ready to treat if its called soon as you get bitten (same goes to snakes). Its all about reaction time vs poison spread time. This is why i think brown recluse its more risky due to be very small and not have a noticeable bite but yet take some days to actually kills. And i never killed a single one, just making them get in (or attack) a broom or i put a box over them and release in nature.
After learning about the Wandering Spiders my fear for Brazil increased and so did my concern for the people, must be scary going about your day yet that thing could be hiding literally inside/behind anything.
@@afanoflafear well those spiders appears because i live around a forest in Matadeiro Beach, so we deal with spiders and snakes. In a city environmentyou dont have to deal with.
See, that cements a comment I made on another video. I said that I find spiders to be absolutely amazing creatures but I appreciate them doing their job OUTSIDE of my home. 😂lmao 👍🏻 🙏🏻🙏🏻🙏🏻
@@LFREIF We have the Brown Recluse where I live as well. I wasn't aware that they've been around for years, so I definitely understand the concern about that species. They can cause necrosis, if I'm not mistaken, so I'm very careful now when near gardens and other known Recluse friendly areas. We also have the Yellow Sac spider, which can also cause severe reactions, and they are quite common and oddly a bit aggressive. I cannot imagine finding a 4-5 inch spider in my home. I think heart would skip a couple of beats.lmao😳🙏🏻🙏🏻🙏🏻
btw i never killed a single one of them, even had to deal with some snakes too. we can manage the situation without killing them.
"Funnel webs are extremely sedentary and reluctant to leave the safety of their burrows." - Spirit animal detected.
Tell that to the one thats in Jessica's shoe in Sydney!!
The males (most toxic) leave their homes in summer and wander around back yards, coming into houses and falling into pools. I encountered one on bedroom floor when I was staying at Merriwa Hunter valley, as I turned on light there it was giving the threat pose, the glass sliding door was open so it must have got in that way and as we slept on the lounge fold down sofa the spider was gone in the morning, thankfully that was the one and only time I've encountered one.
Fun thing is, dangerous spiders dont need to be venomous nor agressive. Huntsman has not much of venom nor do they bite often... But they do cause many car crashes and other accidents. My friend visited Australia and crashed rental car because when she opened sunscreen, large huntsman fell on her lap and run all over her. Not only was it jump scare but shes dead afraid even of small spiders...
Police was called by bypassers and they found her bout 800m from car, breathless and in panic close to insanity :) Car was tottaled, spider was found hiding under seat unharmed and she was ok if not count horriffic mental scar and 10x more of arachnophobia :)
Its hard to find statistic and specialy in fatal cases, theres no one to tell what happend. But in google, can find quite few accidents caused by spiders who otherwise are harmless. Theyr ability and likelyness to hide in unexpected places dont help theyr case, lol.
I like spiders, but still would have reacted the same way. No one wants a large spider to surprise them, especially while driving.
That reminds me of a scene from The Lost World, where a man was freaked out by a snake and in his panic got eaten by a T-Rex. 😌
No they don't that's an old wives tale just a urban legend lol 😆
Bro your story totally caught me off guard. What a nightmare and good telling. I will tell this story to friends to spook them. 😂
That sounds like a skill issue on the human's part. Just get rid of your arachnophobia 4head.
Why do I weirdly wish spiders were more dangerous than they actually are?
Me too 😂
I'm fine with how "dangerous" spiders are now. You're mad for wanting spiders to be more dangerous.
Love your style and the factual, clear presentation - missed your videos :)
I can't believe I was not notified of this video; I've been hanging out waiting for it. No matter, you've hit the mark again, Jackson. Keep 'em coming.
i absolutely love your videos and love you humor, extremely informative and brilliant.. please keep it up
Thanks! I’ll try to keep it up, but videos like this do take a lot of effort.
Love your videos. I'm not sure if your trying to be funny or not but I always get a chuckle listening to you
LOL. Another great video. You had me almost rolling on the floor in fits of laughter...almost. Job well-done mate!!
