This video shows the transtiion that seals took from land animals to ocean going specalists and how their appearance spured on the evolution of other groups and were adamant in the seas taking on their current form

In its own weird way the walrus is technically the "sabre-tooth tiger" of the seal family
Narwhal is the unicorn of the marine mammals
@@fernandocouto4774 Yes I know the narwhal "horn" is actually a tooth. Still stand by my comparison tho lol
Here b4 someone says the obvious that saber toothed tigers weren't tigers
@@camacakegd3714 No, they weren't 😂 I think they were more related to Lions or Mountain Lions
Saber tooth seal
I hope the proto-seals made the same funny noises.
The Flaine Like "AAAAAAAAAAAAAAAAAAAAAAAAAAAAA...
egg"?
But smaller~
They probably liked other things aside of eggs
Oh, just search up "seal wants eggs and love" because i was referencing to that video.
@@viiiderekae if i remember correctly they also like l'egg and hnnnnnfffffppff
Proto-seal: sleek and fast boi
Modern sale: *cute chonky boi*
Modern sea lion?
Modern seals are also sleek and fast when swimming
I just want to take a moment to thank all those archaeologists that spend so much hard work to bring us all this data that makes our history. Without that information, we could never know the connections that brings us here today. Thank you.
these are palaeontologists, they study fossil organisms. Archaeologists deal only with man made things like buildings, tools etc.
@@caviramus0993 thx 👍❤
I’d love to see a video about walruses because of how different they are
I think I might because they had some really interesting prehistoric relatives as well
Yes please. The walrus needs more attention.
I love you guys.
Nobody cares about my walrus comments in PBS eons vids.

@ true alpha
i had no idea seals were so (relatively) closely related to bears! so cool
Nonsense. If a bear freakishly gave birth to a seal it would immediately eat it
Makes it weird when polar bears eat seals.
RNAUGH100 that’s not how evolution works lol
Yeah the bear , seal , and dog family along with the cat , meerkat and hyenea family all share a common ancestor of a small weasel like animal that lived in the trees when the dinosaurs lived on earth but after the dinosaurs died it started to evolve over time like the other mammals and it started to take many splits and then it split into two groups. One half went onto the bear , seal and dog family and the other went onto the cat , hyena and meerkat family .
Wait so that means.....its a sea bear!
The fact that seals aren’t called “water bears” and the fact that “water bears” is a word for a microbe is possibly the worst marketing blunder of all time.
@Gaptooth Goblin either we called seals "sea doggos" or "sea bears"
And polar bears eat seals
The German word for seal is "Seehund" (sea dog). And we call fur seals "Seebär" (sea bear). So yeah. :D
And then you consider how killer whales, as cetaceans, are related to herbivorous hoofed mammals yet they eat sea bears and it just gets more weird and confusing.
@@robwalsh9843 land: carnivorans eat artiodactyls.
Sea: artiodactyls eat carnivorans.
On land caniformia (dogs and their kin) prey on artiodactyla (even hooved ungulates, such as cattle, goats, gazelles, deer,...).
In the sea artiodactyla (whales, such as orcas) prey on caniformia (seals).
It looks like the tables have turned.
Pedro Figueira how the turn tables.
For now...
That's the way the crumble cooks.
That’s how the... wait I just lost my thought of train
As a Seal. I can say this is accurate.
Thank you very much for caring about our species. Your content is incredible. Subscribed!
So you're a selkie?! Nice! I've always wanted to meet a selkie! :)
@@rachell452 Well, I don't turn to human on land. I'm just a seal, but... hey! nice to meet you :)
Thank you, I'm glad it gets your seal of approval
@@TheSenileSeal ah I've never spoken to a seal before, but it's a pleasure! But I'm curious, how do you type with flippers?
Regina Phalange, very carefully. These messages take a long time.
I’ve been wondering for the past few weeks if the walrus was a seal or sea lion. Glad to finally know they’re neither.
They're more of sea lions in a way.
There used to be tusk-less walruses too, and one-tusk ones as well.
seals are such a weird species, they're basically a living sausage
Killer whales et al agree.
@@101jir Orca Dolphins
Toss up between marine dog/sausage
Rob Walsh, the Dutch word for seal literally translates to 'sea dog'
So rude buddy.
1:46 Everybody gangsta till the giraffe start swimming.
@The Lavian no u
It would be great if you made a video about the Lake Baikal seal (nerpa), the only entirely freshwater seal in the world which is endemic to Lake Baikal, the deepest lake in the world and the largest lake by volume. Even just a video about the evolution of the animals of Baikal would be amazing because it is home to so many unique species including massive freshwater sponges and gigantic amphipods
He now has! 😊
But what's the evolutionary advantage of being so cute?
Making humans feel sad when they're eaten by orcas.
@Svoon V say that to dogs and cats.
Free food from humans.
Cuteness invokes affection and warmth from others, making it an advantage in children and females.
@@sohopedeco Every marine being is eaten by orcas
You the man, keep it up.
thank you
Everyone knows that Seel evolves into Dewgong.
