Most People Are WRONG About Reptiles, And You Probably Are Too!


[Music] oh hi there I’m here with Gus Gus because we want to talk to you about what a reptile is and obviously what’s a reptile might seem like a very easy question but what is a reptile modern-day reptiles include things like lizards snakes turtles crocodilians and birds you heard me right birds are reptiles people often ask me things like if frogs and toads and salamanders are reptiles but they aren’t so what is a reptile let’s start with the things people often think make a reptile a reptile and see which of these actually pertain to reptiles as a group so one of the first things people often mention is that reptiles are cold-blooded and that is really a bit of a misnomer cold-blood I mean what makes blood cold you as a human keep your blood about 98.6 degrees but I know a lot of lizards that like to bask in a basking spot a lot hotter than that and can get their body temperature way over a hundred up to like 110 maybe even 120 degrees Fahrenheit you die at these temperatures just for the record that is hot blood but what people are usually referring to is what’s called ectotherm II which just means they get their heat to the thermi their heat from outside sources generally from the Sun that’s different from say humans which are endothermic and we get a little bit of heat from the Sun but most of the the energy that you use to keep your body at 98.6 degrees actually comes from the food that you eat whereas reptiles generally speaking generate very little heat in this way like I said most reptiles are ectothermic they get their heat from outside but most animals are ectothermic in fact pretty much all animals except for mammals and birds but birds one of the few endotherms in the whole world are reptiles gus-gus here being an Argentine black and white tegu is actually also a partially endothermic species they don’t do it all the time most of the time they get their heat from the Sun but during specific times of year they can use energy from food to warm their body up even before the Sun comes up for the day so they do have endothermy another example of this would be pythons like this ball python also show endothermy at specific times during their life specifically the females after they lay their eggs they actually coil around the eggs and they stay there with them until they hatch and all that time they’ll help keep those eggs the right temperature by shivering and that shivering uses energy from food the snake ate before she ever laid her eggs turns that energy into heat to keep the eggs warm and that’s also endothermic so obviously not all reptiles are ectothermic not all endotherms are reptiles and not all reptiles are ectotherms so it’s probably not the best thing to use to decide what is a reptile another thing people often say is that reptiles are slimy and these people have either never touched a reptile or they pulled it out of some slime because reptiles unlike mammals actually don’t have any glands in their skin which means they can’t make any kind of slime their skin is totally dry the inability to make slime is actually something that all reptiles have in common the next thing that people often say is that reptiles lay eggs it is true that many reptiles lay eggs we already mentioned that pythons like this ball python lay eggs but many do not like this boa for example most Boas give live birth as do a lot of other snakes such as rattlesnakes garter snakes and then lizards too like Blue Tongue skink as it turns out about 30% of all snakes give live birth and about 15% of all lizards so that’s a pretty significant number all crocodilians turtles and birds do lay eggs but they’re a heck of a lot of reptiles that don’t and there are some mammals that lay eggs you may be aware of animals like the duck-billed platypus or maybe the echidna these are monotremes and the monotremes are mammals but they lay eggs another thing that people often associate with reptiles are scales and it is true that reptiles have scales they’ve got scaly skin and this is almost universally true even birds have scales if you like on the feet of the chicken for example you’re gonna see a bunch of scales and as it turns out even feathers are just modified scales silk back bearded dragons and scale as ball pythons which this is not one but they do exist do show that scales can be lost actually pretty quickly so most reptiles have scales but it is possible to have an individual or even a whole species that doesn’t also you’ve noticed probably that fish have scales they are different in structure but it is clear that reptiles aren’t the only animals on the planet with scales reptiles have diapason skulls which plant me something you’ve never heard about before so let me explain a diapason skull is a skull that has on each side of it two holes behind the eye four muscles to pass through and it is true that the ancestor of all living reptiles had a diopside skull however these holes can be lost for example lizards have lost the bottom of one of these holes opening it up essentially in snakes they they have a kinetics color really flexible skull and those holes are basically impossible to identify because their whole skull is basically full of holes in Turtles the back part of both of these holes has been lost leaving both of them kind of wide open so you could make an argument that they don’t have any holes at all even though they totally do and it’s been so restructured in birds that there are no identifiable holes there at all so a lot of living reptiles don’t have a die opsins go like this but there Esther certainly did therefore if it has a diopside skull reptiles are the only ones that have that so it’s definitely a reptile if it had of the diopside skull but if it doesn’t have one it still could be a reptile the one thing that truly unifies all living reptiles is they do share a more recent common ancestor with all of the other reptiles than they do with any other animals on earth and that truly is the thing that unifies them as a group they are more closely related to one another than they are to any other living thing this is why birds must be included in this group birds are the only living descendants of the dinosaurs crocodilians are more closely related to dinosaurs and therefore birds than they are to any other living group of reptiles except maybe the turtles we really don’t know where they go you can’t make a reptile group with crocodilians lizards snakes and turtles without including the birds because they’re uptight and interestingly reptiles share a more recent common ancestor with mammals like you than they do with amphibians like frogs and toads and salamanders so those things are not reptiles if they were you’d be a reptile too so to reiterate reptiles share a more recent common ancestor with all of the other reptiles than they do with any other living thing they are the descendants of animals with diopside skulls and many of them still have them they generally have scales they may or may not lay eggs they don’t produce any slime they may or may not be ectothermic cold-blooded and now you know and as always like and subscribe let us know if this is the kind of thing you’d like to see from us in the future we would love to share all kinds of cool facts about reptiles if that’s the kind of thing you’d like to see so please let us know down in the comments make sure you click the little bell so you’ll know when all of our future videos come out and we hope to see you real soon and come again we hope cereal said dang it snakes and snakes also snakes snakes and turtles and if you’re frustrated by the fact that I’m holding a tortoise we got a whole video for you to watch turtle turtle thanks Houdini it’s really bright she just picked right what is it the family good dinosaur good punch here toes that okay good dinosaur fans sorry birds or reptiles hand fans

