All animals originated in the sea and then evolved to come out on land, however, throughout prehistory many different groups of these animals have then found there way back into the water readapting certain features. This would include multiple lineages of birds, reptiles and mammals but strangely enough the one group of animals that seems to have struggled with this evolutionary pathway are the amphibians. However, there was one time where the amphibians did take to the sea and adapt into many forms around the world.

When you're promoting a language program, make sure to check your pronunciation. You said pro"noun"ciation, which is actually incorrect. One would think that the "noun" sound would be retained, but it's not. The sound changes to "nunce" when using the word.
@@c2jones Some people say it that way. It's called an accent
@CHRB-nn6qp
No. This wasn't an accent. It was clear mispronunciation.
"lesser known languages like afrikaans 😭
@@c2jones That's how I and many people I know say it. I don't think it's as clear as you think

I had gone to bed. To sleep.
Funny as time flies when you surf around the interweb.
Not so fast buddy, time to take a little journey to long lost Amphibia.☝️
and now you're gonna have dreams about being pursued by giant predatory amphibians
saaaame
I just woke up😂
I have a few suggestions for future videos
1. The development of bipedalism and why it's so rare
2. Why more animals aren't omnivores
3. When did earth first have freshwater
4. Why pack hunters are rare
5. The evolution of vocal cords
6. The limits of multiple births among placental mammals
Dinosaurs (including birds) are very bipedal, I'm not sure it's that rare?
That's a solid list and I hope all of them gets made.
Too much competition for many generalists. Specialists can exploit each niche to the max.
@@davidhouseman4328 If you compare bipedalism to every species in existence it would be very rare
@@kingcosworth2643 Sure, but looking at every species they wouldn't locomote, those that did would swim or travel on 6 legs. Maybe it's a different use of rare but when you have massive groups of bipedal animals I don't see them as rare.
I would ask the same question for arthropods specifically terrestrial insects. To my knowledge only one group has returned to the sea.
I think it's because the tracheas of insects are less efficient at breathing underwater than the gills of other crustaceans like crabs (insects ARE just a group of highly terrestrial crustaceans) and that the latter already occupied most of the marine arthropod niches available.
the only route i see is some sort of neoteny given that many insect nymphs or larvae are freshwater dwellers and have a form of gills whereas the adults have spiracles. although then they could run into the same problem as amphibians given theyre freshwater adapted. the reason i think the adult form transitioning to water is unlikely is because their small body and tracheal system probably arent really well adapted to a "dive and take breaths from the air" life.
@@Red-MagicOrchestraMany larval forms of aquatic insects are born with gills.
not to sea, but there are plenty of clades that have become fully aquatic, which is arguably still very impressive given how they breathe
Also enchinoderms and cephalopods failing to venture further than intertidal. The Epelutte Shark is also attempting this. It’s odd that benthic animals aren’t necessarily good at adapting to land.
Babe wake up, Moth Light Media just dropped
Yeah, they're like a modern grown-up version of an "after-school special!" We await them with great anticipation!
I love it when you coincidentally pick up a topic I've been thinking about!
I had 5 similar moments where I watched videos which content came in school shortly after xD
Serina is cringe.
Amphibianbros, it's time to rise up
THE AGE OF FRESHNESS IS OVER!

Always a pleasure to see a new Moth episode.
It makes me think that the transition from water to land was primarily done from freshwater, since the first groups of land animals seem to have it easier to readapt to freshwater rather than saltwater.
It also makes sense, since brackish or saltwater is less stable, and would force organisms to adapt to more variable temperatures and ion concentrations, all preconditions for terrestrial lifestyles.
@novedad4468 Not to mention that rivers are more prone to drying out, thus putting immense pressure towards the more land capable individuals, and freshwater also can put pressure towards being able to breathe air due to how much of it can be muddy and oxygen deprived, see how many types of freshwater fish today are lungfish for example. Freshwater is just the perfect jumping point towards the land and living in freshwater environment by default will give organisms an incentive to evolve towards being more adapted to the land
Freshwater is just easier to deal with regardless.