Almost? Well that’s not good enough, I’d better try harder next time!
Gotta say your art is stunning!
I very much appreciate this video on these two spiders that often get put on the same boat. Though I have a healthy amount of respect for both I feel like neither need to be feared as much as they are.
P. fera is one of my favourite spiders to see. They look weirdly soft, like they have teddy fur.
P.S. After watching you bathe your funnelweb with a brush I lost some amount of respect for em. They definitely put all their stat points in just 1 skill, huh? 😂
Yeah haha. Funnelwebs may have buffed up that venom, but dropped the ball on basically everything else.
Bro I was shocked at how slow funnel website were I thought they were fast like wandering spiders bit clearly not
@@blackeye3336 ikr. And they are no match vs a glass bowl 😂
Excellent video mate! Really well done!
Love your work mate, keep it up!
This was great! I very much enjoyed it. Thank you.
I have a BWS preserved in formalin that I captured about 30 yrs ago. It came in with a shipment of bananas at a local Phx grocery store. My wife contacted me immediately because she knew that I was a spider buff. I didn't recognize the species at first. It was VERY aggressive and attempted to bite me thru the plastic cake container it was captured in. Unfortunately, it passed after about a week. I'm glad that I kept it as my sons both would take it to show and tell at school. They were the cool kids because they had a specimen of one of the most venomous creatures on Earth. As cool as it is, I'll stick to tarantulas. As for which is more deadly ? Both have very potent venoms, but the BWS takes the prize, BUT, because of the proximity to humans, the Atrax species typically gets more bites in.
Just curious, what year was this?
@@alohafromthe3033 1994
That's why they are called Banana Spiders.. i know a lot of stories from German supermarkets where they came in banana boxes..
damn wish i was notified of this video, the bell icon is clicked?? anyway awesome informative video dude. youre really funny yet very professional and knowledgeable. keep up the fantastic content mate :)
One thing you overlooked was the size of their laughing gear and the way it is angled. Lived in Sydney as a kid and a friend got tagged by a Funnel-web straight through her toe nail, ended up in hospital of course but she lived. Never was an arachnophobe, but we had trapdoors in the lawn and the occasional funnel-web wander into the house, treated them with the respect they were due.
People are instantly afraid and thus demonize that which is alien to them; instead of understanding, or at least giving their best effort, they choose to hate. Sometimes I get sick when I think of how much power we possess and how little we have evolved. God forbid we ever meet an off world civilization, I fear for them not us!
Facts
The insta-fear response is an evolutionary advantage that keeps us safe. The second response once safe, agreed, should be curiosity.
@@kausha7135 Theirs a difference between fear and phobia. Fear is a natural emotion. Phobias are irrational fears born out of trauma and an unwillingness to overcome it. Those with phobias are to be treated as weaklings until they overcome said phobias.
@@kausha7135 And the weak serve two purposes in life. To become successful or to die for failing to become successful. Only those who are mentally and/or physically strong have a right to live in this world.
@@kausha7135 Everyone else is fodder until proven otherwise through becoming strong. Losers are not tolerated in nature. Without our intelligence and technology, humans are useless and expendable freaks of nature.
A confrontation between a wandering spider versus a funnel-web would be interesting but probably cruel because both species would never ever meet in real life. I'd like to include the even more enigmatic six-eyed sand spider, but they rarely move too much yet they're extremely agile as hell...So interesting this.
I appreciate that there are so many people like you can teach how amazing spiders are. In fact while my favorite species is still the zebra jumping spider funnel webs come close. I'd still not get close to one but they're an impressive and badass species. Wandering spiders on the other hand have beautiful colors.
Go watch some Peacock Spider videos. You’re welcome. 😊
Nice video. Personally, though, I think when most people talk about how dangerous something is, the encounter is assumed to have happened. There's a difference between "X species is this dangerous to the human species," and "An encounter with X is this dangerous to the individual encountering it." Mosquitos kill far more humans than polar bears, but everyone would call the polar bear more dangerous to actually encounter than a mosquito. If I run into a polar bear, I'm not going to be like, "Oh, this is rare, so I'm not in much danger."