    I never, in a million years, would have thought that there was be so many die-hard defenders of Linnaean taxonomy out there when I made this video. But I was wrong. I haven't been cussed out so much since I told you that iguanas generally make bad pets 🙂

    So, just so you know, humans like to organize things into categories. In the mid 1700s, Carl Linnaeus proposed one system for categorizing living things based on observable similarities. It was a useful system, but it had its limitations. Namely, organisms were grouped based on known attributes. If you knew that an organism went in a specific category, that didn't teach you anything about that organism that you didn't already know about it when you put it in that category in the first place. In other words, it was useful for organizing information, but totally uninformative.

    We have learned a lot since the mid 1700s. One thing we have learned is that living organisms are related to one another because they share ancestry with one another. Phylogentic analysis allows us to understand these family relationships better. Organism that share a common ancestor tend to share many attributes that they collectively inherited from their shared ancestors. This means that if we know where an organism fits into the tree of life, then we suddenly know an amazing amount about it even if we previously knew nothing. It is a vastly more useful way of classifying organisms.

    But given that many of the Linnean names have been used for centuries now, we are trying to fix a lot of the categories to be relevant given what we now know about shared ancestry. The only good kind of a group includes an ancestor and all of its descendants. All modern reptiles share a common ancestor, but they also share that ancestor with birds. If we are going to use the term "reptiles", then we have two options: we can either include birds, or we can accept that it is a garbage group. I prefer the former 🙂

    Hopefully this helps.

  2. Viperion says:

    So, technically, if dimetrodon had 2 holes behind it's eye socket, mammals could be classified as reptiles?!Just because it was technically a mammal ancestor.

  3. TheOrangeNinja says:

    Heeeyyyyyyyyy, someone understands how monopheletic clades works! I love it! I prefer "diapsids" as a general description for the group containing all animals traditionally identified as reptiles, as well as birds.

  4. Logan Kordinak says:

    Interestingly the scutes on a birds legs are actually feathers that evilved into hard scale like coverings. So scales became feathers and then the feathers became scutes

  5. Storn Olson says:

    ayyy great vid Clint. I like the scientific aspect of these ones. And Im sorry anyones cussed you out. I can tell youre a nice guy

  6. Lord Bolton says:

    2:55 Shivering to generate heat isn't endothermy. Every animal generates heat from movement and digestion, but that isn't endothermy.

