Every Time Things Have Evolved Into Turtles
Throughout the history of life, convergent evolution has resulted in all sorts of creatures evolving to look very similar to one another. One of the most interesting examples is the case of the repeatedly evolving turtles - the Placodonts, the Saurosphargids, the Glyptodonts, and even the Ankylosaurs.

I've always been fascinated by turtles and sharks that supposedly live to be hundreds of years old. Imagine the animal just doing its thing, meanwhile all these massive historical events for humans are happening. Like the turtle was around during the American Revolution, still kicking it today.
No matter how much humans fight over resources, the turtles still just be turtling around.
Unfortunately, they won't. Because most of our resources get turned into trash and end up in the ocean, fucking up those turtles.@@Deathington.
@@Deathington.Until we further damage the ecosystem and kill them all off :(
Just shows you how young the United States is.
That could make for an interesting video; a video about animal species that live long lives.
Turtles, crabs, snakes, dolphins- archetypal shapes for specific lifestyles. I think we'll find similar creatures filling similar roles on other worlds.
Or aliens that look like those creatures. Fluid dymanics is true everywhere.
Without a doubt on planets like ours, imagine on other types of planets there's just some mind blowing stuff tho.
Turtles, Crabs, Snakes, Dolphins. Long ago the 4 body layouts lived in harmony, but everything changed when the snakes attacked.
only if we bring the creatures there to fill them.
Convergence in tetrapods especially really shouldnt be surprising, because the tetrapod toolkit is fairly limited. Four limbs... they can lose limbs, but dont gain new ones, the basic arrangement of organs is fairly set, and bilateral symmetry is standardized. The likelihood of a alien species convergently approaching the basic tetrapod toolkit and then also convergently evolving these Earth forms seems incredibly unlikely to me. Even after a billion years, non-tetrapods havnt convergently evolved the tetrapod toolkit even with the same exact environmental pressures. 🤷
The fact I watched this and said "oh wow so like armadillos" immediately before he mentioned armadillos and then said "ooo like ankylosaurus" immediately before he mentioned ankylosaurs made me unreasonably proud of myself for 1:15 in the morning
Eventually the turtle will evolve into crabs
Underrated comment
Crabs most OP
Crab is the final form
I’ve been reading a book on Ancient Reptiles and it’s fascinating how diverse the entirety of Sauropterygia was and in particular it feels like Placodonts and Saurosphargids were made to mess with how we put together turtle evolution 😂
Title?
What book is it?
@@DawnFire05 Smithsonian Books Ancient Sea Reptiles, by Darren Naish. I got it for the beautiful illustrations but it’s so knowledgeable. I’ve wanted to start reading more and I realized “wait I already read paleontology papers I should just get books on it”
Also published in 2022 so very timely except some new discoveries that don’t really change much save the fact that saurosphargids are apart of sayropterygia as stated in this video
@@Funkiotologistwhat was wrong with Curtis wanting to know the title of the book?
So basically all life wants to evolve into two forms: turtles and crabs. Not coincidentally, both are slow-moving and heavily-armored creatures that mostly (but not exclusively) live in or near water. It just occurred to me that this process of things evolving into turtles could be happening right now. Look at marine iguanas compared to their land-lubbing cousins: a wider, flatter body is pretty evident even though the species is less than 5 million years old. Who knows what they'll look like in 50 million years, if they still exist.
Animals losing their limbs and turning to snakes have been more common. The worm body plan is much more prolific than either crabs or turtles.
The shark body plan is super popular, too.
@@RTaco ?? Only among sharks.
@@JohnDrummondPhoto Ichthyosaurs and cetaceans, too.
@@RTaco good point.
Okay you Turtle, but do you Crab?
Wow I would've never guessed the bottom of the shell was the first to form. Turtles are so fascinating 🐢
dawkins has a nice long passage on turtle evolution in "the greatest show on earth" his book on evidence for evolution, describing this very peculiarity.
I enjoyed learning about how I was supposed to believe tortoises are turtles, because I'm American. Unfortunately I missed that lesson.
A strong foundation is required for any solid structure, whether it is something man made or something that is a product of nature. How could the top of the shell develop first if there was nothing below to support it?
actually for me bottom shell being first has more logic in it but I think I will never get how the entire skeleton grown out . after long years of study paleontology and sedimentology I didn't even come close to understanding this type of evolution. I still think its totally impossible without a written genetic program.