But I agree that general disposition and likelihood of dry bites and whatnot are part of the common danger equation.
The BWS is more likely to dry bite then the Funnel Webs are.
Yeah there’s definitely an air of subjectivity to it, which is why I tried to clarify that this was my metric for determining danger, and not an objective standard.
@Bugs and Biology Its also one of the problems people dont know...they only look at toxicity of the venom...instead of the spider's willingness to use that venom which, as you believe, same as me, (i think) is the most important factor.
well its not even the Mosquitoe, its the potential that they could carry plasmodium falciparum or vivax or other potentially annoying to leathal protists, bacteria or viruses.
maybe also the question of how fast that damage would occur, how direct. how initilly painful, how used we are to being around the potential danger, how easy it is to avoid etc
Just imagine how deadly they would be combined.🕷️
Might end up being worse if you combined the funnel-web’s terrible mobility with the wandering spider’s low envenomation rate.
A man can handle a bite from either spider it doesn't even hurt that bad the only people who need to be worried are the elderly and sickly people so there you go no worries
Maybe less so, like imagine a Brazilian wandering spider who doesn't wander.
I love your videos thank you for uploading.
Love how this video starts with you free handling an Holconia immanis
I thoroughly enjoyed this video and seeing some actual well-researched information for once. Could you also do one for the Brown Recluse? There seems to be much debate about the severity of the wounds their bites can inflict, more specifically if they can cause necrosis and lead to amputations or not. Some argue it's mostly misattributions or bacterial infections that are responsible.
I greatly appreciate how informative and also how hilarious your videos are 🙂 You always manage to crack me up with your commentaries..."That's like having 8 brains and being a creationist." You're definitely a natural at these videos. You can tell you're really passionate about Bugs and Biology. Your genuine desire to share the proper knowledge and information really comes across to us. Thanks for sharing and keep up the beautiful work, brother 🙏
Thanks! Somehow I knew the creationist line would be one of the more “quotable” statements in this video. Had a few comments about it.
The vennum from a funnelweb spider is stronger .
Best thing about both spiders is they live about as far from Britain as you can get
why would anyone let a spider with seriously medically significant venom, climb on their hand and arm? The video poster might think this is a show of bravado and courage but I think its plain dumb. Apart from that, a great video overall. Well presented and explained.
It’s not about bravado, it’s about showing that even very defensive spiders don’t just bite willy-nilly unless already aggravated.
👍 an excellent video with a rather fine last line...
It makes you wonder how on earth these animals get their fearsome reputations. Yet no one blinks an eye at things like mosquito bites. That cause an estimated 7/800,000 deaths per year.
Well to be fair it’s a lot less pleasant to be bitten by one of these than a mosquito
I agree that death sound more severe than the other side effects of the Brazilian Spider, but I would still call it a tie race.
They are harmless
You have created a knowledge and care.
great video. about time someone did a sensible video about the danger hype surrounding these types of spiders. the guy with the spider on the bus....was that a huntsman spider ?
Yeah, that was me with the boys I coach on the way to a race. I often bring spiders etc. with me; the kids love handling them.
I wonder how often either species tend to deliver dry bites in comparison. Not sure how true but I do believe people online tend to state that funnel webs rarely dry bite, which might account for the number of confirmed wandering spider bites with little to no symptoms.
Plus the funnel webs bite more than once!😮
@@marciasmith6993 not only that, but it’s fangs are so long that they’ll often hook in if they land a good hit on you.
@@builttoscalevideos I suppose that makes sense since they are supposed to be used to hold on to food and not let it go till its done eating. Dowside: They do not intend on eating your hand
I forget the source, but it was claimed that funnel web - and I suppose the same applies to most myglomorph - spiders have a poor venom delivery system.