    Are bats reptiles

  8. Kluleess says:

    I learned a few new things today, very cool. TY

  9. David Baldock says:

    Exactly. Birds/dinosaurs and crocodiles are both Archosaurs while lizards, snakes, and tuataras are Lepidosaurs. Both Archosaurs and Lepidosaurs are diapsids.

    I knew it! People look at me weird when u say birds are reptiles. I came to the conclusion on my own, and its as smart as I really get. I've peaked, people, I'm a genius in an incredibly specific way

  16. Paula says:

    If I ever get the suitable environment for it, I want my own "Gus Gus"! I adore him and your channel. I trust any content that you put out will be awesome. I love your boa and I have a normal BCI of my own named Merlot.

    More of this…please.

  18. The Great Wolf says:

    We're all reptiles from synaspids to today
    We're all dinosaurs!

  19. Case D says:

    I could see how people might group birds with reptiles. However, in my opinion grouping birds and reptiles together isn’t the way it should be. Animals are classified in two ways, the Linnaean and phylogenetic systems. The Linnaean system groups animals based on characteristics, regardless of their “ancestry.” The phylogenetic is the other way around, grouping them based on ancestry . Personal preference here, I prefer the Linnaean system because to me it makes more sense to group animals together based on characteristics. To me, birds are better off in their own category of animal and same goes with reptiles even if scientists say they are archosaurs along with Dino’s and pterosaurs. Another thing, if we were to classify birds with reptiles wouldn’t we have to include mammals in that category since technically, scientists say that mammals have reptilian ancestry as well? One more thing when you say “feathers are modified scales.” Mammals hair, birds feathers, and reptiles scales are all made of keratin, and even the hair that we grow on our heads and on our body’s is made of keratin. Why? I don’t know. I guess that’s just the way God made us. But, Clint I do respect your right to your own opinion and I am actually a fan of your channel. Keep up the good work.?

  20. Nicholas Lienandjaja says:

    I remember this from my Biology class. Here are types of reptiles I remember:
    Turtles and tortoises
    Lizards, snakes, and mosasaurs
    Crocodilians
    Tuatara
    Ichthyosaurs
    Plesiosaurs and pliosaurs
    Dinosaurs (including birds. That's right, birds are living dinosaurs)

  21. G LaP says:

    I would enjoy it if you made a video explaining how breeders classify reptiles by age, if you know, i cant find a good or consistent answer anywhere. What i mean is, when i purchase reptiles from online breeders i get options of "hatchling, baby, well-started baby, juvenile, young, small, medium, large, adult, and sometimes even others, how are these classified? How many months old does a lizard or snake have to be to be a juvenile, or a well started baby? Thank you btw all of your videos are awesome!

  22. iParaShane says:

    Birds are not reptiles as they are both classes

  23. Deda Mraz says:

    Birds arent reptiles

  24. Ryan Schneider says:

    So how are birds just not the newest category of Animalia? what you described in this video distinctly shows a difference between the two.

  25. Daniel O'Brien says:

    Yes yes yes more biology and zoology please good sir ?

    Clint you forgot a group…a very ANCIENT group… Tuataras

  32. Carly Philpott says:

    What makes amphibians amphibians?

    You have to make a video on that!

    What's funny is that I've had reptiles since I was seven, and I didn't know 75% of the facts you presented. Every time someone asks me what a reptile is, I will use this video.

  33. Know Face says:

    Wait, does this mean that he’s going to do bird videos? ?

    Gus gus sideeying us as Clint talked about humans being the slimy ones ?

