Reptiles are a diverse and successful group. With over 8,000 species found worldwide, only around 100 species can be considered marine reptiles, including sea turtles, marine iguanas, sea snakes and crocodiles. They retain the defining characteristics of reptiles, including tough scaly skin that covers their bodies. But in addition, marine reptiles have developed a number of specialised anatomical and physiological adaptations to survive in the oceans. We'll take a closer look at these in this film.

Amazing
It's not bat-esian mimicry, bait-zian like "bait's Ian to punch him as the principle walks past." I'm sure there's a scientist to back that up and with a quick google search I have the answer 10 seconds later. "It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil."
Do you purposely mess up 2-5 word pronunciations per episode to drive up engagement or do you really not know? If you don't know then it would strike me as an odd job choice for you.
@evilcanofdrpepper Pronunciation is the least important consideration in anything! It varies from place to place and person to person. As long as spelling, usage and definition are accurate, pronunciation hardly matters. While researching for this video I found sources for both ways of pronouncing Batesian, and of course know of the work of Henry Walter Bates as I’ve researched his findings extensively. Put aside your hang-ups about which pronunciation is accurate and try not to nit-pick.

Aehm, I think this one is narrated by an alt lvl voice ♀️
Some of the most interesting marine reptiles to me are the extinct Palaeophids. This was a group of sea snakes more related to Phytons (living sea snakes are venomous and more related to cobras). Some of them could've reached sizes of 10 to 12 m. Today one of the most famous Cryptids are the so called "Sea serpents", but back in the Early Cenozoic, they were real 🤯
Phytons?
@@banhatlessducks probably meant pythons
Never heard about this one so I looked it up! Here’s the wiki link: en.wikipedia.org/wiki/Palaeophis. Very interesting species and especially since fossils have been found in my home country (it’s quite rare to find anything from back then as we are a pretty flat country and thus we were entirely submerged).
They were also far more active than sea snakes.
I want one. Phytons are snakes composed only of light.
@9:51 "Gently pick up her young."
Uh...I imagine this is relative to how a crocodile would normally bite a fish? Because that looks about as gentle as the critical reaction to the last Coldplay album.
Ever since Subnautica and Abzû came out, I’ve been fascinated with the ocean and it’s creatures. Not only are your videos engaging and educational, but your voice is so calming that once I’m done learning, I’m also putting on playlists of them to relax and fall asleep. It’s wonderful.
Thank you so much Mike!! Those are my two favourite games, they perfectly capture the wonder and mystery of the oceans. I’m so glad you enjoy my videos, it’s so wonderful to know they can be used for both education and relaxation.
The opposite for me, Subnautica gave me thalassophobia lmao.
This man is the next David Attenborough. A calming and welcoming voice, while so knowledgeable about the subjects at hand. Honestly it’s quite wonderful to see. Keep up the great work!
Edit: Y’all I commented this 5 months ago at current time. I don’t care if you like or don’t like Leo or David. I like Leo. I think he’s great for what he is and trying to do. If you don’t have something nice to say don’t say it. Think about the people on the other side of the comment. And stop replying to something so old. It’s weird.
Aw thank you so much ☺️💛
absolutely
I was just wondering if he’d heard from Attenborough yet. I’m sure he’d be interested if this channel came to his attention. He really is a very gifted writer and narrator. He really draws you into the subject.
@jztouch I wrote to him twice when I was very young (about 8 or 9 years old) and told him about my channel, which was very different at the time as I was so young. Both times, he wrote back! With a signed photo! He truly is an incredible man :)
I hope he becomes the next documentary voice of my era. So soothing!
Since during the Cretaceous giant marine turtles such as the famous 4 m long Archelon were widespread around the world, imagine if they too migrated in large numbers and went all at the same time on a beach to lay their eggs, it would've been an increible sight.
I think they find fossil of sea turtle that was squashed by sauropod.
@@ExtremeMadnessX I don't remember if it was a sea turtle but yes, that poor guy got obliterated by a sauropod foot
ever ceases to amaze us with the wonders of the water world
I love how the crocs slide on the mud. Looks like fun
Weeeeee
Did not know some sea snakes can absorb O² through their bodies underwater absolutely fascinating.
