Henry the tuatara is over 120 years old, and is still living and reproducing in invercargills museum pyramid, new zealands most successful tuatara preservational breeding sanctuary. sadly due to the buildings lack of earthquakeproof structure it has been closed down and will require over $20, 000,000nz to upgrade to new standards. 😓
Raising Tuatara in captivity will indeed help the population, it’s a effective method that has saved other endangered animals like the bald eagle, giant panda, and etc. from extinction. If we caused it, we can fix it.
Why can't they be raised in captivity to eat rats? They are large enough, and they are carnivores... they should feed them beetles, lizards, birds, and rats. Then they could reclaim their territory. And, well, they will have good food supply. Rats are quite hard to get rid of.
The Permian extinction left many open niches with little to no competition resulting in the impressive diversification of species during the Triassic... similar to literally all other extinction events. It's bizarre but it happens.
@@milesarcher8502 A bloody lot of them have gone extinct because of the human race over the last 100, 000 years though. So much so that it is often referred to as the 6th great mass extinction.

Once you said it wasn't a lizard I must admit I thought the legs looked a little thick in comparison to lizards. Is that a differentiation or is it just me?
It might be, I'm not sure, although it could just be the angles of the photos perhaps. Depends what lizards you're comparing too I suppose, Monitor Lizards would have much thicker legs than a tuatara.
We know nothing, for all we know it could secretly be evolving a new power to evolve into ultra evolution creature to evolve into the reincarnation of DINOSAURS TO FIGHT MAN... and probably fail to our technology...
New Zealand is working to eradicate invasive mammals from more islands and fenced off areas so the amount of suitable tuatara habitat is increasing over time
The devs will work it out. Though they haven't been the best at balancing the game. I mean look at humans. Humans have changed how every server works, and they even added the urban biomes to the game.
Maybe I've got this wrong, but it's my understanding that some epigenetic DNA changes can be passed on to offspring. So if the Tuatara take longer to mature, would that mean they pass along more epigenetic DNA, and thus mature faster?
No; theoretically, this might ratger yield somewhat better adopted offspring (assuming same mechanism in reptiles as in mammals, whose epigenetics I've studied).
I remember discovering this wonderful creature when I was about 10, and spent more than a half-century pursuing my fascination for relict species. Thank you for a welcome update to a very old passion.
Have you also heard of the blue anole another extremely rare reptile Though because of the rarity breeders are normally just breeding them with common green and Know though because of how rare they are breeders are normally just breeding them with common green anoles
And that’s why I love being a New Zealander, being able to have one the last members of the dinosaur family, btw excellent video most people from other countries get all the facts and names wrong but you got them all right!
Excellent video. I live in Invercargill where the breeding program was pioneered and getting to see these guys was the main reason meusum visits were so exciting as a kid. I grew up learning that there was two species, but after watching this, and then some googling, turns out you're now correct. Gene studies in the 2000's revealed that the two species were just a single geographically separated species. You learn something every day!
I consider myself incredibly fortunate to have seen tuatara in the wild at the wildlife sanctuary just outside wellington - they were young, so were much smaller than i was expecting, but even seeing one was so magical! The nz department of conservation has helped save so many of our unique animals here, not just tuatara, but kiwi, takahe, kakapo, and so many more have been brought back from the brink by breeding programs and rat-free sanctuaries. When you travel here from overseas, customs is incredibly strict about perishable items brought over, because our fauna and flora were so isolated for such a long period of time, and pests or diseases brought over could decimate our precious natives, like rats and dogs did in the past
I would recommend visiting Zealandia in Wellington (my hometown) in New Zealand. There are plenty of Tuatara now living in the sanctuary and are almost garunteed everytime to see one.
The Tuatara is a remarkable animal indeed. It’s great that you make a video of this animal and include the danger of it becoming extinct due to human actions. I hope that by watching this video more people will become aware of the pressure that is caused on nature by humans. Thanks so much.
He's so cute, wish I could have a breeding pair of them to increase the number of them as well to help out as I already have been a reptile breeder for over 20yrs wit iguanas and others!
These guys are one of my favorite reptiles - as a biology/herpetology student, I would love to be able to see one in person, or even work with them in the future to support the conservation.
I kinda want one as a pet. But maybe they're not so great for that, especially since they breed slowly. Maybe once we learn more about breeding and keeping them in captivity and their population recovers some we could have them in home terrariums someday. Reptiles are severely underrated pets imo.
Tuatara are similar to Tortoises in the way that they live for a very long time and reach maturity later in life. Which is why Tortoises are not the most common pet Reptile.