And so it may not be an intentional "dry bite", but more that the spider doesn't achieve the penetration necessary to deliver a full envenomation.
Obviously the spider has the equipment with those large fangs, but the spider's aim is to defend itself and not get stuck in it's perceived threat, where it can be splatted like the proverbial bug it is.
I can't remember where I read the article(possibly reddit?), but I remember the statistic for phoneutria bites being people receive a dry bite in around 95% of all cases.
I totally agree that these spyders are not deadly as expected. I personally have met Brazilian Wondering Spiders many times. Althouth they are quite agressive if they think you can pose a thread. They will be ok if you learn to respect their space. There are just some cautions you need to take care if you live close to them.
I'm curious...how deadly would a FULL ENVENOMATION bite from a Hadronyche Formidabilis (Northern Tree-Dwelling Funnel Web Spider) be with no access to anti-venom for an adult human?
possibly death
@@mesutdoyurucu377What could the cause of death be in such a case?
Respiratory failure?
Kidney failure?
Fatal haemorrhage?
excruciating pain like a molten hot knife twisting inside you leading profuse bleeding out of all orofices leading to insanity and death by suicide.
While you wouldn’t die, obviously, the venom would cause adverse effects to your nervous system, just like any other venom. Everyone reacts differently to one another, but you’d likely just have some nausea, sweating, slight breathing issues, and fatigue.
The bite area would likely be swollen and have some muscle issues for a few hours, while your body tries to fight off the venom’s effects.
Much like with snake bites, it’s not the bite that’s a problem, or even the venom, but WHERE you are at, when you’re bitten. If you’re miles deep in the wild, in ludicrous heat and nowhere near shelter, pushing yourself with the venom affecting your system is a bad idea, period - dehydration could lead to disorientation (getting lost on top of that), and an irregular heart rate could lead to heat stroke, or breathing issues.
Like I said, you’re not going to die, unless you get stubborn and try to push yourself. The best you can do is try to find a place where you’ll be safe, out of the heat, and with some access to water. Lie down, drink water, and keep your heart rate low.
You’d want to rest for a few hours, possibly a day to be safe, just taking it easy, and not spiking your heart rate or getting dehydrated. You’d also want to make sure to keep the bite area clean, to avoid infection, and if you had it, take some anti inflammatory medicine. I wouldn’t recommend dipping the bite area into a stream or lake, unless the bite area had TOTALLY sealed itself shut, to avoid infection.
I’m not a doctor, though, just someone with wilderness experience, and happens to love snakes and spiders.
I want to know that for the Funnel-web and Brazilian Wandering Spider as well lol
i love that style of music. cool to see you do too.
Just curious. In regards to the funnel web, I recall reading that one of the reasons the fatality rate of the spider wasn't terribly high, was because the spider tended to deliver a dry bite, using the size of its fangs and the sharp pain of penetration. That always made sense to me, as why waste precious venom on something you can't eat - we've even seen this with your centipede. But you're far more knowledgeable about this then I am, so what are your thoughts on that?
That's pretty much correct, as far as we can understand it. They know that eating you isn't an option and won't waste their venom easily, if that's the case. But it's nothing you can depend on in any capacity. It's still "being lucky" if you get a dry bite, even though some species are somewhat more likely to dry bite than others.
Even a full bite is unlikely to kill someone in Sydney as they have anti-venom readily available in hospitals e.t.c so as long as you get there you'll be fine.
That's an incredible observation. I have to be honest. This is one of the most intelligent threads I've been involved with for quite some time. Thank you ALL, for a fantastic experience. Lol
Good video! I liked your take on 'poisonous' and 'dangerous'. Aren't Funnels an old species with no cardio and bad eyesight?
Awesome upload
Well as a health professional (ICU nurse), I’ve been passionate about all venomous critters for close to 40 years. Read numerous papers and studies mostly on scorpions, spiders and snakes. I used to breed several highly venomous species among which Latrodectus mactans (spiders) and several hundreds of different medically significant scorpions that I used to ship to different scientists worldwide.