  35. Amber Rae Dawn Tollenaar says:

    This is gold. THIS is the reason I watch YouTube. I love go learn about the natural world, and this is thw first time in quite some time that I've felt like I learned something major about reptiles as opposed to superficial things like morphs other aesthetic. This is beautiful, I'm so glad I found your channel. ❤ #KnowledgeNotHate #RespectNotFear #ReptilesAreBeautiful

  48. Vesmir789 says:

    Love the video! Your final argument feels like a bit of a cop-out lol, but in a funny way because it's also true. Being closely related, from a genetic perspective, is generally the best way to determine what animals belong in what groups. It just doesn't do much to help if you pick up an animal in the wild and want to know if it's a reptile or not 😛

    Your video does highlight a great point though: as with almost everything in biology, it's kinda impossible to make "rules" and specific definitions because there are ALWAYS exceptions, which I somehow love. Another thing I love about biology is that some of the things we haven't figured out yet can be pretty shocking to think about. For example, we still don't have a universally accepted definition of a species, or even a definition of life!

    Yes ! love this kind of content! The chicken is RAD….! Enjoy how you inform and educate us —for all ages– thank you….Clint and your crew….

  51. Carrie Seymour says:

    I have to disagree that it's not sometimes useful to have a label to describe a group that's not monophyletic. Like, "simians which are not apes" is a grouping that tells you something about the organisms and their relationships.
    In my personal opinion it's probably more helpful to have a label like "monkey" for that than to re-purpose a name that's meant that for a very long time and is recognised (more or less) by most people, even non-scientists, as meaning that, to mean something different, all while not having a label shorter than "simians which are not apes" for that group. (As amusing is it is to say that we're all monkeys, and so is the Librarian of Unseen University – can you smell banan-.)
    Even in the case of groups that really don't tell you anything more than characteristics you can just observe, you still sometimes want to refer to the collection of organisms that have that characteristic, and I don't think it's wrong to have language to describe it.
    I just don't think cladistics play very well with traditional Linnaean groupings and it's more confusing than clarifying to try and repurpose the name of a Linnaean category to a monophyletic group that must necessarily either exclude large swathes of the traditional category or include a whole lot of other stuff that's in a different traditional Linnaean category. I'm not saying we shouldn't have a name for the descendants of the last common ancestor of everything traditionally considered a reptile, but I don't think reptile is the best name for it.
    Frankly, I try to avoid the use of the word because I don't even know what definition of it I prefer, let alone whether any given person I say it to is thinking of the same thing when they hear it.

  54. OGG SOngZ says:

    Humans sre synapsides and synapsides are like the cousins of sauropsides(encester of all reptiles and birds). The first synapsides and the first sauropsides are lizard looking so we came from some reptile looking animals.

    ''Moooooooom, can I get a dinosaur as a pet?''

  58. jpfan1989 says:

    I take it that when you use Reptile in a broad term such as this, that you are referring to Archosauria the group that houses Snakes, Lizards, Turtles, Crocodilians as well as Avian and Non-Avian Dinosaurs.

    Personally I would be a little hesitant to call dinosaurs (and subsequentially birds) reptiles seeing as it is believed that dinosaurs broke off from true reptiles sometime in the Triassic Period.

  59. Stacey Weatherby says:

    Very informative! Learned more than a few new things! People like to put everything (and everyone!) into nice neat groups however in reality, it’s all about blurred lines and shades of grey. Especially in nature! ?

  60. Song of Shadow says:

    What if I don't believe that evolution is true? Since birds and reptiles do not in fact share a common ancestor, but a common Creator, you cannot use that as a basis for what something /is/.

  61. lucas lamb says:

    I know it makes sense in a way but just no u cant add birds to reptiles if you really wanna talk about the whole idea of a specie is flawed

  62. mutts luv says:

    What morph of ball python is that. I've never seen a morph like that

  63. Xelloss Dio says:

    In that case, if sharing a common ancestor is the way to put organism in specific category. Then all reptile are amphibians, and mammals are reptiles, and fishes are amphibians. Soooooo human is a fish, buahahaha ;D Really … Or maybe birds are – birds (or if you insist, dinosaurs ;P). LOL hyhyhy Greetings =]

  64. Anzu Wylei, Just a dino guy says:

    But are mammals and reptiles amphibians ?

  65. Donna Marie says:

    I've heard that crocodilians are not reptiles, but instead should be their own separate class

  66. Josh The Weirdo says:

    Please do a video on chickens as pets. ?