No dugongs are closer to elephants
Looks like someone missed the joke
@@yourpersonalflotationdevice enlighten me then
RGN001 if you know what Pokémon is, then there’s one named “seel” and it basically changes or “evolves” as they put it into an entirely different Pokémon. The one seel evolves into is dewgong
what about spheal? i forgot what spheals evo line is
EDIT: Sealeo and Walrein, lol i forgot that google exists
Omg the seal's teeth look like shark's teeth. Another awesome example of convergent evolution. This channel is amazing. I'm learning so much.
Me at 10pm: One more video
Me at 2 am: Seals
Damn, that’s literally me right now. Odd...
You and eons are definitely the best TH-cam channel ever
This was a really cool episode!
The leopard seal really fascinates me.
Great video once again Moth light Media, thank you for this brilliant content.
Thank you
Astrum, SEA, and this...are my new favorite channels. I love narrators who are true narrators, unlike others who just love to show their looks on screen while making "cool" jokes.
superb, just ... all this work is top notch, it's breathtakingly perfect. Thank you so much for making these
That's a really well-made video, I expected it to be by a major network but it's an independent content creator, madness! Guess I'll subscribe and see where it goes =D
I love these videos they have evolutions of my favorite animals Pinnepeds
This channel is gold!! I am so glad i found this! Shoutout to henry the paleo guy and North 02 for the collab that helped me find this channel
It feels like the leopard seal said screw it let’s eat something other than fish
good stuff my man. looking forward to each new release :)
Your videos are really interesting and informative.
I'm binging through this channel so fast.
I refuse to believe that seals aren't a first attempt mistake that somehow survived without evolving through sheer BLEEGGH
This is one of my favorite episodes, I've rewatched it so many time lol.
Your videos are so entertaining and informative, you’re one of my favorite creators on TH-cam! My only gripe is that your audio is about half the volume as the rest of the app… I can only really watch your stuff if it happens to be super quiet around me. Is there any way to increase the levels for future projects? 🤗
Just found your content! Very thorough and interesting ! Love this !
To think seals are merely an intermediate state of the potential next baleen-like animals is just so intriguing.
Just like lizards turned into mosasaurs and deers into cetaceans. Bonus round: coastal-wolves are kinda turning into seals as well.
I like this narrator's voice .
This channel is reaching at least 100k subs by the end of this year
Honestly I just love the channel. It’s so interesting to find these facts
It makes a lot of sense that seals are related to dogs lol.
you deserved to have more subscriber
Your channel is so good I wish I could subscribe twice
Another amazing episode
Thank you
Wow how has it taking me this long to find such an informative cool video :) keep it up bruv
Fur seals have been observed preying on penguins.
I’ve seen that too. It was shown on one episode of Planet Earth.
and fricking them
I love how casually he say 30 million years ago like was last summer instead of 11 billion sunrises and sunsets....
yeah, when you spend so much time thinking about dinosaurs and other incredibly old animals you kinda lose the sense of scale that something like "66 million years" represents
Fascinating! Thank you.❤
Seals look like they are not finished yet
Ok, Seals are cute and look like dogs and cute.
I wish seals are more related to dogs than bears.
they still related tho
Both dogs and bears are closely related to seals.
Me too!
Thanks for your research. Very informative. Keep up the good work.
Very informative! Great video :-)
Seals are so cute! I want one as a pet.

“The closet living relatives to seals are bears”
And then you realize polar bears EAT seals.
we also have orcas eating moose, hoofed mammals like sheep and horses are the closest living relatives of whales
Seal=water doggo.
I love this amazing video
Wow I always knew seals were very dog-like but them being most closely related to bears surprises me in the best way possible
Actually seals are actually closely related to both, they are cynofacians, a group of caniforms that consists of larger-sized caniform carnivorans such as dogs, bears, and seals.
Love your channel
Thank you
I wonder what the creationist/intelligent design throngs think about when viewing Moth Light Media videos. I'm sure some of them have red faces with steam flowing out of their ears within ten seconds of the videos.
How is creationism even an issue?.. It's not like their silly claim of mumbo-jumbo by magician in the sky is backed with evidence!
I love this channel
Today's Otter will be tomorrow's seal. Tomorrow's seal will be future's whale.
I don't think you listened.
i've had that thought hundreds of times.
@@needfoolthings it's what happened with marine reptiles.
First ichthyosaurs reached whale like sizes. Then plesiosaurs reached whale like sizes. After that mozasaur reached similar sizes as well. History repeats itself
They're on their way on becoming future mammalian counterpart of plesiosaurs much like how whales and sirenians are to ichtyosaurs
Yes. And todays capybaras and hippos also become more seal like, i believe. And human will go extinct.
I love how they once lived on land but then decided to return to the sea.