@@AxundSaid you’re not an evolutionary biologist. Your qualifications in other fields don’t make you any more adept at understanding evolution, the same way my qualifications with databases doesn’t make me an expert in spreadsheets, merely an amateur with an interest in them. Don’t Dunning-Kruger yourself into being incurious or writing off a natural phenomenon as false.
I would love more convergent evolution videos. It's one of my favorite phenomenons in paleontology!
same!!
Me too.
Agreed!!
Same! Its my favorite topic!
x6 :)
Turtles, crabs, and beetles are apparently gawd''s favorite children.
Probably mostly just that they are all significantly armored; armored creatures are naturally gonna be resistant to predation. Armor functions without any effort, unlike evasive and offensive methods of defense that require keen perception and skill to be effective.
God apparantly has a thing for small little armored dudes considering how many trilobites there were as well. Humans seem like more of an afterthought.
No... So called black people are

I really like the short explanation of convergent evolution I first heard from Casual Geographic - "convergent evolution is like two people getting the same answer on the same test". It very well illustrates that under similar evolutionary pressures it makes sense for unrelated organisms to develop similar adaptations.
And the two people can be thousands of miles apart.
@maryeckel9682 and millions of years apart
Convergent evolution according to this meaning is simple learning. Two people getting the same answer learned the same thing to be tested on. Therefore they are supposed to get the same answer. Thousands of miles apart. Centuries from each other. Geez. Can you make it more difficult please.
It assumes however that they got the same answers purely by luck
@@philipbaity7083 they got many answers by random chance, but only the correct ones survived.
I feel personally attacked that you assume I don’t know the difference between a turtle and a tortoise.
The arrogance lol
Turtle: tortoise that lives mostly in water Tortoise: turtle that lives ONLY on land
Crabs have a mortal enemy now
Who else heard “Helveticasaurus” and immediately wondered what Times New Saurus looked like?
Since would be Latin probably would tempusneosaurus
I can't believe I understood this joke. Oh my God. Comicsansaurus. Fuck I'm going to go get my degree now just to do this
@@megalofirst1 PLEASE 😂😂 Papyrusaurus Rex has also been on my mind since i wrote this
My instincts tell me that this "turtle" body form is a consequence of surviving in shallow seas, and when I say shallow, think less than a few feet deep. This broadened body plan could have you navigate these areas without breaking the surface, be able to pin yourself to the bottom as a defensive tactic and as a consequence the broadening of the body plan would probably also have the bones naturally widen to continue the flattened body plan and eventually fusing.
Plus if something does see you and/or step on you the shell provides protection.
@@DKShoneys-dc2dp Oh i have no doubt....just like fish that are vertically flattened....creating one dimension of your anatomy to be as large as possible makes it harder for you to be swallowed and thin makes you harder to notice
The plastron emerging first makes a lot of sense to me- as typically many animals focus their defense on/over their underbelly, since the vital organs are arranged closer to the abdomen than the back. Such as Primordial pouch in cats. The Carapace forming afterwards seems very logical
Especially if they were living in the water but breathing air, meaning they would often swim near the top and possibly be attacked from below (I am picturing the way sharks come up to attack their prey) so having a harder belly would be more important than a harder back....if they were being dive bombed by birds perhaps it would be different.
Humans have this too in the form of fat deposits around our stomach, though only some humans primarily store fat there. The downside of this is that it also puts you at a higher risk of developing Diabetes Type 2, so in the modern world this kinda sucks actually.
It would be fun to see a video of this kind on worms, snakes, eels, weasels, and all the elongated critters built for digging and/or swimming.
Let's be honest, we all strive to be the ultimate lifeform; the turt
Imagine if you're swimming in a river and your leg is being hit over and over by a little tiny aquatic Ankylosaurus😂
Evolution and I: I like turtles.
If it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck... unless, of course, it's a turtle or a crab. Everything crabs.

First I couldn’t trust crabs, and now I can’t trust turtles? What’s next?
I never really had turtles cross my mind so i didn't know how cool Turtle evolution was ty!
If I had to choose an ancient marine reptile to be brought back magically It would've been Archelon, watching Leatherbacks blows my mind on how much bigger an Archelon was. Great video as always.
