Key terms mentioned in this video:
Annelids
Segmentation
Arthropods
Coelem
Cephalothorax
Crustacea
Insect (Population compared to other organisms)
Summary of this video:
While humans and chordates may be pretty complex species, we could not have been so mighty without insects. On a side note, insects topple all other organisms combined. That being said, we must learn about these insects to get a better understanding of ourselves.
Across the Disciplines:
Angiosperms ("flowering plants") required the use of insects to evolve.
Nice
"and mites, they don't bother you at all..... they might..." I died
XD me too
and his little smile when he said it xD
I shouted like: 'ayy!'
It's at 6:51 if anyone was wondering
you died you meen did
"I love me catepillar" - Hank Green 2012 12:33
I love my caterpillar
"and tell me what you think we should name this one! thats all. bye" i nearly started crying
i want a catupiler
Andi Yuan For anyone interested, I think that’s a Hornworm he has in the video, it’s a squishy green larval form of a hawkmoth used as a feeder insect in the reptile trade
I think I can sum most of my fears up into one word: "arthropods."
+Cheyenne Marie Oh don't be such a spoiled sport! Arthropods are amazing and fascinating! And they probably help the environment more than you probably realize. So in a way they are helping us human being get by.
+Lauryn Sawyer don't be mean, or a spoil sport
cosette mac lean
I wasn't being mean. In fact I was trying to open her eyes. You can't hear the tone in which I'm speaking otherwise you would know that I'm trying to help her. Trust me, most people are mean to me for plenty of reasons so I try as hard as I can to be nice.
girl, i am not trying to battle with you! simmer down!
+Lauryn Sawyer Holy shit, she's joking.
Watching this for review and I realized my professor basically stole this whole video word for word for his lecture...
+skippinginthesky And they punish us for plagiarism.
The fact that they plagiarize does not justify plagiarism.
Draganko123 Yes, I know. They should be setting an example, though.
And to think you payed what like 40K? to sit in a lecture hall listening to a regurgitation of free and open knowledge.
Busted.
I feel I need to personally thank you Hank for these videos. I know they are mostly for biology students and such, but I make my kids watch them. They are 7, 6, 4, and 2, and the LOVE them. A few days after watching this video my husband and I went out and left the kids with a sitter. Imagine her surprise when my 2 year old made a worm out of blocks, pointed to it and told her "Look it's segmented!" Your crash course videos are making my homeschooling even more effective! Thank you!
Thankfully, Hank decided to not show us these graceful leeches up close by displaying them on his hand.
The earthworm is trying to scream "help me, i've' been abducted by an insane giant monstrosity!"
I used to think spiders were creepy, too...UNTIL I REALIZED HOW AMAZING IT IS TO WEAVE A TRAP FOR YOUR PREY OUT OF YOUR BUTT! Seriously, I mean what kind of crazy evolution is this?! Butt nets! Well played, spiders.
And they rebuild them really quickly. Busy little critters.
pff anything can shoot guts out of its anus if it tries hard enough (granted it has guts)
@patrick Chen anyone can do that by going to Taco Bell.
Adler's upload area Unkile a sponge
XD
I find it funny how in my culture people despise insects and say that people who eat them are dirty and gross. Yet everyone here likes to eat shrimps, crabs and lobsters…
Everything should be okay, as long as the animal eaten is treated well before consumption and as long as if it's edible (obviously).
An animal's cuteness or beauty should not be a reason not to consume it. Though I can see why eating a butterfly could be nonsensical. But in some regions people eat grasshoppers though. And where I live we eat lots of cute cows, goats, pigs and birds. I find it silly when people say they don't like it when beautiful animals are eaten, as if it were only okay when an animal is "ugly".
Also I doubt a butterfly is beautiful for a reason. After all beauty is a human concept and not an inherent quality created by nature.
Insects and crustaceans are different though.
@@garrusn7702 how so?
AlphaPlantMom They’re from completely different phylogenetic groups. Both Arthropods. . .but still, not the same group of animals.
@@garrusn7702 yes I know that, I was just wondering why you, or if you differentiate between them as food and not food
the rhinoceros beetle was so faking cute lmao
and dude, I want that caterpillar at the end lmfao
They looked so cuddly.
Watching this for my finals 👍🏽
Same 😂
This is a hard video to watch when you have multiple creepy crawly phobias. But it's worth it. I MUST LEARN!
