0:07 Sea Otter (Enhydra lutris). But I had an unfair advantage in having prepared study skin/skulls of several Mustelids during my favorite course of all time, Mammology. Yes, I was That Wierdo whom was always first to jump into dissecting things, but it paid off when the professor gave me free rein to examine anything I wanted in the college's collection. :P
1:00 I'm pretty sure the Fissipedia and Pinnipedia dichotomy is defunct now, because it was more based on characteristics instead of evolutionary relationships. Kinda like the former "waste-basket taxon" that was Insectivora. Currently Carnivora (which is itself now an order, not a suborder, or at least how I was taught) is divided into two suborders, Caniformia and Feliformia, and pinnipeds are in Caniformia, infraorder Arctoidea, along with bears and musteloids, like mustelids, skunks, etc. In other words, pinnipeds are closely related to some terrestrial carnivorans, more closely than many terrestrial carnivorans are to one another. Obviously we can split hairs about ever-changing classifications all we want, but I thought that point was conceptually important enough to point out. But if you have an alternative argument I am certainly open to it. The thing that's surprising to me is that according to molecular phylogeny of six genes in Flynn, 2005, Arctoidea contains a clade called Mustelida, which in turn contains Musteloidea (mustelids as we know them, along with skunks, raccoons, and red pandas) _and_ Pinnipedia. I never would have imagined that pinnipeds were the most closely related to mustelids, a very neat idea. I did not get it right, however. I thought it was a badger lol. But in my defense I'm pretty sure we didn't have sea otter specimens in my mammalogy lab.
@@Baldgo Fissipedia isn't a valid group. In the past It was believed that the fundamental division within Carnivora was between land-dwelling(Fissipedia) and aquatic(Pinnipedia) species. Today we know that the most fundamental division is between a cat-like lineage and a dog-like one. Pinnipedia is a subgroup of the second. In modern evolutionary biology a group, to be valid, must include all the descendants of the most recent common ancestor. Fissipedia excludes some of the descendants so it's not valid.
You got me liking wet specimens now. I've always like bones fossiles crystal etc. But this stuff is so interesting like I could spend the day listening to you go on and on never get bored at all. 😁
after seeing the nostrils I thought it was some kind of felidae since it reminded me to felids skulls, and the incissor count seemed alright. then you showed us the molars and my theory was totally ruled out hehe (now that I'm rewatching the video, the skull shape looks nothing like any felidae but I guess thar short snout tricked me) I love these videos, I hope to see more of them. Skulls are really interesting :)
I got it right by looking at the thumbnail but I really like the walkthrough of how he gets to the conclusion and so much information he gives about other species like the different size of molars and the fact that reptiles have multiple bones in their jaws. So cool.
I recently found this series (with skeletons and skulls) and I can't get enough ! It's so fun to learn and try to make a guess with you ! Please make more and make a playlist of it so I can binge watch them again and again. Please please pleeeeeeeeease !
Me : its Probably a mammal him : Explaining me : ( waiting for choices ) Him : Sea Otter Or Badger Me : Sea Otter ( You can See by the Teeth ) Him : Sea Otter Me : Exactly !!!! Him : lets GOOOO
I got this one wrong but it's funny how I do come up with your last few ideas of what it could be I said badger. Win some, lose some now I know and knowing is half the battle!
I'm slowly learning that I know way too much about animals if I can guess the animal with 10 seconds. I guess watching all those wildlife/nature discovery channel shows has paid off.
I frequent the California Academy of Sciences in San Francisco, and I've seen Sea Otter Skulls many times, I knew before the timer started. lol I love this series
I no shit guessed sea otter when I saw the thumbnail, because the 4 big canine teeth and flat skull instantly reminded me of a giant sea otter from a documentary about the amazon rain forest.
The comemnts always saying "I knew it as soon as the thumbnail" annoy me. The difference is small compared to other mustelids... are there this many mammal experts watching?
Not that I've got much to add. *DO YOU HAVE SPIDER-GOATS???* This is a comment for the algorithm because I like this channel and wanna give it more views... *REQUEST* for more arachnids please. Particularly about tarantula "paws", claws, and spider webs from their FEET as they walk, WHAT?! Anyway, orb weavers have the strongest substance known to mankind coming out of their spinnerets! Even the US military wants that, they made some goats who give spider milk now.
Always subtract 50% off the time for the fact he is also explaining it to people so impressively that even a simpleton can understand. I love that even while trying to rush he can teach people so much about something they may know nothing about AND they'll actually take something away from that. Bet the school system can't say the same thing.
When you narrowed it down to a Fissiped (which is no longer considered a viable taxa) the shape of the molars suggested a creature that crushes hard material so that was my clue to *guess,* not confirm, that it was a sea otter.
They're called nasal turbinates, and they're very delicate bone structures that help air flow over as much surface area of nasal mucosa to clean the air before it gets to your lungs! They're very very delicate and in a lot of mammals are almost kind of spongy feeling. In human skulls they're not very obvious, but in a lot of other mammals they're very obvious, especially carnivores
@@batfurs3001 it was such a wild looking structure so close to the opening of the nose that I was surprised and a little disappointed when it found out we only get like three slightly curly plates as humans
This is an explanation speedrun. In an actual speedrun u could immediately tell the order and even the exact soecies in seconds. Like I'm not even educated in biology but I was like yeah that's a Carnivora species from the first few seconds
0:03 cat of some kind, feline 11:00 ... 50:00 pinniped probably, totally forgot about them as I don't live near the ocean 1:16 badger probably, ive seen mink and it aint mink 1:34 sea otter, idk but it seems aquatic the teeth smoothness or something
Is a sea otter being a member of fissipedia just a misnomer of English language animal nomenclature? Are they primarily a terrestrial species? Trying to connect the dots
Sea otters have a lot of features that are more like terrestrial mammals rather than aquatic. I think they are a relatively new species to the aquatic thing. Although most fissipedia are terrestrial, otters are an exception, being more closely related to weasels than marine mammals such as seals, which Pinnipedia is mostly made up of.
It’s amazing how fast I get these. Big ol’ honker on that one with the teeth I knew it was an otter. 🦦 I had a backpack in jr high and that nose was my comfort blanket.
I really like these videos where you identify based on the skeleton with little to no information. These are awesome; please make more!
I am shocked to find out he swears so much in older videos, but not dissapointed.
Bring back the swearing we love to hear it
Well shit, you got it!
@@OddAnimalSpecimens no please no no no no i am religious dont
@@slametdinatadinata645 lmao we don’t care
No we don’t we hate to hear it
@@slametdinatadinata645 we do not care
man how are you this underrated? your videos are insanely fun to watch.
1:43 seconds I said badger:(
BRO HIM SWEARING THE WHOLE TIME MAKES THIS SO MUCH FUNNIER 🤣🤣🤣
I like how he says "lemme know if you can beat my time" like thats gonna happen
That's pretty easy 😅
I guessed a mustalid atleast, and the huge Naval cavity really gave it away