I live in Invercargill where they're breed in captivity. I know what you mean about wanting one as a pet, but honestly they move about so little most of the time you'd get more interaction from a tautara statue than a live one.
they seem like they would be a cool pet, the only problem i see is that they can live a really long time, especially in captivity. i'd worry that they would outlive their owners! but other than that they seem chill lol
It's nice to see our little lizard pop up time to time I'm a New Zealander and I've only seen 2 tuatara in my life in person and it was in the wellington zoo lol
It looks like what I imagine some dinosaurs to look like... The head and jaws anyway. Gorgeous animals, and great video! The third eye is so strange!!!
For all the years I have owned lizards, I've caught them, looked for them and bread them. I do believe that the third eye they posses is used for detecting predators. But it is designed in a way where it picks up light or (shadows). For instance a bird flying over head casts a shadow. I consider it early warning alarm system. When it detects changes in the light spectrum it sends electrical signals to the brain sending a message to run, look up or freeze. I have seen this happen multiple times with my bearded dragons and iguanas. From either planes flying over head, waving my hand, or even birds flying over head. That's my guess at least, from observation. . .
When I was a little kid I learned a lot about animals. The Tuatara was actually my favorite, because of its unique differences. Thank you for making this video👍
4:20 I agree, it is pretty strange that Amphisbaenians are legless. Not that Snakes are, Or that Slow Worms or the creatively named Snake-Lizards are, Only Amphisbaenians' leglessness is strange.
Really well presented. Tuataras turn out to be more interesting than thought. I never thought much of them or their evolutionary history until now - they were more of the weird little cousins that are otherwise dull. Again, great conveying of information. One little gripe though - shouldn't the crown group at 4:47 be Sauropsida, not Reptilia? Reptiles are paraphyletic.
Thank you! And do you mean that Reptiles are paraphyletic when birds are included? Or is there another group I'm forgetting? I probably should have noted that I meant the crown group Reptilia and not the stem group.
No, I meant they are paraphyletic under most uses, but I guess since you didn't exclude birds explicitly, then they aren't technically paraphyletic in that case. Still, isn't there already the name of Sauropsida (or is it Diapsida?, turtles are a bit of a conundrum, if memory serves me well) to refer to the whole clade uniting lepidosauromorpha and archosauromorpha?
Yes, I think both Sauropsida and Diapsida include lepidosauromorphs and archosauromorphs, but for the sake of simplification I thought it would be best to just have it labelled as Reptilia. And yes turtle phylogeny is a fairly controversial topic, though apparently there's good evidence to support their placement in a sister clade to archosauromorphs.
Hi Ben, thanks heaps for making an accessible and interesting video about our native taonga. I happened to be there at the release of the first tuatara into the sanctuary in Wellington, now known as Zealandia. There is really nothing like them, even though their appearance is so lizard-like, there's so much more to them as a natural phenomenon.
I recently watched a short video documentary about the project at Wellington to remove rats from the area! They're doing a lot for restoring their native ecosystem; it's really cool!
Beautifully made video. This is a very comprehensive report on this animal I have never heard of. Please keep this sort of research up, you seem to go very in depth, and it is very wonderful to see such interest and passion in researching something like this. Best of luck on TH-cam!
I definitely just learned something new! I didn't even know these creatures existed! So interesting!!! Thank you for taking the time bring awareness to many lesser known species.. Especially those who are threatened.
How come when describing different animal groups birds generally appear by themselves alongside mammals, amphibians, and reptiles when they're actually dinosaurs which are reptiles?
Reptiles are usually defined paraphyletically, meaning that it excludes birds, even though it should include them to make the group monophyletic. So in a scientific definition, birds are classified as reptiles, but there seems to be a lot of confusion when you try to tell people this.
I think some people DO argue that they should be reptiles, but all groups evolved from another (invertebrates-fish, fish-amphibians, amphibians-reptiles, and reptiles-birds/mammals). I think true birds arrived not long after true mammals in the Jurassic, and I don't think *any reptiles are warm-blooded like them. *I think some Dinosaurs were warm blooded, but I tend to think of Dinosaurs as the bird version of mammal-like reptiles (Cynodont, Dimetrodon, Gorgonopsid, ect.). Not quite reptiles or birds, but somewhere in-between with features of both.
Excellent video as always Mr. Thomas, and a great subject to boot. I knew a zoologist as a kid who had a tuatara about 60 or so years old he would occasionally use for outreach, it was a real fucking dinosaur! Easily the coolest animal in his care, and he had blue tongued skinks and a new guinea singing wild dog.
Great video! One amphisbaenian genus (bipes) actually retains the front limbs. Also, I would think about them as lizards generally because they are not as highly derived as snakes are.