Speculation of course:
It would seem every fully marine air-breathing tetrapod got it's start in returning to the sea around the shores of the (paleo)Tethys. Seemingly all other such aquatic creatures never got the hang of live birth at sea and so are tied to land to breed, and to escape really bad weather. One wonders if there was something special about the (paleo)Tethys and now it is no more there will be no more tetrapods making the leap (diving in?) to a fully marine lifestyle?
If there is any truth to this observation - looking at past climate, ocean current models, and likely productivity, my best guesses:
-The transition to live birth in the water may well be about as close to impossible as you can get and still be achievable. Maybe the (paleo)Tethys was the only environment sufficiently benign to make being 'inexpert' at live birth in the water viable.
-Most oceans are notorious for blowing up huge storms from time to time. Maybe not so much the (paleo)Tethys, or at least the geography afforded a lot of shelter. Could it be the weather means you either have to retain the option to escape to land or be very good at being a fully marine? If you 'attempt' to transition from one to the other you'd better hope your environment is very benign or sooner-or-later your or your offspring will drown.
Hope you get 100,000 suscribers soon
Thanks
Honestly these are great even to rewatch
The sea is a terrifying place.
Kinda crazy how from that came Elephant seals
How about baikal seal? There are also other freshwater seals although they are just salt water seals that got isolated in lakes.
amazing video!
these cute seals are endangered :(
Because most humans are pests. Breed like rabbits, pollute the ocean and eating it empty.
It's 12 at night and I'm in the comment section of an ancient seal evolution video, and that's ok.
After the millions of years of evolution seals never 🛑 looking 😍 . (Will most seals 😅)
I love to learn my history
So ...they are literally water dogs. _Nice._
if you like seals maybe watch and support Ocean Conservation Namibia channel they catch seals on the beach in Namibia thatve got themselves tangled in discarded fishing gear and plastic rubbish and they free them from w/e theyre caught in and let them go. sometimes fishing line is cutting into the seals and sometimes there is so much net or plastic stuff it stops a seal catching fish so it it important work bcus the seals would die if no one helped them
Taxonomy is fascinating
Thank you evolution for this delicious animal.
Epic vid
Thank you
I really enjoy the video explaining the fascinating evolution of seals, though it feels weird when your fursona is a literal puijila darwini named l'egg
edit: i already commented on this video like 5 months ago on my meme account, dear lord i'm so stupid
Very interesting thnaks
Please please do a video on arthropod head problem!
If you tell a walrus "Hey you've got something on your shirt" you can get arrested for murder
nonsense
Hi great video! Are you able to provide your research resources?
Look at the description
The fact that seals are related to bears 🐻 makes me believe that mermaids do exist
ALL organisms are related.
@@Dr.IanPlectThey mean that seals and bears are in the same suborder, Caniformia, and are closely related in the same way that humans are 98% related to great apes such as the bonobo and the chimpanzee.
@@thenablade858 I know, I made a distinct point.
bro just use your other account @@Dr.Ian-Plect
prehistoric seals: haha swimmie :)
early orcas and great whites: well well well, what do we have here?
prehistoric seals: oh no
The origin of the Pinnipeds
So a very, VERY oversimplified way of seeing marine mammals would go like this:
Whales & Dolphins: Sea Cows
Seals & Walruses: Sea Bears
Otters: Sea Weasels
Manatees: Sea Elephants
Boat Guys: Sea Men
The old mariners would call seals "Sea Dogs"..bears and dogs have a lineage too. All of these animals share some similarity.
Thanks for this.
I've wondered about evolution of the freshwater seals of Lake Baikal, and if there are any other freshwater seals. An episode?
It's crazy to see how seal ancestors were similar to modern otters.
I would argue that hind limb propulsion is better in calmer water and distance while forelimb propulsion is better for agility and turbulent water aswell as land going.
Picture divers still using their hands for sharp turns and slow speed aswell as coming ashore.
Just an idea on why prefer one over another.
Imagine fishing around that time imagine what you would catch
FUCKING FINALLY! Dude, I've been waiting for this to answered ever since Hank Greene suggested it on Eons. THEY STILL HAVEN'T COVERED THIS! So happy I decided to subscribe!
Loved this video as I was very curious about seals , sea lions and walruses , especially how they all swim differently. Curious
how powerful walrus swimming is because they use all 4 limbs, is this possibly because they don’t swim as much and like hippos more so walk in the water ? Elephant seals are larger and what to they eat that can let them get to those massive sizes ? Also I’m curious how walruses don’t literally destroy clam populations and cause there extinction of their prey and thus later themselves?
Hmm... Very Interesting
I think this is where I came from I’m a really good swimmer and can hold my breath LONG TIME
You forgot the most important thing, the decrease in nautilus diversity
The Seal of Approval
3:15 I though this was a Sudanese basketball players name.
I think that "Puijila Darwini" would probably be pronounced with a hard "J" like in "John" because in Inuktitut "Puiji" refers to an animal that puts its head above water. My Inuk Inuktitut teacher from Arctic Bay taught us the pronunciation with a hard J like in John.
So seals are related to bears?
*_but polar bears eat seals...!_*
