If you like this video, then you're going to love learning why snakes ARE lizards: ruclips.net/video/dWPqXlxnki0/видео.html
How about pet crows or ravens that I have see people owning as pets?
1:16
Falla's skink?
( IF so- I've seen these at Hamilton Zoo, NZ. + minor sidenote my father knew the son of preeminent NZ ornithologist Dr Falla of whom it's named after )
How about a video on the colubrid snakes? Though I gather the cladistics aren't really settled on them, which makes it even more interesting to me.
I'd like to see the modern cladistic rundown on the group of snakes that were initially defined by not being vipers, boas, pythons or elapids.
I think a african dwarf frog would be a cool video beacuse of how they are aquatic
You should do a video on the Diamondback Water Snake.
But we DO want to get you started on snakes! ^_^
You asked for it: ruclips.net/video/dWPqXlxnki0/видео.html
@@ClintsReptiles MORE! lol we'd love a video like this but on snakes, or even a group of them like boas, pythons, Colubrids, etc and so forth.
Would need to skin one first and roast over a flaming fire till golden brown .
I second this
"Leatherback Sea Turtle, the BEST pet turtle?"
I can see it now...
"For upfront costs, we are giving the Leatherback Sea Turtle a -17 out of 5. The first thing you will need is your own private ocean, complete with its own beach, as well as a crane, truck, and trailer large enough to traslnsfer a 1 ton reptile there. Then there's the actual Turtle itself."
Actually they are impossible to keep in glass enclosures. The only way scientists have found to keep hatchlings either for study or for rehabilitation, is to tie them and suspend them in the middle of a tank without giving them the ability to hit the glass.
@@stefanostokatlidis4861 Man that's kind of messed up but it is so much funnier to imagine than it is messed up. I'm just picturing an eight foot long one ton turtle tethered to like a rock in the middle of an aquarium and good lord is it a funny image
surprised Clint didnt show us a good view down a leatherback seaturtles gullet. normally he doesnt skip any opportunity to leave us with some of natures finest nightmare fuel (while actually as harmless as can be), sporting a mischievous grin. as always, entertaining & informative video, keep it up!
A gloriously haunting view that I have now learned. Thanks!
Dang! I just looked that up, and I kinda love it.
Oh man, so true.
nightmaee fuel for jellyfish auhahaha
Oh yeah, I was waiting for that too! How could he skip nature's Sarlacc pit?!
I love this video. I've learned this in University but never so in depth for turtles down to family level. And the examples you provide make it so much easier to just learning names. I look forward to the next one. Ideally, we go through all the reptiles (including birds ofc) and then move to amphibians and if the series does really well the other vertebrates. I wouldn't really expect you to take the pain of going through arthropods... you could fill a channel with that.
Yes agreed although I would love a video on the chelicerata group
100% agree, Would like a video on mammals though, especially cats and canines
Clint is the university professor we all wish we had, although we might consider switching his coffee to decaf. 😂
"... turtles designed by a pair of 10 year-old boys waiting for the bus..." most educational quote ever!! On rare occasions I've encountered snappers crossing the road (and yep I did stop to safely help one cross a very busy road). More about skinks is always great content!
Only one iconic phrase can sum this video up in a fast and simple manner.
"I like turtles."
Small tip: "chelys" comes from the Greek word "khélūs", and as such should be pronounced with a hard 'k' sound as in "character" (which comes from the Greek word "kharaktēr") as opposed to a 'ch' sound as in "change".
And the c in Latin should have a hard K sound as well so probably a safe bet to hit the hard k whenever you see a c in a scientific name
hmm... this makes me wonder tho, do modern english speakers use classical greek/latin pronunciation at all? the one i seem to hear 50-50 on either side the most is probably 'bona fides' (monosyllabic 'faidz' vs latin 'FEE-deiz').
iirc, there's also a ton of greek+latin mishmashes in binomial nomenclature... on top of all the random non-english names for newly-discovered ones xD
@@alveolate I reckon it depends on the context. "Julius Caesar" for example is now pronounced completely different from its latin pronunciation, which would sound something more like "Yulios Kaiser". The 'c' in "science" is silent but the latin word it borrows from "scientia" pronounces the 'c' like a hard 'k'.
Edit: I wonder if greek originating English words have pronunciations closer to the original word than latin ones.