I would go for ichthyosaurus
@@kR-qj7rw Nice choice 🤘, I have a favorite Icthyosaur called Thalattoarchon.

Convergent evolution is always so fascinating... and when discssed on a channel this entertaining and informative it makes for a great experience. Thanks for all the wonderful content
One of my favorite convergence in evolution is lungs. I know it's not a true lung, but the fact betta fish and other fish species can breath air is so incredible to me. And how it's just an adaptation for the poor oxygen levels in the betta fish's natural environment. Or other fish being able to do it to move from one body of water to another. Absolutely incredible.
Completely wrong there. Evolution is a lie, used by people, because they don't want to believe in God. I want you to know believing such a lie will not work.
A similar example is blood which I think evolved at least thrice.
We actually distinguish tortoises, turtles, and terrapins in the U.S. too. Although admittedly the latter is only referred to when we are speaking of a particular species. Maybe our scientists don't make these distinctions - but the ordinary person does. Really enjoy all your shows! You can't trust all KZhead videos on such subjects - but you bring all the current studies - including the ones that challenge each other. In other words, you don't just state "facts" (which may either be out of date or still under discussion) as so many "scientific" YT channels do - so I know I can trust you for the current information. Excellent work. Thank you. Enjoying your new backgrounds too.
Seconded. I haven't heard of terrapins before, but tortoises and turtles are different and not used interchangeably.
I have a pet tortoise and pretty much anytime someone sees him they call him a turtle. At least in my experience, people call anything that looks similar to that a turtle
turtle is the catchall phrase but when we need to actually specify we'll say tortoise or turtle or terrapin, at least in my area. for other places it might change as america is so large things tend to change from place to place.
@@offbeat4772 Not my experience where i live, though we dont really have turtles here but have tortoises.
In the infamous words of a great sage... "I like turtles"
Reject Crab! Embrace turtle!
1:45 we Americans use the 3 terms: Turtle, Tortoise, and Terrapin. Terrapin is kind of rarely used, though. Only when being technical, as terrapins are often called turtles for ease (but never tortoises).
Turtle it's use for terrain turtle? And tortoise for water turtle?
@@erilove593 the opposite
@@tosehoed123😂😂😂
that was super interesting! I'd love to see more about cases of convergent evolution for sure. Maybe "everytime things evolved into dolphins" (the bodyplan shows up a lot), everytime things evolved to have horns on their face, everytime things evolved into dogs (andrewsarchus looked a lot like a kind of canine but wasn't one; hyenas are not canines despite appearances; hyaenodon is also very dog-like in apperance despite not being a canine; and then there are thylacines ofc ... and those are just the ones i can come up with right now). Convergent evolution is so fascinating
Andrewsarchus wasn't at all dog/wolf-like like it is still time to time portrayed. It was a very close relative to the Entelodonts, aka the Killer Pig or Hell Pigs, who themselves, despite their name, were close relatives to Hippos and Cetacean (Whales and Dolphins) than Pigs. Andrewsarchus was firstly thought to be member of a group of hoofed dog-like animals, them once thought to be related to Cetacean, the Mesonyxian. Which was still believed by some people to be the case at the early 2000's, and hence why Andrewsarchus is depicted as a Mesonyxian, and as such as dog/wolf-like, in the BBC documentary "Walking With Beasts" in episode 2 "Whale Killer". An great obsolete image that still somewhat persist despite the new recent discoveries.
‘Trees’ is one example. Any homoplasy polyphyletic group will do. Also Dogs ‘copied’ andrewsarchus since andrew came first. The canines are the imposters 🤪
Technically plants dont have true ovaries since their ‘ovaries’ evolved completely independantly of ours. Alot of biology revolves around polyphyly. “True” is such an inaccurate word though. Who are we to say which taxon is the most authentic of the body plan?
@@dudotolivier6363 if dogs grew to the size of rhinos they would look like carnivorous hippos too.
@@lorencalfe6446 - "Dire Hippos"?
Having seen and handled a local small turtle here where I live for a very short time (I released it, did not want to cause it stress) I was fascinated by their structure. They are amazingly tough and strong even the small ones
Especially the small ones 😉 🐢
Absolutely you should do a post triassic turt evolution video!
I absolutely want to know more about turtles. They're so weird that they're amazing. And yes, I want to see other examples of convergent evolution. The Foosa looking like cats immediately came to mind.