As for salt water crocodiles they may look slow and cumbersome on land but I can attest they can sprint very fast for short periods of time, I live surrounded by crocodiles in NT, Australia only ever seen the one run but it definitely taught me not to be complacent. Usually though crocodiles are very lazy especially during the day they do their hunting in the mornings and afternoons, if you are ever camping near crocodile waters make sure never to go to the water at the same times, or in the same area, move further down the banks. It seems crazy but crocodiles watch and wait for creatures that go to the same place around the same time as they are ambush hunters.
In comparison to my friend who worked with crocodiles capturing, rehabilitating and even working as a handler at the parks, my knowledge is very limited, but I can definitely say they are smarter than most think, they are always watching and always learning.
Leo, another amazing video, it's absolutely refreshing after years of watching high budget documentaries that teach me absolutely nothing except that X location is beautiful in HD and here's some pretty animal pictures to finally watch documentaries where I am learning something new again. I don't know how but we need to get you some of that NETFLIX money 😂 I would be happy if you changed nothing and just kept the money for yourself because this alone is worthy of top tier.
Stay safe, happy, and healthy
Thanks for the insightful comment! I’ve never had the privilege to encounter a wild crocodile for myself, but they sound incredibly imposing. Definitely one of nature’s most impressive animals.
Thanks for the kind words, I’m so glad you’re enjoying my videos as they’re a joy to create! Comments like this make it all so worthwhile :)
It seems that American alligators also share a similar level of intelligence. Snake Discovery rescued one, Rex, several years ago who was kept as a pet from babyhood. She is now 35ish, stunted at 5ft long and has retained her baby colouration.
Rex is trained to specific words, people and target trained for food. At first they had to keep her in their home - rescued from a 4 ft box (she was 4ft at the time) to having a decent sized bedroom with as big a pool as they could get in there. She grew over a fit despite her age!
They've opened up a zoo/education facility and Rex finally has a good sized pool to stretch out in. She watches the visitors and learns patterns, and refuses to play with toys on camera! Much like some cats, they don't want to be seen hunting even if it's the humans who feed them
Tho she does follow Emily as she moves around the zoo and comes over to be closer. Probably in hopes of food but it's still cute to human eyes
My grandpa said that one time he was snorkleing in the mariana trench he was attacked by sea serpents
I don't know about salties, but in Florida we have plenty of crocs and gators. Yes, they are surprisingly fast when they need to be. Terrifyingly so.
Where lay their eggs the sea snakes, that piece of info got missing :)
Absolutely one of the best cannels on YT for nature documentaries. Excellent editing and the voice is amazing!
Thank you so much! Thats really sweet of you :)
I saw this and I grabbed one of my snakes and was like "yep you're watching this with me" I love all reptiles
Not all other reptiles abandon their eggs, some pythons actively brood on/around their eggs to stabilise temperature and protect them from predators. Burmese pythons and beauty snakes wrap around their eggs
I like how you repeat and reinforce terms and concepts across numerous videos.
I’m really glad you find that useful! I always try to link between topics/videos wherever possible just to highlight how interconnected the ocean’s many systems and habitats are :)
@@NaturalWorldFacts As others here have said, you have a voice and way of speaking that seems tailor made for narration (obviously intentional). I hope youtube is a springboard to a rewarding career, sir.
absolutely CRAZY the amount of work that goes into these amazing videos, from editing to research to narration. and we get to watch them for free!! maybe the modern world has its good points…….
They’re a joy to create, so it’s really no trouble at all! I’m so glad you’re enjoying them 😊
Stress Reliever
Last time I was this early, Banjo and Kazooie were just announced as DLC
I'm always happy to get the notification of a new upload. I look forward to these videos. They're very educational while also being very calming.
just finished watching a loggerhead turtle lay eggs, perfect timing!!
The narration is so relaxing not to mention the background music... its perfection...
Aw thank you so much!!
Your account is godsend.💚I love marine reptiles, so this is definitely my personal favorite video of yours so far! Of course, all your uploads are spellbinding.🌊✨
Aw thank you!! I’m so so glad you liked this one ☺️
I rarely feel the need to comment but I have to praise you for your amazing output, from the background music to the captivating information/voice over/unique topics. Thanks mate.
Thank you so much Dylan!! Comments like this really make it all feel worthwhile :)
I'm sure you get this comment often, but I really want to thank you for these videos, and the incredible work you put into them! It really shows in every video I've watched. My biggest hobby is writing, and oftentimes I like to add in certain details from the real world such as animals, so your videos too are not only soothing, but very informative and helpful with my process! I also really appreciate that you credit the background music! It's rarely something I see any channel do and it's a small thing but I really appreciate it.