I knew I didn't play Animal Crossing for nothing.
OH GOD THE WIGGLE ON THE PUPA
They mite. Mite.
...Mite.
I think I'm in love with Hank.
facepalm
Jeff. It should totally be Jeff. In the future, you name everyone Jeff.
Also that rhinoceros beetle was totally adorable! (And so was the pupa until it moved...I didn't expect it to move. But then it was cool again!) Good episode. xD
SamuraiMatt He should name ot Eggbert to be ironic.
Thank you so much for these videos! It is such a fun, new way to study and review material.
the creatures in his hands are so beautiful!!!
great job at distributing so much information in such short time- very helpful
12:33
This absolutely made my day!
Oh Hank... I love you so much. xD
pretty spot on, but, in partial metamorphosis often a key difference between adults and nymphs is that the nymphs always lacks wings, while the adults may have them (although in some cases the wings are not suited for flight.)
Examples include mantids, stick and leaf insects, and cicadas, to name a few. So, the difference between partially metamorphosing nymphs and adults is not just limited to size.
These videos are seriously teaching me/helping me study for finals way more than my professor has all semester. And what's even better? Hank Green doing it. THANK YOU.
Sir that was the most amazing explanation the world could ever have. Thanks
My favorite line in this one is: "So insects, basically wizards, but not as delicious as crustacea, the insects of the sea." Only someone as awesome as Hank could make a segway like that! Or should I say a SEGMENT like that!
"this is the rhinoceros beetle pupae..........which is exceptionally creepy" *laughs kinda creepily but also enjoying the creepy bug*
I've been waiting for this one. Excitedly waiting.
6:41
Mites... witch don't bother you at all... well probably... they mite. *grins*
Eli Chamley which**
Nominated for grossest crash course video...thumbs up if you agree.
I love this series you guys rock! Teach way better than my bio professor.
A Fuentes I agree
this video is my favorite. Laughed a lot while still learning, loved it!
This was my favourite Biolography so far.
Crash course physics!!
One day, there shall be physics ! But not yet
gnhtd1 Awww! But I want it *now!*
btw it's been going for almost a year and it's awesome
6:52 did he just... The puns are so strong
Sarah Starr Yes, the puns are strong with this one.
All Mite>PLUS ULTRAAAA!
The pun was al mite y
@@deuzvoltz2804 PLUS ULTRAAAAA! my hero academia??!!!
Sarah Starr aa
These videos are amazing, they have really helped me with my university revision. THANK YOU :)
Thank you for presentation. Good luck!
Your little hornworm friend should be named Horace, Horace the Hornworm... Though by now he'd probably be a sphinx moth...
fun fact: the woodlouse (aka pill bug, aka roly-poly) looks like an insect but is in fact a land dwelling crustacean. It actually has gills!
source: en.wikipedia.org/wiki/Woodlouse
Technically insects are thought to be part of the crustaceans (according to molecular analysis) although it is still debated.
Something i will enjoy watching during the summer
These videos are helping me pass my biology course. Thank you.
12:55 Name him Phil
Love your series on animals! - but what about Echinoderms?
I love this show. It's great that my 6yr old loves this show. Thank you CrashCourse.
That was so helpful!!! Who could have explained that better? I got a 100% on my test because of this video!!! Keep making these videos they actually help. And who eats food while watching a video on insects... There is a title for a reason :D
Oh look, it's Heracross!
Pokemon Nerd
Hey there's a Caterpie!
Automotive crash course! Oh, wait, that doesn't sound right.
Hank is so precious when he's describing the larvae and pupa of the rhinoceros beetle lol... also, the " I LOVE MY CATERPILLAR" line is so cute
Thank you, sir. It was an awesome lecture.
Thanks for not doing a close up on the arachnids :)
WHY DID I WATCH THIS BEFORE BED?! I WAS NOT PREPARED FOR THAT PUPA TO MOVE
By far my favourite video:) But they are all great.
I'm here not because I have a test coming up... But because I'm writing a fiction story about arthropods!
I am terrified.
In honour of making my bio lab test so much easier, name the caterpillar....*drumroll* LUCY! (cuz why not)
I wish we had covered this in my IB Bio class. I remember reading my study book for it and looking at all the extra HL topics that were so much more interesting than the ones my teacher chose, and I think this was one of them. Thanks Hank!
hank you are my favorite you tuber, i watch your videos just for fun
I knew some of those words.