That was soo informative!
I really liked the indepth break down it helps you understand the differences without being overwhelmed with little details that normal individuals wouldn't understand or even recognize
All the different families of iguanomorpha would be fun.
Everyone struggles a bit with polysyllabic words they don't pronounce often. The only problem I have with your Greek and Latin pronunciations is using the English 'ch' sound instead of 'k' for ch, like normally in Greek and Latin based words, like chordate, archeology, chronometer, chrysalis, etc. A bit like nails on a blackboard for me.
Otherwise I have to say that as a biologist and huge reptile fan since I could crawl, I absolutely love your videos! Keep up the amazing work!
Thank you for the help!
Actually in my language those big words do mean something and most of the family names can be easily explained.
Damn, this is how to criticize pronunciation. Well done!
@@stefanostokatlidis4861 Yes, that's why I always insisted that my students learn Greek and Latin roots. Something like Pycnopodia helianthoides isn't as daunting to remember if you understand what it means, especially since it pretty well describes the animal.
I love this format! I also love that Clint gets so excited that he gets carried away with the Latin names and adds an extra "did" to most of the -didae's.
I love all your videos, but I loved this video because it is essentially a vastly more efficient and fun version of countless wikipedia dives that I've done. Please do frogs and toads (or, heck, all the amphibians) next!
Even though snapping turtles are amazing my favorite is the dimond back terrapin. The fact that they only live in brackish and it's blue is just fantastic.
Hey I came to say this! They are just stinkin rad!
That’s my favorite too.
At first they were my favorite because among local turtles in my area they’re the hardest to find (it’s easier to find 3 different species of sea turtles than diamondback terrapins), but now I love them for their own sake.
In addition to their environment and bluish coloring, I love their speckled skin and goofy smiling beaks and the amazing range of colors and patterns that their shells come in.
I always loved diamondback terrapins because I was always disappointed that there aren't a lot of really colorful reptiles around in new england. It's basically them and garter snakes. Since then I've also found their ecology super interesting.
Me too. I want a diamondback terrapin
Absolutely love the breakdown of information!! More videos like this please!! I love learning about the classification of animals and you make it great!
Honest I will likely own NONE of the animals you’ve had on this show, save children cause I like a challenge!
But I love learning about all the amazing things that animals do. I know that you’re a reptiles guy my favorite videos of yours are actually arthropods.
Please do this video for literally ever at taxonomy you can!
What a great video clint! I just loved the format (may even say i loved it even more that the pet videos!)... As i'm really a bird person i would find it amazing if the next video would be about the birds! My lil cockatiel would love to see how closely related he is to all these big strong birds!
On the genus scale, Egerniinae would be an interesting video since that includes so many species you've actually already made videos on. From monkey tailed Skinks to blue tongues to pink tongues to gidgees.
This is assuming that Scincidae is unworkable just on the basis of how skinks are the largest family of lizards and there's so many individual genera where there is basically nothing to say because we barely know anything about them.
Loved this video!! So much information and yet not overwhelming. A FANTASTIC video for science teachers. I am saving this one for myself to view again. Thank you for the work you put into this video.
Dude! This video is stinkin’ rad! I loved the format and all the information that you packed in, while still using common names and pictures and videos! So good! More please!!!
Absolutely loveeeeeeeed this! More videos like this please!!! The more knowledge of animals I gain the happier I become 😁
I have over 100 different reptiles and amphibians. I have 4 turtles 3 Florida snappers and one painted turtle. I’ve always loved turtles and had them since I was a kid. Snappers being one of my favorites. Great video bud and love the new format 🙌.
So looking forward to the next episode in the series - especially birds!
DO RAPTORS like eagles falcons hawks etc.
The other fun fact about the Pignosed Turtle is that their eggs are the only amniotic egg that can survive immersion in water, and indeed they need to be immersed in water to hatch.
*Edit, at least, that's what I've been told all through my studies... I've never read much about the Central American River Turtle, does it's entire nest remain intact when flooded without the eggs coming into contact with water, or does something else happen? If the eggs are immersed how do they respire whilst underwater?
If anyone knows, I'd love to find out.
Probably they can’t tolerate submersion only in the early stages of incubation. Some Australian species can also do this.