I can't wait to see more of your work, happy holidays to you and yours :)
This guy has such a calming voice and articulates himself beautifully.
Please don't ever change, keep making your videos like this! You find the most beautiful footage and your voice is just peace to the ears! A big giant thank you for popping up in my suggested videos, im a subscriber indefinitely!
The way saltwater crocs slide across the mud is so cool! And the babies are unexpectedly so cute
in 12 minutes of video you gave me two pieces of information I was completely unaware of...BRILLIANT. Excellent mini documentary, I tip my hat to all those who worked on it. NatGeo eat your heart out.
Thanks Rocco, I’m thrilled!! These are a joy to create so it’s wonderful that you learned something new :)
I adore your content! Batesian Mimicry is named after naturalist Henry Walter Bates, so it’s pronounced ‘bates-ian’ though. c:
Thanks for the correction!! I’m actually working on a video all about mimicry itself at the moment and spent ages trawling through pronunciation videos for ‘Batesian’, with each one giving a different answer 😭
Your version makes the most sense I think, so I’ll definitely by using that when it comes to recording :)
@@NaturalWorldFacts biology graduate here! Can verify, it’s named after Henry Walter Bates and pronounced awkwardly as a result. I’ve made that mistake in a presentation before!
Glad to hear I’m not the only one haha!! Cheers for confirming that, I won’t be making this mistake again 😁😁
This is pure magic, thank you for making such inspiring content.
It’s my pleasure!! I’m so glad you enjoy them
Honestly, this channel is definitely starting to be up there among my favourite nature documentary channels. My problem now is that I can't find the time to watch all the videos of all my favourite channels. Fortunately though, a lot of your videos seem to align closely with the topics covered in my courses, which makes me feel like I'm procrastinating less and learning more with these videos. XD
Thank you so much!! That’s awesome, what courses are you studying? :D
The fact that sea turtles remember where they were born is fascinating.
Those crocs sliding down the mud looked fun af
Leo your such an amazing young man! I couldn't believe it when I saw how young you started doing this. Without doubt your the next generations Sir David Attenborough !!! Thank you !!
Thank you so much Lorrie!! You’ve made my day, I adore making these videos but comments like yours make it even more rewarding :) thank you!!
Boom! Great video as always!
I Love loved this.
Your voice is so calming too. Thankyou x
Literally my favorite TH-cam channel. Will be going to college next year for marine biology and I’ve watched all your videos and they’re all amazing
i absolutely love this video, your whole channel is a well of comfort
Good stuff although I will note that not all other reptiles actually abandon their nests, there are several species of snakes and lizards which demonstrate some level of protection such as the viviparous monkey tailed skink.
You da man! Excellent as always
These videos are masterpieces. One of the best narrators I’ve heard. It’s so wonderful to hear a beautifully-written & perfectly narrated video for once. Thank you!
This made my whole month 😭 it’s been so stressful.
Holly Kal, we're all living in a very stressful time these last few years hey 😪 I hope you watch many of Leo's uploads and find them as calming as I do 🤗 he's definitely doing an amazing job with his channel, and there's a lot more videos to watch on other subjects on nature, peace out lass 🤗 I hope you have a better month in December and into the new year 🤗
As always, you have given us absolutely fascinating information with details that we could not have imagined without your impressive store of data. Thanks again Leo!
Amazing stuff as always! Many thanks!
Thanks again Leon!
Thank you for the wonderful video and the one week trial with Endel, looking forward to giving it a try
Thanks Erica!! I really hope you enjoy :)
The narrative so soothing and the vids have consistent quality. Thanks! It is a very meditative and informative video!
Great content, thank you for sharing!
Excellent video
Thank you so much for the excellent episodes!
Thank you so much for watching 💛
This man's voice makes me feel very comfortable
Outstanding content man. Much love from Brasil!
amazing in many ways. a spetacular selection of images and a well done speech
So cool that educational documentary quality videos like this are here for free on TH-cam. These are nice videos to watch before bed
Another great video! Thanks man
Cheers Paul!
I’m not the type to comment things like this normally, but hey it can’t hurt.
I’ve recently gone through a tough breakup after moving to sunny South America with my boyfriend, meaning I’m losing a lot of my new life and about to be moving back to our miserable, gloomy little island of a home country, a prospect which terrifies me and in recent times left me feeling down enough that the unthinkable became a possibility.