Anyway, birth of both my children put a stop to this crazy hobby but while my passion subsided, my interest about venoms always remains. Still have vials of the Mexican Alacramyn antivenom at home as memories of the good old days for God’s sake !!! 😂
Here were my main medically significant scorpion species (used to work in Mexico and would go on scorpion “hunting”):
- Centruroides infamatus (from Michoacan, Mexico)
- Centruroides limpidus/tecomanus (from Colima, Mexico)
- Centruroides noxius (from Nayarit, Mexico)
- Centruroides elegans (from Jalisco/Colima/Nayarit, Mexico)
- Centruroides suffusus (from Durango, Mexico)
- Androctonus australis
- Androctonus crassicauda
- Androctonus amoreuxi
- Androctonus bicolor
- Leiurus quinquestriatus
- Parabuthus granulatus
- Parabuthus transvaalicus
And tens of other lesser medically important Buthidae and other sp.
Anyway, back to the main topic of the video, all in all there’s dangerousness as far as possibilities of getting bitten/sting (likelihood) and then potential severe envenimation IF you ever get bitten/stung.
That’s the difference between potential overall danger/risk and potential lethality (as it is zero if you don’t get bitten/stung, of course).
True that you can have dry bites or never ever encounter a critter by either one on these species BUT if one would receive a full bite with full envenimation , there seems to be little doubt that the aforementioned Southern and Northern tree funnel web species (Hadronyche cereberea and H.formidablis) would bring the most severe symptoms compare to Phoneutria fera or P.nigriventer despite their higher incident frequencies.
Of course, access to competent medically facilities and/or antivenom (when needed) could change the picture/outcome in some cases.
Interesting also to note that some compounds of the funnel web spiders’ venoms are particularly toxic to primates/humans while having little effect on cats and dogs which in turn can get highly envenomated by some other Australian mygalomorph spiders (harmless to us).
Anyway, I think that what most folks want to know is the potential danger/legality if you happen to get bitten. And for humans, as far as spiders go, I think certain funnel web sp. take the cake with higher risks of severe envenomation.
Keep up the good work, very interesting video btw.
Regards
Thanks, glad you enjoyed. That's an amazing assortment of scorpions! I'd love to film more videos about scorpions someday, but the only ones I regularly find locally are Hormurus, which aren't the most exciting critters, though they do serve as great examples of how passive many species are.
This is the video the world has been waiting for!
Finally someone who really debunks those urban myths. I also hate all the clickbait crap on YT concerning venomous animals, so thanks for being one of the few out there, who clearly know what they are talking about and bust all the other shit.
Appreciate it! The amount of sensationalism out there is honestly overwhelming.
I love your work.
adjust the amount of venom depending on the size of the prey or predator. At certain times, they do not inject venom when biting, hence called dry bites. When hunting, they do not rely on their vision, but their vibrations. They have unique warning sign, where they lift their front legs and swing back and forth before the attack.
What is the difference between Sydney Funnel-Web Spider and Brazilian Wandering Spider?
• Sydney funnel-web spiders are only found in the areas, in the city of Sydney, Australia, whereas Brazilian wandering spiders are found in Central and South America.
• Sydney funnel-web spiders are normally larger than Brazilian wandering spiders.
• Sydney funnel-web spiders are black with hairy smooth bodies, whereas Brazilian wandering spiders are brown in color with red hairs on their body.
• Brazilian wandering spiders are more aggressive than Sydney funnel-web spiders.
• Unlike Brazilian wandering spider, which delivers occasional dry bites (without venom), Sydney funnel-web spiders always deliver bites with venom.
• The scientific name of Sydney funnel-web spider is Atrax robustus while that of Brazilian wandering spider is Phoneutria fera.
• Unlike the Brazilian wandering spiders, Sydney funnel-web spiders build funnel web to live.