Once he confirmed mustalid, that giant nasal cavity gave it away.
I got this one wrong but it's funny how I do come up with your last few ideas of what it could be I said badger. Win some, lose some now I know and knowing is half the battle!
I guessed it once you said it's from Mustalidae family and also because your other video gave me a hint.

“It’s definitely not an insect”
No shit Sherlock
I no shit guessed sea otter when I saw the thumbnail, because the 4 big canine teeth and flat skull instantly reminded me of a giant sea otter from a documentary about the amazon rain forest.
Me the entire video: "Yhea. Hmm. Precisly what I thought"
I guessed it was a sea otter when I saw how huge those molars were. Definitely look like something used for crushing shells.
:04 sea otter. I think i have an unhealthy habbit of looking at bones and skulls
Learned from your other videos and having fettets guessed sea otter from the outset!!!
Got it! You said semi aquatic, and I knew right away.
Nope! My guess was a wolverine. Same family, close enough. :)
"Not an insect" I'm pretty sure no insects have skulls 😆 lol
I instantly knew it was a terrestrial carnivora, like u shouldnt waste a minute 💀
Explaining it to the people who wouldn’t know
can't wait to see your sekiro speedrun.
i knew it was an otter the moment i saw it's stubby nose and big canines
The comemnts always saying "I knew it as soon as the thumbnail" annoy me. The difference is small compared to other mustelids... are there this many mammal experts watching?
Why do those molars look like yummy little marshmellows?
Let’s gooo, my expertise in Mustelidae prevails! Otter GANG