But then, I found you and your channel, and for the first time in so long I’ve felt that warm comfortable feeling in my chest again, every video is a trip to somewhere more peaceful and quiet where I don’t have to think contemplate, fight or question anything. Just peace.
So genuinely from the bottom of my heart (and as a fellow Brit),
thank you for all that you’ve done here, you’ve helped someone begin to get out of a very dark place.
I love these videos. The voice is so calming. I've saved every one of these videos to it's own play list.
Aw thanks so much Angela!! I have a complete deep sea playlist here too if you need to find everything on one place: th-cam.com/play/PLKzq2xKdfIot0rJTxkzPG7srMQm0sSeIG.html
A very informative documentary👌
Fascinating and educational. Thanks for this!
Great video 👍😊
I really like the very soft spoken narration
I’m in your discord server and I’m shocked no one seems to talk about the beauty and amazing.. everything!.. of your videos. It should be talked about more!😌
Aw thank you so much Aaron!
Great work! I didn't know anything about sea snakes, so that specific section was quite fascinating!!
Really fascinating how powerful a saltwater Croc's bite force is, but also gentle enough to carry their newborns.
Another wonderful video! This is one I really knew nothing about! Thank you.....OXOXO
Narrator: Crocodile gentle pick up her youngs with its mouth
Mama Croc: Nom! Nom! Nom!
Loving your content!!! Thank you for your beautiful work ❤️🖖
Thank you so much 💛
Fantastic video.
I’d love to see a turtles/tortoises video from you. Maybe you could touch on how they evolved away from eachother. Keep up the great work.
Amazing mate 🐸💚🐸
I love how amazing this video was,and it's pretty good.
Wow this is perfect to watch before bed, thanks!
great video
Thanks for another amazing video.
Thanks Anna ☺️☺️

Thank you so much Stacy!! Your support really means a lot ☺️
The voice is so smooth.keep up the great work👍
Thanks so much!
Thanks for this one, Leo. I’m pretty sure you have a great future ahead of you. 🐨🇦🇺
These are dope af.
Caught ur vids early lets go
Your voice reminds me of the narrator from the live action movie of A Series of Unfortunate Events. Very soothing, very clear, and a gentle cadence
I love these videos. I sleep so peacefully if I fall asleep to this
This is a really good yt channel :D
Aww cheers ☺️
Evolution never ceases to amaze
please, never show me a turtle eating again... other than that, great quality work as usual. I watch and rewatch your videos often!
Beautiful...
Favorite video
Another great video Leo, I've shared this video and recommended your channel to my friends, keep up your amazing work pal 🤗 💞 🤗
Aw thank you so much!! I really appreciate that
@@NaturalWorldFacts no worries pal, I'm having a difficult day, but your videos are a great respite from the daily grind of work and the struggle of this bloody pandemic, especially working outside in London, gonna have a sleep, been up since 2am and was in work at 6am so I guess I'm just a little run down, the winter blues hey 🙄 need some sunshine ☀ 😁
Amazing
Like the sea turtle, I also must cry when I return home to survive my living conditions
If you want to practice your listening skills this channel is recommended for you. Style, diction, tone and voice is amazing.
Alr this is officially one of my all time favorite yt channels
Thank you so much 😁😁
You are literally my comfort channel
Aw that’s so lovely!!! I’m really really glad my channel’s able to be that for you ☺️
I have a ton of comfort channels that I watch too, so it’s really nice to know my own videos are used in that way :)
@@NaturalWorldFacts Of course! Your videos honestly helps me unwind after a long day :D
bravo pour cette vidéo .les images sont superbes. les commentaires ont très instructifs
Marine reptiles may be less in diversity compared to the past, but still there are many. Sea turtles are quite well adapted and don’t really have a need to change radically from the ancient forms. Sea snakes are still in the early stage of their evolution and who knows what will happen after tens of millions of years.
A few non-crocodilian reptiles do also show parental care.
Maybe in a couple millions years those sea snakes or marine iguanas will evolve to become some kind of mosasaur like giant sea reptile
You just can’t watch any of these videos without learning. Thank you
The narrator’s voice is so soothing and pleasant
Thank you ☺️☺️
Turtle: can navigate their way back to birthplace from thousands of miles
Me: gets lost in small forest near birth village and emerges several miles from where I intended XD
I loved it
Beautiful ❤❤❤❤
Nice nature vedio