Chase Homan haha i think thats a good sign
+Demifurrr dc xxv.

6:55 whatever greeks
this is awesome!
Thank you, I have an A in my zoology class because of your videos! :*
Hank is pretty cute at the end of this video.
To be fair - he's always cute. hashtagSorryNotSorry
Rick Jackson It's true. Him AND The Katherine.
lol @ "they might".
I literally replayed that part so many times
Thank you so much! This is some useful stuff. 😀
I just really enjoy listening to his voice.
You could call it "Shai-Hulud".
I highly regret turning on this video while eating dinner
Love ur work .
more ppl need to watch these!
It always bugged me how words such as "Arthropods" and "Arthropoda" are used. They both come from the plural of "Arthropod" and we tend to use them in different situations.....
That applies with Annelids and Annelida, Chordata and Chordates, Nematoda and Nematodes and basically most phyla.
...It always... 'bugged' you...
Molluscs and Mollusca
Annelida is actually latin for little rings, not greek. @2:34
True, i am greek and that's not greek
I read that as "True, I am greek and that ain't geek" like you where some rapper
Annelida ist both, annus -> latin, eidos -> greek.
When speaking of greek in science, they usually refer to Ancient Greek.
Love you hank!
i love crash cousre hank makes science easy and funny
Warning: Strongly Religious People Beware: Evolution is a huge Subject in This Long Playlist of Biology
Thankfully we haven't had to many of them on this video.
killerbee256 God shall be praised, for there aren't many of them... Wait a minute XD
I skipped all of them
I was totally fine with the intro until I realized those bugs were REAL!!! Almost contracted severe muscle spasms from violent involuntary squirming. Aaaarrrggghh!!! Don't even get me started on those close up shots...!!! Thank goodness for Hank, though. At least I can learn about them through my computer screen, far removed from those... those... Aaaarrrrgghhhh!!!!
yyyaaa! i hate bugs 2!
I thought they were plastic at first then he pulled out the worm and I was like whaaa????
what a fucking girl
they arent arghthropods
this is awesome. im 21 now and im still a nerd for this
hank is just too perfect
I have first cousins that are less complex, interesting, and attractive than your beetles and earthworms there.
DON`T YOU FIND IT GROSS HOLDING ALL OF THOSE BUG IN YOUR HANDS I WOULD HAVE TROULBE BEING 5FT AWAY!!!!!!!
Kate Senatskaya i like snakes! weird ryt? lol!
love your vids!
awesome show
eeeeeeeeeeeeeeeeeeeeeeeeeew Hank just touched a worm OMG! >.
At least use gloves
But y
I had to watch this video in 0.5x speed and I just kept laughing all throughout the video because Hank sounded really bored and tired. But then he makes his little quirky jokes and it is 10 times as funny because you can really see the awkward expressions on his face. haha! I love it :D
A bit off topic, but I just noticed how good the advertisements generally are before the Green brother's videos. Some of them are so informative I occasionally get caught up and find myself forgetting I'm supposed to be watching crash course...
Hanks face when he commited the Mite pun was priceless xP
Thank you so much for saying centipedes and millipedes before you actually showed any! You've saved me weeks of nightmares because I was able to look away in time.
I'm depressed that you guys made these later than May (AP Biology Exams), yet very happy that they exist all the same. :)
I have a feeling that Hank is going to keep all those little guys. By the end of the season he is going to have so many animals in his home.
Question: once both of you have completed your respective series, will you bundle the files together for easy downloading?
i just want to say thank you so much for making these videos! they help me so much! you make biology interesting! my boyfriend thought it was very interesting especially when I tossed my computer halfway across the room when the beetle flashed across the screen! that thing is HUGE! ever since the mummy I am terrified of beetles!! but I managed to pull myself together and enjoyed watching your video.. thanks again!
I wish I had this during my first year of undergrad, it would have made my life so much easier!
Hank! Look! I'm watching crashcourse videos for homework!
My bio teacher is awesome.
you are amazing G.B.U
"I love my caterpillar!" was probably the cutest thing I've ever heard
Woah! That huge beetle is well wicked!
you make zoology 101 not boring mate I thank you
This is one of 3 videos I know get posted on Mondays that haven't shown up in my sub box
love this video!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is probably gonna help me pass my bio final. Thanks. XD
Very interesting