Damn, I'm in love with these very scientific videos of yours. More like this please! Obviously avian reptiles are something you should cover lol
i want to put a correction on 7:09 . That is a yellow side neck turtle, Podocnemis unifilis which is not from the family Geoemydidae. Other than that, the video is amazing. I am glad someone covered turtle taxonomy especially since yeah it is something not covered a lot by people.
What if you did an hour long video covering all reptiles and birds? I would definitely watch that
I’d love to learn about the Bufonidae!! The true toads are my favorite animals
Clint maybe you should do an african dwarf frog. They are amazing!
I like turtles but don't want an aquarium. A tiny Tortoise may be in my future like a Herman's Tort or something. A land turtle maybe? Idk. Especially ifI could build a nice big indoor enclosure for them. Thanks Clint! Love your vids and glad to see anything from you. Something like this on snakes, even a clade like boas (true and old world) or pythons etc would be neat, let alone snakes entirely.
land turtle, lol
A box turtle might be right up your alley
I do wish you'd covered the gopher tortoise. I had one who lived on my 5½ acre property when I lived in Mississippi. I didn't see him often but I damn near broke my ankle in one of his many burrows. My dogs harassed him one day but I pulled them away while my ex flipped him back upright and moved him closer to the burrow he was headed toward. He wasn't injured but after the stream of...poop? pee? maybe a mix? shot toward them, they decided they'd best leave the excreting rock alone! 😳🤦🏻♀️😂
speaking of turtle taxonomy, a new species of turtle was jusy discovered late last year called Mesoclemmys jurutiensis, which doesn't happen everyday.
About the pronunciation, you did really well for speaking in english, also you don't have to pronounce it perfectly since you wrote the name. Just a trick, If you know spanish, just think them in spanish, and the pronunciation will be almost a 100% correct, minus a few missed rules for latin pronunciation.
By the way, I love your content, I love all your videos, just as I love many other RUclipsrs videos, but, this is other thing, you are just the second content creator I have found in years, that explains taxonomy and phylogenetic trees so well and among those you are the best.
0:38 I thought the tortoise jumped out of his hand 🐢
Actually no modern diapsid has the two original holes. The lower temporal bar opened and closed throughout evolution.
I knew the Hidden neck turtle taxonomy differently.
First branched the see turtles, and then soft shells, snappers and mad and musk turtles where in one clade. Also the closest living relative to tortoises where the pond turtles, not the Eurasian pond turtles. When did this change? Also we have a common pond turtle in Europe, the so-called European pond turtle.
The only non-American member of the family that is considered to have travelled from North America to Europe around 20 million years ago. I am sure that if turtles were birds are mammals, each family would be a separate order now. Also it is a little sad that so many turtles are losing and whole families are losing too.
You show off that PhD Clint. I think you all are great. 👌🏿👍🏿 I love your channel.
"Don't get me started on the snakes." An educated threat as presented by Clint Laidlaw, a long time supporter of good humoured passive aggression.
😂
Some turtles have even been known to survive in the sewer, survive mutation due to toxins, and even learn ninjutsu!
Jokes aside, two questions:
1. How would sex determination due to temperature be an evolutionary advantage? It seems like it would lead to an abundance of one sex in areas with stable climates.
2. How/where on Earth did you get a tuatara skull?
This has become one of my favorite series on RUclips!
This is my new favorite video series! I really hope more are to come. Like some other comments said I feel like I learned more in less than 20 minutes with you than I did in college level courses. Thanks!
Curt, lets say that I would consider doing a bachelor in zoology (or biology if I cant find) do you have books you would recommend to read first?
I'm a lot into reptiles and animals,so my friends get suprise when I give the huge amount of information ☺️☺️😜❤️
"The Soft Shelled turtles have... wait for it.... (zoom) soft shells."
Me: Where's that Subscribe button.
Hey Clint can you make a video on the Australian barking geckos? There's not much information on them
PLEASE do this for snakes. It is so hard to get straight answers about snake phylogeny sometimes
oooh! Have you seen Gamera? It's a Kaiju (Japanese monster, like Godzilla (Gojira) movie about an insanely large turtle. I saw the newest one and it is SO amazingly good. If you love turtles, you'll love it.
I love your videos! Please do a video on Macaws. Would love to know your thoughts on them.