Search up the marsupial lion
And lots of spiky, warm-blooded animals. 😂Hedgehogs, porcupines, echidnas, tenrec. Plus lots of other spiky animals.
@@passingby3584 I went down that rabbit hole a while ago. It was fascinating. Thylacoleo. Very cool.
@@teresaellis7062 those are cool all on their own, very interesting group.
Fossa are close cousins to cats, so that might not be convergent evolution. Now, the quolls are definitely an example of convergent evolution - they're small carnivorous marsupials that have often been called "marsupial cats" or "native cats".
Convergent evolution and parallel evolution have always been fascinating to me. I would love to see more videos like this one.
It's the only way we as multi celled organisms can avoid rent as we evolve. We got built in mobile homes.
"I cant wait to see what turns into a turtle next" made me question many things. Nice video, very enjoyment.
It’s not quite the same, but convergent technologies that were independently discovered by people around the world have always interested me. Like the bow and arrow, people all over the place figured out that one.
Or like swords. Europe and Japan developed different styles of swords of course, with European swords being more narrow tipped for stabbing through the gaps on thick plate armor, whereas Japanese swords were made more for cutting through thick wooden or light sectioned armor. Also because of the iron ore quality in Japan, they had to construct their swords a very certain way (by melting black sand in a furnace, and folding this several times over, after which they add a layer of carbon treated steel on top of it). But despite all of this, both styles utilize similar cutting techniques, parrying and fighting styles. There are differences but there are also alot of similarities.
The bow probably isn't convergent but is likely a very ancient development.
@@hedgehog3180 ancient doesn’t mean it was developed by one group. Multiple different groups discovered fire and simple tools without contacting each other.
Just FYI, we do, in fact, distinguish between turtles and tortoises here in America. That said, we just consider terrapins to be a type of turtle.
This channel is pure gold. Congratulations for the incredible research and keep up the amazing work. Thank you for inspiring me to keep on studying. You have earned a subscriber!
the convergence of sociality/eusociality in different groups would be cool, like how ants, bees, termites and naked mole rats have each evolved complex social societies
Ants, bees and termites are all descended from the same eusocial ancestor. Naked mole rats are the only other example of eusociality.
Co-worker: "Hey buddy, hope you had a good night off work. Get up to anything crazy?!?" Me, tomorrow morning, lying my face off: "Ya, totally"
Turtles and crabs are peak design.
Turtles and crabs, 2 bodyplans that have the most instances of convergent evolution.
I like turtles
Super interesting! I didn't actually know anything else evolved into a cheloniform body plan except the little Ankylosaur and the Armadillos! "Every Time Things Have Evolved Into Noodles/Worms/Snakes" would be super interesting, but also probably take a year to make and be 3 hours long lol
"when an animal becomes good at doing a certain thing, it often becomes copied by other lineages that end up doing that same thing. It's called convergent evolution." That's funny, I thought it was called plagiarism.
I love how many modern lizards have the same circle-like body of turtle ancestors, maybe if they change their lifestyle one day there'll be more turtles!
This is a certified 🐢 classic
Very clever idea for a video. And in a way, beetles are in the mix if you stand back far enough and think about it.
I often forget that all species (including us) aren’t done evolving, wondering what future animals will look like
I'd love to see a video on every time things evolved into tree
yes, but how often have turtles evolved into ninjas?
Turtles! I am excited for the not quite but totally almost turtles.
It's turtles all the way down, young man.
This is my first video of yours and I instantly subscribed!! Wonderful content and I love your stuffed turtle 😁
I am very supportive of more material on turtles. To meet sea turtles, especially to see them hatch, is to find them deeply compelling. I even helped to get two females back into the water safely. One was dragging herself back into the water over horribly sharp coral, and headed straight for a rock coral wall! The things we animals will do to propagate our species.
Just FYI, we call them turtles, terrafins and tortoises too. 😂 Or we simplify it by calling them box turtles, tortoises, sea turtles and river turtles to distinguish between the land based and aquatic. It makes it easier to know if they need water using this method. That's why you hear it said that way more often. It's for educational purposes for people who don't really care about turtles.