Also
Amphibians need to breathe air.
There is very little shallow salt water for amphibians to live in and give them access to air.
@@keithfaulkner6319 well yes, but all secondarily marine tetrapods need to breath air, so that by itself wouldn't explain the difference
I’ve been wondering about whether amphibians ever did this! Thank you!
There are many channels like this that try to make short, info videos on a certain topic but none of those channels consistently deliver one banger after another like your channel. I love your voice, your narating style and your content. In my opinion you belong to the Top 10 youtube channels
1:53 ah yes, Lissamphibian Al Gaib
I found my favorite comment
Uploaded 16min ago and i already watched it, your content is addicting. Thank you^^
Woo got lucky enough to happen to check the homepage just as you uploaded :D
I love seeing sponsors on your videos. Not because I'm seeing an ad, but it's proving that sponsors are interested in funding you. Great job
Phytosaurus : i was the first to look like crocs
Trematosaurus : no it was me
Prionosuchus : NUH HUH IT WAS ME
Prehistoric amphibians are so underrated
What's interesting is how many converged upon similar body plans that later species would adopt
Fascinating info on amphibians. Thanks for your work!
We need more videos about big Amphibians :) (Carboniferous period videos)
I stop what ever I’m doing to listen to this
I love the serious and calm nature of these videos. Massively entertaining and wonderfully intriguing all at the same time, all with beautiful artwork to make the imagination go wild with all we might never know that has happened before us. Great work Moth Light!
Such a joy! I really look forward to your episodes. Always pleasant and informative. A wonderful mix.
There's a lot of good biology/paleontology/evolution channels on YT, but yours is perhaps my favorite. It's as informative as it is laid-back and calming.
9:48 how salty were the oceans back then? That could have been a factor depending on salt levels back then
Lees than today
Amphibians get hard carried by their larval form.
They:
• Are extremely efficient filter feeders
• Can feed of algae and detritus in the water, including semi-terrestrial tadpoles like phytotelmon-dwelling ones, which most tetrapods cannot feed on
• Can move and thus defend 🛡 themselves by running away soon after birth
• Give a lot of resources and time for their adult form to develop, ensuring it is of high quality i.e. not a rush job
The direct development frogs/salamanders amphibians are just kinda there. They just exploit empty niches, without really having much staying power if local geography changes.
=========================
Tadpoles are pretty bad at adapting to the ocean, because there is not as much algae (as there are more algae eaters), many more parasites/predators, and no safety to exploit the long time for adult development for higher quality bio-construction 🏗.
Have a Merry Christmas and a happy new year mate!
AMPHIBIANS IN THE OCEAN?!?! Can’t wait to see how that happened 😲
AMPHIBIANS IN THE OCEAN?!?! Can't wait to see how that happened 😲
So the question on my mind is “when did amphibians or their fish ancestors lose their salt tolerant capabilities?”. Did fish lose those adaptions before they developed limbs or even before they started gulping air? Maybe there is a direct correlation between early Amphibians losing salt tolerance and gaining more terrestrial adaptions. This is just speculations but I feel like there is something there and it makes me curious.
The Sarcopterygian fish that gave rise to Tetrapods may have been freshwater species much like the Lungfish so the loss of salt tolerance probably started before the limbs evolved
Just in time for my lunch
XD same!
I already ate supper.
I ate supper.
I'm exploring this in my spec evo seed planet scenario. So far, I'm primarily focused on the descendants of both crab eating frogs and natterjack toads, but I wanna expand into other amphibians that might take to the sea for one reason or another.
Very clearly explained. Thank you.
thanks very much for this! i've been weighing options for a while on if amphibians even COULD evolve into a marine niche for one or more speculative evolution projects of mine, and this'll be a great starting point :)
Thank you, Moth Light Media for bringing back the old opening for this episode, I hope for good.