Yes!!!! One for the TURTLE NERDTLES!!! 🐢🐢🐢🐢🐢🐢🐢🐢🐢🐢🐢🐢🐢🐢
I love taxonomy! Next could we have one on dinosaurs, or pseudosuchia?
This video was so awesome! I love learning new things. I look forward to more videos like this one! I’d love to learn more about all of the reptiles (including the birds!)
How about varanus ? or just a video about black throated monitors and white throat monitors.
Clint Laidlaw is like Doctor Who meets mr. Ray from Finding Nemo 👌
Can you make a video with the Egyptian false cobra
Asking for a friend, What family are the teenage mutant ninja turtles in? 🐢
Could you check out the tomato frog? I think you would really like them!
flippin' brill.
that's how we bri'ish say "stinkin rad".
Can you do the rodents i always get them mixed up hope all of you are doing well
I've kept track/recorded all of the species I've seen in zoos/Aquariums, and I have seen 9 of the 14 turtle families, and 35 total species.
There is a park near where I live that has a freshwater aquarium. They used to have a large aligator snapping turtle named Frankenturtle. He had been injured and there were large staples used repair the wound to his head. He was one of my two favorite turtles they had. The other was the Mata-Mata. Seeing it catch fish was amazing, unless you were the fish. I find turtles in the road occasionally, mostly sliders, and luckily have a nice pond nearby to release them in.
kind of sad you didn't go in Tortoises more
Clint, man, I will be damned if I don't tell you what an impact your videos have had on me.
Not a patron now, but I will be as soon as I'm in a more comfortable financial situation. I have always had a certain level of respect for all animals and life, but through watching your videos and learning more and more incredible facts about them? It's like- a lot of people will look at a snake (or if not, something bigger like a crocodilian) and see nothing more than a mean, aggressive, killing machine. (Admitedly, I used to feel that way towards crocodilians). Not only have you taught me some incredible things about these animals, but you've helped me understand them and how they think. It makes me want to share my love for these beautiful and interesting creatures with everyone I possibly can. Thank you so much for the work you do.
Next: deep dive into African House snakes. Good luck.
Can you do arachnids leading to tarantulas! I’d love to know how closely related my tarantulas are to all the other arachnids!
Can you do a video on green Ameivas please
everyone on elden ring told me these were dogs?
Dude, the ch in chelidae, trionychidae, et cetera all are pronounced with the hard K sound.
In fact, if you want to get neoclassical names right, just err on the side of assuming ch is a hard K sound, unless you learn otherwise specifically.
This would solve your sole error that I noticed.
Sadly, this has so many "chel" in it, (all because kelone, romanized to chelone, means turtle/tortoise in classical Greek) so it kept happening.
And mispronouncing archelon.
AR-kelon.
I have since learned that. It makes many of these words WAY easier to pronounce 😅
@@ClintsReptiles Classical education FTW!
"What will you be explaining about Turtles..???"
.
Clint:
"..YES..👀"
.

Love this guy ..♥️😁👍🏼🙋🏻♂️
Goood morning Clint!
This was great and really interesting. Suprised that musk turtles aren't even close to terrapins, I assumed musk turtles WERE terrapins!
Please do salamanders
I literally wanted these kind of videos from SOME youtuber with actually education and I LOVED THIS!!!!!!
I LOVE SNAPPING TURTLES so much- I have created my •••OWN RUclips channel••• here devoted to the LOVE of COMMON & ALLIGATOR SNAPPING TURTLES!!lllll
Sadly, cannot tell you how many farmers & lake & pond owners I known throughout my life that HATE them even existing on their land!!! Other people around here are scared of them & equate Common Snapper to snakes that they ALSO hate!!! They KILL as many as they can find & catch!!
•••••If our reptile community here can save even A SINGLE turtle, it will be worth our while!!•••• 🙂🐉❤️
I'm a PhD student studying fossil turtles, this explanation is very well done!
