If you like this video, then you're going to love learning why snakes ARE lizards: kzbin.info/www/bejne/moizoouirdOen5I

[@1s23d]

How about pet crows or ravens that I have see people owning as pets?

[@rickh3714]

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 )

[@nerodia]

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.

[@epicexotics9698]

I think a african dwarf frog would be a cool video beacuse of how they are aquatic

[@ProfessorChaos56]

You should do a video on the Diamondback Water Snake.

[@Constantine_Cvl8]

Only one iconic phrase can sum this video up in a fast and simple manner. "I like turtles."

[@Needednose]

"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."

[@stefanostokatlidis4861]

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.

[@huntercollum869]

@@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

[@michaeltittel6718]

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!

[@Galian6686]

A gloriously haunting view that I have now learned. Thanks!

[@sashaanne703]

Dang! I just looked that up, and I kinda love it.

[@ReeveProductions]

Oh man, so true.

"... 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!

[@Stealthcoconut]

But we DO want to get you started on snakes! ^_^

[@ClintsReptiles]

You asked for it: kzbin.info/www/bejne/moizoouirdOen5I

[@hi_tech_reptiles]

@@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.

[@halaheleu7013]

Would need to skin one first and roast over a flaming fire till golden brown .

[@darthszarych5588]

I second this

[@sampagano205]

All the different families of iguanomorpha would be fun.

[@GaryDunion]

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.

[@VeryLastIfried]

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.

[@vando6679]

Yes agreed although I would love a video on the chelicerata group

[@johnathnheron1638]

100% agree, Would like a video on mammals though, especially cats and canines

[@YochevedDesigns]

Clint is the university professor we all wish we had, although we might consider switching his coffee to decaf. 😂

[@Androctonus84]

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!

[@ClintsReptiles]

Thank you for the help!

[@stefanostokatlidis4861]

Actually in my language those big words do mean something and most of the family names can be easily explained.

[@rasmusn.e.m1064]

Damn, this is how to criticize pronunciation. Well done!

[@Androctonus84]

@@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.

[@samuelstrausbaugh4476]

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

[@epicexotics9698]

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.

[@WolfieDawn]

Hey I came to say this! They are just stinkin rad!

[@Annie_Annie__]

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.

[@sampagano205]

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.

[@TrevsTreehouse]

Me too. I want a diamondback terrapin

[@PhinClio]

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!

[@stickmanblubbles4489]

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".

[@huntercollum869]

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

[@alveolate]

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

[@stickmanblubbles4489]

@@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.

[@Taylerlrox]

This has become one of my favorite series on KZbin!

[@sierrasicard4593]

Absolutely love the breakdown of information!! More videos like this please!! I love learning about the classification of animals and you make it great!

[@ohdarling6657]

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!

[@kngbnjmn]

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!!!

[@comfyfern8363]

So looking forward to the next episode in the series - especially birds!

[@pumpkinchow]

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 🙌.

[@sampagano205]

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.

[@Jackson-ex7em]

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!

[@tamb4185]

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.

[@lorrainemunoa791]

Marvelous, but I especially loved the bit in the bloopers going ALLLLLL the way back. That, Doctor, is impressive.

[@nopenahimgood.7719]

Absolutely loveeeeeeeed this! More videos like this please!!! The more knowledge of animals I gain the happier I become 😁

[@martenj94]

I can’t begin to tell you how much i enjoy and have use for these vids on phylogeny. Thank you guys so much.

[@malusignatius]

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.

[@stefanostokatlidis4861]

Probably they can’t tolerate submersion only in the early stages of incubation. Some Australian species can also do this.

[@SonicBoone56]

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

[@dshbwlto1]

What if you did an hour long video covering all reptiles and birds? I would definitely watch that

[@wilhelmtan5301]

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.

[@tayloryoung9455]

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!)

[@Jaybiiird]

That was so super cool thanks for doing that!! Seems more like a second channel thing, but I have no idea how that all works with the algorithm and I personally am all for it being on the main channel so more people see it. I truly love this channel so much. There's a chance Ill get to come out and visit the reptile room this summer which would be awesome sauce! Hope yall are well, I love your content so much keep up the great work!

[@Jijarugen]

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.

[@TicklePickles101]

I'll sit through any informative video you have! This is a much more fun way of learning and something easy to take notes on.

That was fantastic! Thank you for going through the cladistics!

[@jonathanshumpert9549]

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.

[@fishincheap1102]

This is one of my favorite videos ever. I want one of these for literally everything. And I’m not saying literally loosely like everyone else I mean every single type of reptile

[@KraftyKeelah]

What a fantastic video. Incredible amount of digestible information. Thanks for also putting in the weight and speed conversions too. That was a nice touch.

[@Tybold63]

Lovely and also appreciate the outro very much. As I appreciate plants too I wonder if there are any channel out there that addresses the "family trees" on a consistent basis about plants?

You did great I enjoy the video very much. I learned alot too. Thank u so much for sharing 🐢

[@brunobeltranbelmonte1081]

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 KZbinrs 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.

[@bramhorne7048]

I loved this! Please do more, I don’t even care what you pick.

[@LuckyStone888]

This really could benefit from at least 6 to as many as 14 videos. So many turtles not mentioned due to time contraints.

[@jadedjaws4952]

I actually have a sulcata, and it's hilarious how many people think that THAT automatically makes me an expert on turtles, resulting in an unwanted game of 20 questions. Next time imma just link them this video. Which was AMAZING btw! Just as another commenter said to the gecko families video, Clint has this way of explaining biology that I have struggled for years to understand. Turtles aren't nearly as complicated as geckos and their nightmare toes, but I did still learn a lot from this! Thank you!

[@gabr.7878]

More videos like this, and please go longer and more in detail if you can

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!