Today I learn about "You naughty saurus" 😂😂
I think a mention to aetosaurs could've fit the video. They're a less turtle like, but they're a lot more heavily armoured than modern day crocodiles, and they probably filled a similar niche as ankylosaurs and glyptodons
Its turtles all the way down
Thank you for this absolutely interesting, high quality episode! I enjoy all episodes, but this one sits defenetly in my favorite top 10 list! And YES please, I would love more episodes about convergent evolution!
Thank you I'm glad you enjoyed it so much! I'll definitely do more :)
I really just woke up then immediately sat and watched a half-hour deep dive on turtle evolution
so in the end all of us are 1 evolution away from being a turtle
Great video! I'd definitely love to see more on turtle evolution. One evolutionary question I've had is why are there no Testunididaes in Australia (there are some in Sulawasi that are across the Wallace Line)
I presume that turtles evolved in an area far away from Australia at a time when that continent had separated far away from the rest of the former Pangea. At this point there's no way for terrestrial turtles to migrate to Australia. But, are there at least sea turtles nesting on Australian shores today?
@@JohnDrummondPhoto Plenty of sea turtles in Australia.
Testinididaes are the terrestrial tortoises. I used the order name because freshwater turtles are typically called tortoises in Australia. My question is pertaining to the terrestrial Chelonians.
The fact that convergent evolution is described as "copying" is concerning to say the least.
Check out Horned Lizards, they’ve always reminded me of turtles, their skeletons look a lot like some of these examples of turtle convergence
Please do a convergence series! This is awesome!!!
I think you also have to look at plesiomorphic characteristics that predispose certain lineages to evolve a certain way. They’re not just evolving convergently in response to environmental pressures, they’re being funneled by their shared ancestral features. Like the animal you showed in your thumbnail is actually a stem-turtle that independently evolved derived turtle characters like a shell and oar-like flippers, probably because they had a bauplan that predisposed oar-like swimming styles and this then allows evolution of a shell since the thorax doesn’t need to undulate. Likewise other members of this stem turtle group like the pliosaurs shared this oared swimming style. And you can also mention how archosaurs repeatedly evolved bipedal predatory forms- unlike synapsids- and this is probably down to how the archosaur/reptile bauplan involved the tail in musculature used for the hind limbs, which synapsids didn’t so they remained mostly quadrupedal and often lost their tails. So “convergence” is only half the story.
@@Nelumbo_lutea Many quadrupedal synapsids lost their tails. This essentially didn't happen with reptiles, except maybe flying birds, and even they kept a functional pygostyle. That's the point.
The convergent phenomenon makes sense. Once there is a niche sorted out where heavier bones are an advantage, which could be ballast or could be protection from below giving value to a plastrum, they will be slower and the logic of survival pushes them towards a full-on armor tank. If you were designing combat vehicles, fast movers can have a thousand different shapes depending on expected terrain so long as you keep it light, but equipment which starts out heavy has one sensible way to go: shield it until it becomes its own garage.
This is a wonderful video. We have a pet tortoise, (a large male redfoot) who roams the house in diapers because he outgrew enclosures. We've had him for 12 years and love him - we've long had discussions about how different he is from other animals we've had in structure, being a turtle and all. This video answered a lot of questions we'd had for many years - thank you!!
Damn, evolution is just one big "I like turtles" meme.
Turtles are just a few steps before everything turns into crabs...
With gills…crabs. Lungs….turtles
It was sort of touched on with the phytosaur image near the beginning, but animals evolving the crocodile body plan/lifestyle would make for a cool video. I think the croc body plan evolved three or four times before actual crocodilians, including in what I think was the largest ever amphibian, Prionosuchus. Also, "saber teeth" have evolved so many times it's actually weird that there isn't some sort of saber toothed carnivore running around somewhere on Earth right now.
Seconded!
There are plenty of animals with "saber" teeth. Musk deer, elephants, walruses, baboons, etc....
@@fantasystaplesuwu1554 I think they meant predatory saber-tetth, but I was referring to the crocobods.

"I did warn you that turtle evolution was a path to madness" 9:40
I'm glad you included armadillos. This was very interesting and thorough. Thank you. Combining artist's imagination of how the fossils might have looked with actual pictures of fossils and without any clear delineation between the two, only confuses the presentation, in my opinion. Imagination of how things could look and the actual fossil records are both great, but need to be clearly defined when presenting a scientific case to people who may not be deep in the scientific field and/or realize how an artist is only giving their opinion of how the flesh around the fossils looked.
It probably could interesting to see just how many lineages evolved the feline body plan.