• Venom of Brazilian wandering spiders contains Phoneutria nigriventer toxin-3 (PhTx3) as the main compound whereas, that of Sydney funnel-web spider is atraxotoxin.
Hope this helps❤
i liked b4 i watched because i knew i would like it (and had to be 1st muhaha), i watched it right after and did not disappoint, like always. Great video.
love your videos
Finally. I found the bug channel I've been looking for.
Haha, hope you enjoy your stay!
I've got two Thailand funnel-web do you know any information on them because there's not much information out there
Unfortunately not, sorry.
As someone who is creating a Graphic Novel about spiders - Thank you so much for this video! It helped reassure me that I am making the right decision with how I handle these two spiders as characters in my book. 😁
Thanks! Glad my video was able to help!
@@BugsandBiology No problem! I enjoyed it very much.
Loving your paleo ref x
That Huntsman at the beginning is gorgeous. I love those gentle giants! Still wouldn't hold one like that without suffering a heart attack
Thank you for a well-researched and rationally presented video. There needs to be more of this sort of stuff on YT to counter the preponderance of sensationalist nonsense. Also respect to your calm and well-argued takedowns of idiots in the comment section. Great channel, to which this tarantula-owning Brit is now going to subscribe (and I don't subscribe often to channels).
I loved the last disclaimer about the comments :)
And a couple people were more than willing to oblige it seems…
You also did not mention that the Brazilian wandering spider doesn't use its venom unless it is in a life-threatening situation. The first bite for Brazilian watering spider is always a warning by. If you press the spider even more, that's when it will use its venom and cause the most damage
This is false, in some cases that might be true but sometimes it will use it’s venom immediatly if threatened.
@@Ryebob69 wrong. They don't inject all the venom, only a small fraction since the male will gonna keep looking for the mating after.
@@andrereis7993I've seen accounts of Brazilians who've been bitten with full venom just once by sticking their hand say in a cabinet for example. They describe a single bite that resulted in severe symptoms and required anti-venom to survive. Recovery in most cases took weeks to years.
@@thelastofthemachines Totally wrong. There's 18 fatal cases registered and a lot of others underreported before the development of the antivenom.
@@andrereis7993 How does this offhanded comment defend your argument? 🤦♀️
I have seen a video of a wandering spider being aggressive, not just defensive. It was a guy holding out a thong (sandle) with his girlfriend screaming in the background. The spider ran approximately 2 feet towards the Sandle and layed in a bite. It was an attack. Not a defense. Call it a defensive attack if you will. As an Australian, i havent seen a male funnel web do this. Ive only seen it once, but that wandering soider was angry, very angry. In saying that, i imagine the toxicity of the funnel web is more potent. The chance of a bite from a wandering spider seems more likely from my fascination with these things.
Thank you for your assessment of these two genera. I appreciate the absence of sensationalism.
It’s a shame that nearly everything online about these spiders is sensationalised.
would you compare these to Six-eyed sandspider which is surrounded by some myths.
Hey man as a massive fan of your work and a high admiration of your skillset and knowledge of the undergrowth I thought I would bring this to your attention their is a channel out their named Animal Secrets and its no secret the mishandle and outright abuse their animals, id just like your opinion on this matter. Thanks in advance
I’ll take a look, thanks
There not their X 3
I heard some people have a similar debate on which scorpion species is deadlier, death stalker or indian red. Some say fat tails or thick tails are deadlier.
Awesome vid as always mate, on another subject can U inform us on this new species of trapdoor spider that was found in Qld. !! The other day thx..👍 when possible
Definitely something I may make a video about
Have kept BWS; very large, nervous, vary fast, and can climb glass. I would be much more concerned if it got loose in the house versus any of the funnel webs.
I believe at 2:40 you can see the funnel web's heart beating, incredible detail.
I noticed that too! Really cool
You’ll notice that with a lot of spiders
Ew, it's like a single throbbing testicle in a diminutive, babyish nutsack. You are, of course, most welcome.