This channel strikes the perfect balance for me. No goofy jokes and clickbait titles like ExtinctZoo, no airhead presenters like PBS Eons. Just a calm soothing voice and more research-focused. Also, the image and clip selection is perfect as well as the diagrams.
I enjoy PBS Eons. I dig the vibe and all that but Mothlight hits in a different sort of way. I appreciate the no-nonsense approach to giving the facts while still giving an approachable vibe. Both Channels are good but each fills a different niche in science education content. Eons speaks to a wider audience while keeping its integrity whereas Mothlight isn’t afraid to get into the nitty gritty by elaborating on more complex concepts while maintaining brevity and even a certain amount of approachability. This is my opinion and I understand other peope may differ in theirs.
@@justinmarino5601
The issue with PBS Eons is that they tend to parrot various unsubstantiated or outright discredited claims about clade-level outcompetition.
There was that time when they argued Livyatan was one of the factors in megalodon going extinct when a simply Google search would have shown it went extinct BEFORE megalodon…
@@justinmarino5601 Indeed, there is also that aspect of the short average duration of Moth's videos (not too short) which makes for perfect science communication because it keeps things digestible and interesting.
PBS Eons references a lot of research but the content is very light-hearted and "all-ages" so you get the feeling of being spoon-fed. I prefer a serious tone. I think they make their illustrations in-house but with the amount of funding they get (including from government) they better have high production values.
my boys got sponsorships!!!
Great video as usual thank you!
I have always wondered this!
I was always curious if amphibians ever interacted the oceans, since some amphibians were strangely found in informations that also included marine Animals as well.
Holy… the videos are dropping like flies (titanopteryx my beloved) Amazing work as always🙏
I get pumped for these videos in a way that I cannot express properly to non nerds
Yay, the classic intro is back
Wonderful video about an argument that ever intrigued me
Always a pleasure, thanks for the video 👍
I love this channel
I'm supposed to get ready for work! Oh well... I'm sure my boss will understand why I'm late.
Thank you for your insight into why amphibians have not frequently succeeded in marine environments. (And also for your perspective that they are, indeed, "brilliantly" adapted to freshwater environments!)
I loved this video.
Hey, frien, you should do a video about the evolution of tiny animals, like mites, it would be very lekker, thanks!
Thank you.
Should make a video on why animals evolved to become multicellular, and how it works. Bc there’s literally no videos that explain it good like this guy would
What actual evidence is there that large Triassic amphibians had smooth permeable skins?
It's probably inferred given our current understanding of amphibians there's only a limited amount of information that can be gleaned from fossils
I'd imagine they probably did not.
As breathing that way is much less efficient as bodies get larger.
Plus, it makes dealing with saltwater and arid environments much easier.
In my 2-3 years of watching this guy on various different accounts I have never seen him reply to or heart a comment
yeah he doesn't engage with his audience at all, but he doesn't have to. I think he does read the comments though, because he reversed his decision on removing the intro and changing the background music, due to people overwhelmingly asking to bring both back.
@ I see
I really hope when we die we get to see the origins of life on earth in order from the beginning til now. Truly shattering what we thought we knew on this earth. There’s no way even the smartest of humans know exactly how earth was millions of years ago.
What's the name of the music in the background?
so nice
I think there's still oceanic amphibians. I seen one when I was a kid it was about a foot long very flat with a triangle shaped head. It swam away as soon as I got near it
Weird to think an amphibian could adapt to salt water. I still try to wrap my head around the size of Prionosuchus, though I know it didn’t live in the ocean, just that that got so big! I wonder if amphibians will still be around in the far future, haven’t there been lots of die offs in the last few decades?
time to remake Jaws
Take back the virusses you used to surveil my search history. You only made this video because I googled why there are no marine anamniotes some days ago. ;D
I love your channel because it isn't sensationist, I would have said seas rather that oceans as because it doesn't seem like these are open water creatures.