"the f*ck is that eye formation-" "bro those teeth look weird" "Why are it's 2 front teeth like baleen?" "Looks like an otter"
37 seconds. I just guessed with how the nose looked lol
It took me 5 seconds to figure out that skull was a "Sus scrofa"
As soon as I saw it I thought of a bear
Dammit I was so close. I thought it was a bager
Nobody’s gonna believe me but literally the moment he showed the skull i was like that’s an otter 😂
I actually thought it was a badger
I am loving these videos!!!
0:45 sea otter
I guessed rat
Sea otters are that big? I guessed a tiger.
I’m taking those bad words personally.

This guy mistaken his mother's coffin for a brown crayon
looking inside the nose makes me so uncomfortable
Would love to know more about what in the world is happening in that nasal cavity.
Smelling

@@pipolwes000our muzzles got the pug treatment, so our fun swirly dealies are hidden from view 😔
I'm guessing sea otter without even starting the video, just based on the shape and teeth
Edit! Yesss! Less gooo!
"or mink" ONE PIECE REFERENCE
I would love to be able to do this, how did you learn to identify all of these things?
This is an explanation speedrun. In an actual speedrun u could immediately tell the order and even the exact soecies in seconds. Like I'm not even educated in biology but I was like yeah that's a Carnivora species from the first few seconds
Impressive
47:18, I could tell by the nasal cavity
It’s a black bear less than two seconds
damn, otters are the group i know the least of probably, couldnt figure it out
YES i was guessing otter
Sea Otter 0:10 or Amazon Otter 0:15
i knew it was a sea otter ever since the start
I got this as soon as I looked at it, I’m so proud of myself 😄😄😄
I'm disappointed it's not a fish.
My time was zero, cuz i knew it from the thumbnail alone
0:03 cat of some kind, feline
11:00 ...
50:00 pinniped probably, totally forgot about them as I don't live near the ocean
1:16 badger probably, ive seen mink and it aint mink
1:34 sea otter, idk but it seems aquatic the teeth smoothness or something
What would the molars look like in a semi aquatic predator?
That was fast
🤔
Sea otter
OTTER
OTTER!
I guessed river otter. Dang.
That is a xenomorph
right😂 (a small one)
Nahh ita a fish 🐟
OOOO I know this... wait for teeth but otter! :D
yeah letss goooooooooo :D
I GUESSED IT I FUCKKING GUESSED IT IMMEDIATELY I haven't felt do proud of anything i have done in a really long time
0:42 maybe a badger 🤔
Edit: aleast I was close
Could u do this again but prehistoric mammals?
Where in bloody hell you buy this
...I want one
lol i called it from the beginning
That is definitely a lion
I thought it was a cat *cough-*
I had it very quickly then panicked around the terrestrial part and second guessed myself 😔✌️
So it was an otter! You confused me with excluding “semi aquatic carnivores”, aren’t otters them?
It’s a sea otter, and that took about 1/2 sec.
This vid makes me wanna break a pencil idk why

Ngl I knew it was a sea otter no cap
It’s amazing how fast I get these. Big ol’ honker on that one with the teeth I knew it was an otter. 🦦 I had a backpack in jr high and that nose was my comfort blanket.
I’m guessing cheetah
Based on the thumbnail, I thought some kind of monkey, because the skull looked so round. Not so round, actually. I guessed sea otter at around 0:30.
Who are you?! I'll find out actually I'm like four videos into binging your whole channel so I'll comment again later and let you know.
How did you learn all this????
I acctually got it right
I think its a fish...
It's funny when you f***ing swear🤣🤣🤣🤣