I actually did a whole bone histology project based (initially) on something you said in your video about common snapping turtles: that their reduced plastron helps them walk upright. We had some snapping turtle bones in the lab so I cut them up to figure out when and how that reduction takes place in relationship to other bones- turns out it is a heterochromic mechanism but it happens in the egg- even hatchlings have a reduced plastron. So not really the outcome I "expected" but hey, that's science! 🧑🔬
A video on archosaurs would be cool, It would showcase the relationship between birds and crocodilians. The main issue is that the video would be very long, especially if one wanted to showcase some of the extinct groups for emphasis
Shout-out to Gus, the gopher tortoise that's been living at the Nova Scotia Museum of Natural History for at least 75 years now and is thought to be just over a century old. :)
FISH. FISH NEXT
(yes I know that cladistically there’s no such thing. THAT’S WHY FISH NEXT)
Video suggestion: Top 5 New Caledonian Geckos. Head to head, comparing Cresties, Gargoyles, Leachies, Saras, Trachs and Eurydactylodes.
I was thinking “I wonder what group that giant one from The Neverending Story would be in” and then I thought “it would be great if this guy would do a for-fun episode where he covers fantasy creatures and tries to figure out where they’d fit”.
If you did want to do something goofy like this, I’d be willing to do some 3D models for it if you want. I’ve already made a lot anyway.
It might sound silly, but as an old school D&D player, trust me, it’s the kind of silly that gets kids learning.
Marvelous, but I especially loved the bit in the bloopers going ALLLLLL the way back. That, Doctor, is impressive.
Hey Clint I went to the reptile room Monday and Friday. Sorry I had to leave early Friday but it was so fun and I had the chuckwalla hat. I SO RECOMMEND FOR EVERYONE TO GO THERE
I came across a common snapping turtle alongside a silt fence while doing an erosion control inspection at a construction site a year or so ago. A couple of weeks later I found egg shells in about the same location.
A few weeks later while walking the walk, I spotted a copperhead.
Thanks just the same, but that was too much variety for me.
I got to meet what I'm sure was a massive Alligator Snapping Turtle when I was a kid. I was walking along the riverbank & saw something strange in the grass & reeds. It was as tall as my mid-shins (almost to my knees, actually--I was a small kid) & the shell alone was at least three feet long & covered in rows of spiky scutes. Amazing thing, probably weighed more than 80 lbs at a guess. This was in Winnipeg, Manitoba, not a place known to have Alligator Snappers. I only learned years later that they sometimes get up to Minnesota, but only rarely. I suspect this one had come up the Red River via Mississippi tributaries, as several smaller rivers connect the Red to streams that come off the Mississippi, which begins in Minnesota.
I suspect the Alligator Snapper came up the Mississippi, took a turn through the tributaries & made her way to the Red (which forms part of Minnesota's border with North Dakota) & ended up in Winnipeg that spring. I think she was a female just because of her great size & was possibly there to lay eggs. If so, maybe there's a small population of Alligator Snappers in Manitoba, now. I was in awe of this huge critter & I just stood there & stared at her. She looked like a danged _dragon._ She didn't seem to notice me & I kept my distance.
You might have been told this since this, but in general, ch in scientific names makes a /k/ sound, like arachnid or Christian, even before e or i, like Achilles. When it doesn't it's usually because it's taking a word from another language, like Chinese, and just sticking the latin/greek word endings on it, which is common with for example recently discovered Chinese dinosaurs. But if you see y as a vowel elsewhere in the word, and it's got that cv-cv-cv kind of rhythm to each sub-word, or especially if it was named more than 20 years ago, it's probably a Greek chi.
Hey Clint, did you hear about the soft shelled turtle Steve Irwin discovered? I don’t remember the entire name but I do know part of the name has ‘Irwini’ in it. Love your channel 🇳🇿👏👏👏👏👏👏👏👏👏👏😊
7:15 I was Surprised! Tortoises ARE Turtles. I never corrected people because I didn't want to and NOW I don't have to. Thanks, This was a FUN video!
Solid video Clint!!! Quick.. well maybe not so quick question. Do we know if animals such as snakes or fish care that they are in captivity? If I get a ball python and put him in a bio active enclosure or even just a dark 40 gallon with a hide, WILL HE BE SAD? In my experience I’ve always said that goldfish don’t really care that whether they’re in a $1000 dollar tank or a filtered 2.5 gallon, but what if I’m wrong?
Advice: Words of Graeco-Roman origin used in English have loose conventions, so you don't have to say them the "correct" way in Latin or Ancient Greek (that would be rather absurd), however if you don't want to sound like an illiterate noob you should at least know one thing → ch = k.