Ah yes, I probably should have said mostly legless. And lizard is usually used in a paraphyletic sense, excluding snakes and amphisbaenians, but I guess you could probably group them in if you wanted to make lizards monophyletic.
I first learned about the tuatara from a very unlikely source; an encyclopedia from 1916 that I had bought at an antique book store near my home. Ever since then I have been fascinated by this remarkable animal.
A third eye may be for detecting objects above the head. Like a certain type of blindness in humans, it allows the brain to detect obstacles around them, but sends no information to parts of the brain that allow the individual to perceive sight.
This is a very interesting and educational video. I've read a little about the tuatara and its 3rd eye before, but, never saw a picture of the eye. I also never understood the differences between them and lizards before. Thanks!
Not sure why such emphasis is placed on the "third eye" it is present in dozens of species if not more and is not exclusive to reptiles or amphibians, yet your title "The Lonely, 3-Eyed Reptile" implies it's a special characteristic of the Tuatara. Kinda click-baity if ya ask me.
As a child, 45 years ago, I remember going to see tuatara at the Southland Museum in Invercargill the southernmost city in New Zealand. Only one other city in Chile is further south than Invercargill.
And he really understates the lifespan in the video. Henry the tuatara made the news by becoming a first time father at 111. That was over 10 years ago and he's now around 121 years old. Some experts believe tuataras may live as long as 200 years.
Bearded dragons have that "3rd eye" on the top of the head and it is light/dark sensitive and is useful in detecting and evading aerial predators that would prey on them. Tuatara are amazing reptiles. Captive breeding and raising is an effective method of conservation, the Crested Gecko is a great example of that.
I watched a neuro science podcast that discusses this. It is actually an exposed part of the brain. We have one as well but it is located near the center of our brain and is used to produce melatonin and other hormones involved with sleep.
So cool to think that the laat remnant of this Mesozoic group of reptiles survived on one of the most remote landmasses on Earth. It's like finding a mini Skull Island.
4:37 That, is not a dinosaur, it's a modern bird, called a cassowary. That third eye might be there to help them orient themselves according to the sun. Honey bees have 5 eyes, 2 main large ones for seeing details, and 3 small ones on the very top of their head. These are used to orient themselves to the sun and they use that information to help them navigate to new food sources and to find their way home.
@Bring peter griffin to Super Smash bros They evolved from dinos, yes. However, they are different now. They're not fully dinosaurs any more, close, but not the same. Just as we evolved from apes, but we are not apes any more. We can be considered primates, but we are not apes, just as apes are not monkeys any more. Birds are now their own sort of species, their own class and have been for some time.
Excellent vieo! With bearded dragons, it's believed that their third eye is used to show changes in light and dark above due to the flight of predatory birds, their main foes. They can't see properly out of the eye either, but they can register that light/shadow change, and when I've had any of mine outside the passing of a bird will make them flatten and turn to look up right away.

*I think some Dinosaurs were warm blooded, but I tend to think of Dinosaurs as the bird version of mammal-like reptiles (Cynodont, Dimetrodon, Gorgonopsid, ect.). Not quite reptiles or birds, but somewhere in-between with features of both.
@@RRW359 Are Synapsids still considered reptiles? I was under the impression "reptiles" now only refereed to Sauropsida and their descendants.
Excellent video as always Mr. Thomas, and a great subject to boot. I knew a zoologist as a kid who had a tuatara about 60 or so years old he would occasionally use for outreach, it was a real fucking dinosaur! Easily the coolest animal in his care, and he had blue tongued skinks and a new guinea singing wild dog.
Great video! One amphisbaenian genus (bipes) actually retains the front limbs. Also, I would think about them as lizards generally because they are not as highly derived as snakes are.
Ah yes, I probably should have said mostly legless. And lizard is usually used in a paraphyletic sense, excluding snakes and amphisbaenians, but I guess you could probably group them in if you wanted to make lizards monophyletic.
I first learned about the tuatara from a very unlikely source; an encyclopedia from 1916 that I had bought at an antique book store near my home. Ever since then I have been fascinated by this remarkable animal.
0:05 Check out the giraffasaurus.
A third eye may be for detecting objects above the head. Like a certain type of blindness in humans, it allows the brain to detect obstacles around them, but sends no information to parts of the brain that allow the individual to perceive sight.
My green iguana has a large parietal eye. Its about 3mm x 2mm and she hates it when people touch it.
My bearded dragons have them to
Great content fantastic video
Thank you Ben!!
I want one
I'd heard of the Tuatara but until now I had _no idea_ of the Rhynchocephalia! Very fascinating!