Thank you for eliminating much of the sensational fanfare given to these 2 families however much fun it probably is to imagine the result of dangerous encounters one might run into in the unlikely event of even being on the same continent with one or another of these much maligned creatures.
i will always love spiders bc they are free pest control just like other insects such as centipedes, scorpions, wasps, hornets, mantids, assassin bugs and these are insects i do not kill if they arent bothering me i even get a catch cup for wasp and hornets freeze em for a few minutes and release them outside
Do Wandering Spiders have one or two pairs of book lungs? Don't the less basal types with inward facing fangs, have two pairs? versus the downward facing, single book lung, older clades, like funnel webs belong to. Also, wouldn't it be a lot easier for the downward fangs or a Funnel Web to bite you quickly, versus the sideways type the Brazilian has? Cos it would be harder to get some deep skin, in a pinching motion, versus a deep downwards puncture. The amount of venom pumped in would be affected by this too, surely? Trying to remember the arachnid part from my biology degree. Cheers
You are correct, yes
A bite from a spider doesn't guarantee being receiving venomated. Sometimes a bite is just that, a bite.
And this video was focused on the overall danger these spiders pose, to which dry biting is a very relevant factor. I focused on overall bite severity as opposed to venom potency alone for that very reason.
I LOVE UR VIDEOS !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Finally, someone who appears to have some idea of what they're talking about. This bloke has submitted his review based on scientific data, NOT personal opinion.
There's a perfect flipside example to the inland taipan too.
The saw-scaled viper is often considered one of, if not THE deadliest snake in the world. However, its venom is (relatively) mild, at least compared to other deadly snakes. What makes them dangerous is that they're tiny, very aggressive and quick to bite, like to hide out in human settlements, and well... their venom is still deadly enough to kill many people and send many, many more to the hospital.
Yeah for sure. Probably could’ve mentioned that, but didn’t want to go on too much of a tangent.
@@BugsandBiology Yeah understandable. Great video though, I learned a lot!
Brazilian wandering spider-More potent venom but injects venom in much smaller quantities due to their smaller fangs
Sydney funnel web spider-Less potent venom but injects much more venom due to their larger fangs
Most big spiders stand up when feel threatened they do that to make the other feel threatened it's called threat posture and I may be wrong but I'm pretty sure there are only a few big spiders that don't do it
i think they are both dangerous for there own reasons the funnel web venom is more powerful and can kill you but you are more likely to see the wandering spider and they can see and have better mobility for me its a tie
20:20 Interestingly, it means that the severe envenomation rates of these 2, and especially H. formidabilis, are likely on healthy adults.
Yeah definitely. It’s a good thing those tree-dwellers have out of the way distributions; they seem pretty gnarly.
Watching this now because I just found out I took a photo of a wandering spider when I was travelling
Since they have large fangs and gulp down on pray that have been around multiple landscapes with lots of bacteria and dirt, wouldn’t infection from a bite rather than envenomation be more medically significant? As they view us as predators and don’t want to waste their venom on something they can’t regularly take down and eat for dinner.
I wouldn’t say so. Plenty of other spiders live very similar lifestyles but have only rather mild bites.
Apparently it’s just an unfortunate coincidence that Atracid venom happens to have major negative effects on primates.
@@BugsandBiology Oh alright, thanks for the info. Keep up the good work.
I'm going to put my money on misunderstood. I think if you go out of your way to piss off a spider you're going to get inoculated.
Case in point, the 6 eyed sand spider has powerful venom but they don't go around making statistics out of people.
What about Latrodectus mactans? Are black widows not in the same realm of deadliness?
"That would be like having 8 brains and being a Creationist." Says the human mammal who was clearly created from a significantly intelligent being.
I was indeed created by an intelligent being. Mum is very smart.
Loxosceles Laeta has a high death rate across South America.
Yeah I’ve heard. As underrated as these two are overrated.
@@BugsandBiologyI agree, there's another species of spider that's very underrated in my opinion: Mouse Spiders (Missulena).