Likely all those CH's are from Greek roots. You could also say Greaco-Latin, as they come to us through Latin. Greek has the letter chi - X χ, which in Ancient Greek represented the aspirated K-sound (as opposed to Κ κ, which was unaspirated), but by the time of the Roman conquest of Greece, the letter Chi had become a velar fricative, like German or Spanish , at least in Standard koine Greek. Neither sound existed in Latin, so Latin did not have letters to represent them. To write borrowed Greek words into Latin, the Roman's used a for chi (and similarly, PH for phi, and TH for theta). The sound pronounced became the same as Latin C or K.
Thus, when dealing with Greek derived roots, we likewise turn the digraph into our English /k/ sound. Languages such as German often use the more Greek sounding /x/ sound (velar fricative, German ), as they do have that phoneme and write it the same way too, but not so in English. Christ, chiton, archeology, technology. CH=K in Graeco-Latin words. However, since we have F-sounds and the TH-sound of Koine or Modern Greek, we do use those for Greek derived and words.
The only complication to this is that sometimes scientific names are not Gaeco-Roman, but use some eliemet of another language were could be like English CH, or like French CH, etc. Probably all the names you used in the video are such Greek derived words though (I dun wanna go check them all right now lol). If you're not sure in the future, if there's any confirmation that this is a Greek root, you'll know it's a /k/ sound.
Since you did ask for pronunciation tips... I will say that the -nychia suffix means "nails" (the Trionychia are the three-nailed turtles), and is pronounced "NICK-ee-ah".
10:54 Hey @ClintsReptiles you say the Leatherback is the largest non crocodilean reptiles in the (modern) world, but I could swear I've heard about species which grow upwards of 30 tons- hell, while there's a lot of moral issues around it, I'm pretty sure I rode on a 3 ton reptile at a circus as a kid- to my understanding it was a pretty common occurrence in the US. I don't THINK my parents put me on the back of a crocodile, but I'm not the biologist so I could be confused.
People educated in America call them all turtles but this is inaccurate...
Chelonians should be referred to in three separate categories, turtles have flippers and live in the sea, tortoise are digitigrade herbivores who live a terrestrial lifestyle and everything else is in fact a terrapin because it's an aquatic omnivore with claws on its plantigrade feet.
"testudine" should only refer to tortoise because it's well embedded in the Latin
Funny enough South Africans the UK and English-speaking Asia get it correct where as Americans and Australians normally butcher Chelonian nomenclature
I was deeeeep into some Jordan Peterson, all philosophical... then across the top "turtles". Did that say turtle families? 🐢 bye Dr. Peterson 😆
This was an amazing video
Great phylogenetic break down!! BTW… the Box Turtle is the most superior turtle, in comparison to your “snapping turtle” or “snipping turtle”….
Please, please, PLEASEE cover hedgehogs next! Theyre my favorite mammal
LOVE the last minute of the video about phylogeny and clade classification! (if I recall what I learned years ago correctly...)
its not a memory because I was too young to remember but my parents told me about it when I was younger, and still from time to time when talking about my nephews. Its a favorite story of mine to this day. When I was about 18 months old, I found a turtle while outside with my mom. I guess I was obsessed with it, and wanted my mom to catch it. She caved, caught it and put it in a box on the porch so I could look at it. My dad got home from work a little later that day. Asked what was in the box, and my mom was like "oh, your daughter found a turtle and was really interested in it, so I caught it and put it in the box so she could look at it." My dad looked in the box and said " hun, thats a snapping turtle!" It wasn't a big one, I guess about the size of my moms hand.
Fantastic presentation! 🍎
You just gave me a better education on turtles than i ever got in vet tech school, (and i was a good student). What next? Maybe Elapidae? Viperidae? I know they're only families, but I think the Colubridae alone would take hours to go over.
And where do you put Cotilozaurus? I remember some classification saying they're related to turtles, may be outdated.
Are you suggesting you'd be willing to make a video on all extant squamata (and, therefore, serpenta) families? Because I'd watch that, even if it ends up being 3 hours long I'd watch the whole thing.
There's a harry potter RUclips channel called the bakey, and she has a pet tortoise, but many people ask 'how's the turtle?' And she responds by saying "IT'S A TORTOISE!' And then rambles on saying that turtles are aquatic and tortoises are terrestrial. But that is complete nonsense, because not all turtles are aquatic