6:15 why saurus, when it is an amphibian and not a reptile?
It's usually because whoever discovered it incorrectly assumed it was a reptile, see: basilosaurus.
@@rachelblake2350 we really need to rename Basilosaurus.
@@zoltanperei4789 unfortunately, once scientific names are given, they stick in most cases
New Spec-World players discovered!
are there any theories as to how those amphibians managed to adapt to saltwater?
This makes me wonder how these ancient amphibians were able to be adapted to marine conditions. They cannot have evolved from freshwater amphibians because the same permeability of skin problem would have applied, or at least not from freshwater amphibians like we have today. So either there is a continuous line that were always marine, or their skin was fundamentally different - did they have scales like fish do? Impermeable shin? Or was the skin permeable but with major internal adaptations for marine life?
Cephalopods are like the inverse example, a group that can never adapt to freshwater due to their unique biology (including extreme permeability of the skin).
"This means they are by nature just statistically more likely to be closer to an ocean." --Um, no! I don't see what needing to be close to (mainly freshwater) aquatic environments has to do with proximity to the ocean.
Yes, its Koolasuchus time
Ambulocetus looks like a stretched out Opossum.
9:53 yea but WHAT IF:
Anfibias suffered an early split between saltwater and freshwater and the saltwater ones became the reptiles and so???
Me in the modern day knowing I’ll never get to pet a huge prehistoric marine amphibian:😞
So in all probability true amphibians didn't come about until vertebrates had a firmer foothold on dry land
This may be why amphibians don't have a significant presence in saltwater habitats
Their permeable skin may make respiration more efficient but also extremely vulnerable to distinct changes in their ecosystems however gradual they may be
It may seem intuitive to think that amphibians' ability to breathe through their skin would give them an advantage in coastal marine environments but few species have adapted to be able to tolerate the level of salt found even in brackish waters
I think it may because amphibians originally evolved in freshwater habitats but some had adapted to saltwater habitats in an earlier chapter of Earth's history and have yet to do so in the present day
Wake up babe, new mlm video
Wait what? They did? I thought they were strictly freshwater?
Oh it was non-lissamphibians.
I wonder if the background radiation played a big part in driving evolution?
Anybody ever think about this?
LISSAN AN PHIBIA!
Adaptive radiation makes for some odd taxa haha
Sponsor in the middle of the video :c
Dimitry Bogdanov carrying the whole paleo art genre al by himself... what a chad!
Can you put the sponsor at the end of the vid, so it's easier to skip?
Wait, does that mean Ichtyostega, Hynerpeton and Gaiasia were strictly freshwater or are they not amphibians?
What about very early land animals ? Did some of them return into the sea? As their ancestors came from it not that far before, their skin probably was still more fishy ;)
What are the birds that successfully made it back to the water? I'm assuming it's not penguins, that are not full time aquatic animals.
so far
Didnt most of the fleshy lobed fishes originally came from salty or marine environments??
Could modern amphibians evolve to adapt marine environments?
Time will tell
And why aren't there freshwater cephalopods? Or tool-using cephalopods? They've had plenty of time.
I know it man
excuse me, mothlight media what happened to the original narrator
Started the video on mute because of an ad I had to ignore
Turned the volume up late so started the video over
Turned volume down because another pair of 30 second ads
Realized I hadn’t turned the volume up
Started video over
Disliked video because of so many ads.
I would like to make a video with you. Is it possible to make a video together,
I slightly disapprove of those periods after mass extinctions when heaps of nonsense species evolve. I get that everyone is just trying their best, but it feels like a lot of species are clearly on the wrong track and will eventually go extinct, but then they get entrenched and cling on for way too long.
And then they somehow manage to survive the next extinction event and evolve to be even worse.
Because you see, the real evolution is not about the survival of the fittest, it's about surviving the inevitability of the next extinction event.
*So far
5:10 ad skip
Until marine crocodile exist
please don't use auto dubbing. At least German is awful