I mean I guess we could say the gorgonipsids did it first
Hey Ben! I’d love for you to make this a series. I came up with some content ideas I would love to see you cover: 1. Mimicry/convergent evolution in insects (example: the fossilized Oregramma illecebrosa vs modern owl butterfly 2. Convergent evolution in mammalian apex predators (Canidae, Thylacinidae, Feliformia/Hyaenidae) 3. Thylacosmilidae vs Felidae/Sabert-toothed cats 4. Evolution of carnivorism in plants, convergent evolution amongst pitcher plants (Nepenthaceae, Sarraceniaceae and Cephalotaceae) 5. Evolution of olfactory glomeruli (such as in neopteran insects and some molluscs but not all outgroups to these groups) 6. Electrogenisis in fish 7. Echolocation in bats and toothed whales 8. The multiple times syncytin genes have developed from endogenous retroviral elements on multiple occasions and independently in diverse mammalian species. 9. Old world and new world vultures 10. Evolution of venom in snakes, arthropods, platypus, etc. 11. Toxicity in animals derived from toxins in food source (such as poisonous feathers in birds such as the pitohui, ifrita bird, hoopoe, spur-winged goose, red warbler, etc). 12. Lobsters and scorpions 13. Symbiotic relationships between flowers/plants and insects/birds/other species. Sorry if there are any spelling mistakes, I typed this on the down-low as I’m supposed to be paying attention to a work meeting right now. 😅 Cheers, mate! Love your channel.
I think convergence on the rhino body plan would be interesting. Can feature brontotheres, arsiniotherium, and ceratopsians.
Tortoises are my favorite animal, I deeply appreciate ANY paleontology info on them 🙏this also confirmed that ankylosarus is my favorite dinosaur because it is the most turtle like xD
I am totally new to your channel but I really liked this video. Well-researched, not obscuring the details ir oversimplifying the complexities. All presented in a really captivating way. I'd definitely enjoy more videos of this sort in the future. As it is, this was an easy sub and a thumbs up from me. Great video! Also also, extra points for not omitting armadillos/glyptodonts. ❤👍
So what you're basically saying is the Tetrapod equivalent of 'evolve to crab' is 'evolve to turtle', right?
So shells are peak life then
This is truly immersive science and research. I imagined them alive in their habitats while you described them. What a fantastic world we live on.
This type of evolution also occurred with animals that turned into crabs. Both cases are absolutely mind-boggling to think about. It's amazing how much we still have yet to discover and learn about our world, our solar system, and beyond.
"This type of evolution also occurred with animals that turned into crabs" - what do you mean?
@@Dr.Ian-Plect Carcinization is a process where sea arthropods keep evolving the crab body plan.
@@hedgehog3180 Indeed, my aim is to get the answer, exactly as intended from the poster, though.
I know you usually cover animals on this channel, but I recently noticed that ferns, cycads and palms all have very similar morphologies, while being completely unrelated. I am really curious for an explanation as to why this 'body plan' works and if there are more examples. If the subject is too far from your expertise I would also gladly watch more turtle videos
There's also the way that "trees" have evolved separately many, many times.
Because its a plant. Similar body plan to do what plants do. And that is be immobile as a plant
@@reeyees50 dude, have you ever looked at grass and an oak? Or seqoia and moss? Just because the dont move they dont look the same. This is the same as saying that all vertebrates are similar because they have 4 limbs
I'm so grateful you spoke about the Glyptodonts. I'd heard a bit about them, and they captivated my imagination... But I'd never been able to properly visualize them.
I find it fascinating that so many body plans are so common during evolutionary history yet the human one is so far out!
Humans actually aren't that odd, fossils indicate that bipedalism was the ancestral trait of all apes however only humans and gibbons retained this trait while chimpanzees and gorrilas both independently evolved knuckle walking. So actually we're the normal ones while the other apes are weird, at least when it comes to walking, almost everything else about humans is super weird.
We see this in a typical backyard garden. How many things look like wasps but aren't
Strangely, I’m surprised by your statement that it’s American nomenclature that refers to turtles, tortoises and terrapins. As an American speaking with British speakers, they seem to always call them turtles whereas we Americans divide them up into turtles, tortoises and terrapins! Just my experience as someone who has been involved with turtles, terrapins and tortoises for the past 60 years…