  67. Chris Chesna says:

    Birds are birds. They are their own class of animal, even if they were related in some way.

    This was a topic that nearly got me assaulted when I worked at como zoo when working at the reptile and avian tables

  69. Jean Scuissiato says:

    If people get crazy when science shows that birds are dinosaurs, imagine what they will think when they learn we are fish.

    Incredible video, thanks for that!

    Yeah that’s a yes from me chief

  71. Stefan Enslin says:

    I couldn't find a similar question, so I will ask: I have always been under the impression that birds bones were more hollow than snakes, lizards and dinosaurs. Am I wrong?

  72. Shelby Ana Abbott says:

    Are fish reptiles?

  73. James Thompson says:

    Great video not sure how I missed it.

    Wait! Birds are reptiles! Now, I have many, many reptiles! About as much as you and snake discovery, I Raise many chicks and pigeons! ??

  77. Stormy Tanuki says:

    I have a question. Since birds are reptiles, how come they're a separate class in biology? Like birds are in Ornithology, but not in Herpetology like reptiles? Shouldn't they be included in herpetology too?

  78. BEANS says:

    I actually never knew anyone thought that reptiles are slimy. Interesting

  82. Yvonne Rogers says:

    Boy, that was really darn interesting! Thanks! I knew some of the information you shared before watching, but it hadn’t clicked for me that it’s common ancestry, not any one attribute, that makes reptiles reptiles. Wow. They say it’s a small world, but if you pay attention, it’s still really big. Best.

  83. seanh70 says:

    Love this channel, Clint!  Don't agree with you on the matter of the chicken thing, but, makes no difference.  It doesn't change the way that I think about you or this channel.  I just ignore that part and continue to learn about all the other stuff you teach.  So its all good.  Keep up the great work!

  84. Predatoreus Films says:

    Well, dinosaurs split from reptile like creatures in the late Permian period, and birds are the modern day descents of the dinosaurs, so I guess you can connect them like that

  85. Logan Donaldson says:

    Dude.. I don't know what qualifications you have compared to me.. But birds are NOT reptiles

  86. Chris S says:

    I mean wouldn’t we be considered reptiles since our skin has separate plates, and isn’t hair just modified scales like feathers are on a bird.

  87. Nikki Ruiz says:

    OMG! I loved learning this! So interesting to learn about something I was probably taught in highschool and that information that has now evolved just like the reptiles I love so much!! Moree videos like this will be most enjoyed! Thanks!

  88. Nikki Ruiz says:

    Also! Now I am super curious. Was I taught the linneanan taxonomy system in highschool and now that is NOT being taught in biology?

  93. L Squared says:

    Phylogenetically speaking and even anatomically speaking, birds and reptiles are so much more similar than people realize

  94. Mantaris Cheap Loser says:

    When my professor told the class that birds are reptiles he made it like it was him against the world.

  95. Asp the Wyvern says:

    'Reptile' doesn't mean anything in taxonomy anymore, so the only definition we have to go on is the one used by most people, which specifically excludes birds. Even though birds are descended from the common ancestor of all reptiles, birds aren't reptiles.
    'Fish' is similarly useless in modern taxonomy. Tetrapods are not fish, despite being descendants of the common ancestor of all fish.

  96. poormans bicycles says:

    So thats why the velociraptor had feathers in Jurassic park 3

  97. Bryan Yorke says:

    We all must remember that evolution is still just a "theory….." Darwins theory of evolution in the book titled "on the origin of species by means of natural selection and the preservation of favored races in the struggle for life." Carbon dating is scientifically inaccurate as proven dozens of times, and the fossil record in layers of sediment is inaccurate for determining age as well. Check the vertical petrified forests which proves this inaccuracy. The big bang, also a theory. No proof, yet like evolution, is taught as fact. Things like the human eye, dna cannot be explained by evolution/natural selection.

  98. Eric Remington says:

    I'm a simple man, I see Tegu I click Tegu

  99. Majster says:

    Maybe episode about synapsids aka "mammal – like reptiles" (outdated, but popular term)? It's interesting that we are still synapsids just like birds are still reptiles.