Tuatara: the world's most Zen reptile
Yet another unique Reptile that I had never heard of. Very interesting. Great video.................
Its so cute! Who would want to hurt it?
This is a very interesting and educational video. I've read a little about the tuatara and its 3rd eye before, but, never saw a picture of the eye. I also never understood the differences between them and lizards before. Thanks!
And horseshow crabs have nine eyes...
Like the tuatara it has two "eyes" on its back and then six more down the back
That's 8 not 9
this channel is wonderful, keep up the enlightenment
I wonder if any effort is made to kill off the rats at some places so they can expand the reptile's habitat
This has been done on many off short islands, and a new area. Getting rid of all the imported pests is a long term job.
Man i hope it's not too late for these guys to survive. I've never heard of them but just with this one video I love them.
It's third eye is clearly it's substand used to see 10 seconds into the future
such an adorable and interesting reptile!!
"...several theories of what the fu--"
*gasp*
"--nction is..."
*sigh*
I remember seeing tuataras for the first time at the Dallas Zoo. Amazing reptiles! I was so giddy I nearly forgot to take pictures
Not sure why such emphasis is placed on the "third eye" it is present in dozens of species if not more and is not exclusive to reptiles or amphibians, yet your title "The Lonely, 3-Eyed Reptile" implies it's a special characteristic of the Tuatara. Kinda click-baity if ya ask me.
Seldin Gardane Then don’t watch.
@@baneofbanes r/whoosh
You can't tell if it's clickbait till after u watch it
Jacob Hoover this isn’t reddit dumbass.
As a child, 45 years ago, I remember going to see tuatara at the Southland Museum in Invercargill the southernmost city in New Zealand. Only one other city in Chile is further south than Invercargill.
Wasp and hornet species as well as many other insects have third eyes as well. And so do humans. Very interesting stuff
Where is my third eye then
Such a rugged looking beast.
The lifespan is amazing also, got to keep these guys going
And he really understates the lifespan in the video. Henry the tuatara made the news by becoming a first time father at 111. That was over 10 years ago and he's now around 121 years old. Some experts believe tuataras may live as long as 200 years.
Thank you so much for teaching me about the tuatara to pursue my career in hepatology.
These are fabulous creatures. Thanks for the article.
Bearded dragons have that "3rd eye" on the top of the head and it is light/dark sensitive and is useful in detecting and evading aerial predators that would prey on them.
Tuatara are amazing reptiles.
Captive breeding and raising is an effective method of conservation, the Crested Gecko is a great example of that.
I love tuataras, i remember reading about them when i was a kid, such interesting creatures.
They are now #1 on my personal cutest reptile list
unreal. Feels like I’m looking back in time
This is super interesting and informative, thanks for making it :)
Tuataras have beautiful eyes.
Fact filled Interesting and informative film again 👍
With 60,000 to 100,000 Left in the wild. Seems pretty good. Keep going though new Zealand!!!
I had no clue the Tuatara wasn't related to lizards. That's amazing!
Excellent presentation.
This is the second time I’ve watched this video because I enjoyed it so much the 1st time 😊
Haha, glad you like this one so much! :D
I watched a neuro science podcast that discusses this. It is actually an exposed part of the brain. We have one as well but it is located near the center of our brain and is used to produce melatonin and other hormones involved with sleep.
So cool to think that the laat remnant of this Mesozoic group of reptiles survived on one of the most remote landmasses on Earth. It's like finding a mini Skull Island.
4:37 That, is not a dinosaur, it's a modern bird, called a cassowary.
That third eye might be there to help them orient themselves according to the sun. Honey bees have 5 eyes, 2 main large ones for seeing details, and 3 small ones on the very top of their head. These are used to orient themselves to the sun and they use that information to help them navigate to new food sources and to find their way home.
@Bring peter griffin to Super Smash bros They evolved from dinos, yes. However, they are different now. They're not fully dinosaurs any more, close, but not the same. Just as we evolved from apes, but we are not apes any more. We can be considered primates, but we are not apes, just as apes are not monkeys any more.
Birds are now their own sort of species, their own class and have been for some time.
The TH-cam CC changes Rhynchocephalians to "winkers of aliens" and I think that's pretty hilarious. Nice video!
Tuatara are adorable! I sure hope their numbers improve!
its really cool to see an extant species like this!
Excellent vieo! With bearded dragons, it's believed that their third eye is used to show changes in light and dark above due to the flight of predatory birds, their main foes. They can't see properly out of the eye either, but they can register that light/shadow change, and when I've had any of mine outside the passing of a bird will make them flatten and turn to look up right away.