Watch this video if you want A) A well researched and non-sensationalized review of two demonized types of spiders, and/or B) To watch funnel webs get verbally roasted for twenty minutes. Great video.
Haha, thanks. Gotta keep a balance between academic info and fat-shaming spiders.
@@BugsandBiology Still enjoy your videos - and 'they can't climb for shit' 'oh shit'
When that one climbed out of its container lol
“That’s like having 8 brains and being a creationist”
[INCOHERENT COMMENT IN ALL CAPS FOR YOUR AMUSEMENT]
I remember that you guys lost a poor young man back to a redback spider in 2016. I'm sorry for your lost guys.
As soon as you find out there's a funnel web spider is under ur bed u won't be able to sleep believe it.
They can barely climb, and none except mature males will even venture from their homes unless forced out.
The Fraser Island funnel-web is currently considered the same species (Hadronyche infensa) as the so-called Toowoomba funnel-web or long toothed funnel web, However, due to millennia of isolation, the Fraser Island funnel-web is genetically different. It's venom has been recorded as being six times more powerful than the Sydney funnel web spider. 🕷🕷🕷
Comparing blind spiders to creationists is hillarious, never change
My grandfather told me of an incident when he was young and took a job in produce section on a grocery store. They were unloading a shipment of bananas when a large spider ran out out of three bananas and big his country worker on the finger. The fellow immediately ran over and grabbed a cleaver and chopped his own finger off. I was always puzzled by this until I found out about the BWS. Now I get it.
You mate, are as entertaining as a humble animal educator can get. Comparing the poor vision of a funnel web with the 8 brains of a nonexistent intelligent intelligent designer left me howling. And I'm not a werewolf! This hotel of facts rates ✴✴✴✴✴, and a new subscriber.
Much appreciated!
Predictably, that line did stir the pot a little…
@@BugsandBiologyPlease, keep the pot swirling. I've discovered very few snarky UA-camrs. And IMO the demented world we live in demands snarky sarcasm. "Just Some Geezer", comes to mind. If you know of others please share. Thanks! ¯\_(ツ)_/¯
And was totally unnecessary. I am a bible believing God honouring man. It is no wonder to me that He'll has enough room for all the unbelievers. Even you sir.@@BugsandBiology
Bro handles spiders on the bus 😂 👍
And at work. And my friend’s birthday party last night. And on the train. The list goes on haha
Usually these types of videos cause a lot of weirdoes to come crawling into the comment section but it's been eerily calm so far...
There is one guy who got a little upset about my jab at creationists.
But I’d say the reason there aren’t many weird comments is cause the video is new, so most of the views would be from my subscribers.
Now we're asking the real questions
IN THE 2ND TAIPAN TIC IT HAS A PIC
Hi. I am from Greece, and I have seen small funnel - webs in my home town....
They would be a related, or similar spider, but definitely not the same.
When talking venomous bites aggression would play a major factor if one is really venomous but has a dry bite when not threatened or has too small of fangs to even get the venomous in the bloodstream that venomousness does nothing to make it dangerous to humans. Just like a bitter that bites repeatedly injecting venom could be more dangerous than one that bites once and scurries away
Love it when you roast tf out of funnel webs
They're awesome inside of their world. They just absolutely suck in the human world.
That same "Australian" funnel web spider is right here in the Caribbean
Very much doubt it. There’s a lot of black Mygalomorph spiders that bear a superficial resemblance to Atracidae.
@@BugsandBiology have you been here in the Caribbean? That same spider is on the island where i live. It makes the same trap door and everything
There’s a lot of spiders that construct similar homesites to funnel-webs. Mygalomorphs as a whole aren’t the most diverse bunch in terms of lifestyle.
@@BugsandBiology i don't know man they just look alike but a bit smaller
I wish people would leave the poor widows alone
I just feel sorry for their undeserved bad reputation lol. In the us people are so dramatic and we have three species of them 😂
Huntsman spiders look creepy with their Dhalsim legs
