There are 4 types of crocodilian: crocodiles, alligators, caiman and gavialids. Most sources agreed there are 24 species between these four groups but a further 3 species are debated or have been recently verified. In this video, we'll take a quick look at the main differences between alligators and crocodiles before exploring all 27 species.

literally one of the best segway into an ad i’ve ever seen
Misleading thumbnail. Gharials are not only more closely related to crocs but are also more antithetical to gators than crocs are. As a matter of fact it is nearly established that both gharials and crocs evolved from tomistomine ("false" gharials)-like crocodylians and crocs evolved generalist brevirostrine adaptations convergently to gators.
I love the gharial
I never knew that the Chinese have alligator .. hmmm... interesting... 😊

As an animal lover, who sometimes gives educational classes for kids, I understand how difficult to collect all those correct pictures and informations, especially when you want to focus on one species of all kinds. The work is so much harder than most people imagine. These kind of videos are soo valuable. Your team has done really great work !!!
As a animal eater i would love to find more food menu
Now if only our children’s educators would leave the mask cult. (Even the cdc has said it does nothing, aside from medical grade kn95 masks)
I'm an animal lover too and I agree with you. This work really is great and valuable.
@@roellemendoza255 great to here that they serve new menu to us by leaking the animal address very thank for their effort as a animal eater!
There're many databases to use, not very hard to find correct info.
Hi everyone! This was BY FAR the most difficult video so far! As such, just a couple of notes; I found the measurements of each species to be highly inconsistent between sources so where possible I’ve used weights/lengths that are the same or similar between multiple reputable sources. Also, some of the species are visually very similar (yes, caiman, I’m looking at you!) so where possible, I have used only images that are tagged with the correct Latin name and in a location that makes sense with their range as well as cross referencing them with sites like Reptile Database. This was the best I could do without it taking an entire month!
appreciated your effort for collecting all necessary information on this topic, I actually wondering to see such a video explaining these giant reptiles, in somewhat I used to confuse and separate caimans from alligators. I would encourage you to continue your effort and make more such wonderful videos.
Wow! Can’t believe you actually made this.
@Muffinconsumer4 It's funny you say that, because at the end of the video is a direct link to his marsupial video.
Awesome video dude, I hope in the future you'll feature the prehistoric cousins of crocodilians.
What about the Rio Apaporis Caiman?
I remember arguing with my 6th grade class and teachers years ago because they didn’t believe me when I said Florida was the only place where crocodiles and alligators met in the real world. Cool to see that I was right
As a Florida native, I give you a virtual high five ✋
The wide snout difference only really works for American crocs and alligators. Many crocs have very wide snouts.
This video was awesome. I can see how difficult it was to make. Love this video and the channel. You put so much work into these videos, your channel shouldn't be underrated
Thank you! I really appreciate that :)
@@Textbooktravel No problem. Really excited for the next video

Tiny correction for the Nile crocodile bite force: Although it's indeed a Nile crocodile which holds the record for the strongest bite ever measured, it's good to note that among crocodiles the larger the individual the stronger is the bite. Therefore, some of the largest salt water crocodiles ever found would have had a stronger bite, it just hasnt' been measured. Additionally, the 3,700 PSI bite force was measured on a 4.7 m (13 ft) saltie while the 5,000 PSI one was from a Nile crocodile close to the 6 m marks. Furthermore, one was measured in the wild and the other one in a lab setting, so the accuracy might vary.
In science you don't just test one crocodile for these kind of measurements. They test a sizable number of both species. FYI the largest ever living measured crocodile was Gustav in Africa ,Uganda. Also the largest specimens to be excavated are in kenya dating back to millions of yrs ago. Yes salt water crocodiles are on average bigger than Nile crocs, but Nile crocs will have the biggest ever
@@Munyabrwn Gustav isn’t the the largest Croc Lolong was, Gustav is not even a top 5 croc in total size and was never officially measured. Saltwater crocs are hands down bigger
@@kid5042 he was measured. Iknow you will say anything to argue salties to the top. He was measured and experts say they never seen anything like that.
@@Munyabrwn Wrong. He was never actually measured. But is thought to be about 18 feet. Lolong was the largest croc ever measured at 20.3 feet long
@@kid5042 Gustav was measured to be around 25 feet. He was almost 100yrs old and had a complete set of teeth, which is unheard-of.
Never heard before about all those super small crocodilians. They are pretty cool and fun to watch.
'short limbs'
kaprosuchus: heavy silence
You did actually miss one species of crocodilian in this video, that being the Rio Apaporis Caiman. They have a unique yellow coloration, but much is known about them, as they were only discovered to still be alive recently.
The Rio Apaporis caiman is currently considered to be a subspecies of the spectacled caiman, not a separate species in its own right
Not much*
Shout out Forrest Galante
@@tylerjackson5718 Shoutout Sergio Balaguera-Reina, the man who actually rediscovered them.
Forrest galante would be proud
I'd love to have all twenty-seven crocodilian species at my palace. I want to build a moat as well as a small jungle and once we've got that done, ship all the crocodilians and dump them all in. Then my palace would be even more well-guarded. Thanks for your vast wealth of knowledge, comrade, appreciate it!
🤣😅🤣
This took me way too long- I never look at names or PFPs lmao
@@CHloE748 same 💀💀
What you want is Hippo’s my Man.
I would love for one of them to eat you
I really like that you went by geography first and then division of clades. I think it allows the mind to grasp the species distribution much better
Gators have always played a part in my life as a Floridian. Loved learning about the other giant swamp puppy’s.
Till I watched this video, I never knew that Florida or even any part of the USA had crocodilians.
How dangerous is living near Alligators? A river called Nilwala River, flows behind my house in Sri Lanka, and it is full of saltwater crocodiles, so going near the river is very dangerous.
@@Aroo_aroo Well, you need to be aware of them. If they are sunning across a road you can completely damage your car or have a car accident (my mom had that happen about 20 years ago). Houses on the river can lose pets if a dog fetches something in the water. If they are in an office building's retention pond a warning sign will be placed but my state's department of natural resources (South Carolina) will not move them unless certain criteria are met.
@@Aroo_aroo born and lived in Florida for 20yrs. American alligators are super laidback. You can safely assume every body of water from Florida to mid Georgia/Alabama has alligators in it. We still swim and boat in the water anyways since they tend to avoid humans and prefer to hang out in areas that people don’t normally go (tall grass, swamplands, etc) plus are active at night when most people aren’t in or around the water. If you’re not bothering them or their nests they will rarely bother you. I can’t speak for American crocodiles as I’ve never encountered them in real life (I’ve gotten close to several alligators though), but I’ve heard they are more aggressive.
@@Aroo_aroo Gators are typically more laid back than crocs, yet still can be dangerous. I'm 4th generation Floridian and my family and friends have always enjoyed Florida's waters with no issues. But, we also know when and where to swim. I had a neighbor many years ago carelessly wade into a lake at night and he was killed by a gator. They are smart for a reptile and very opportunistic.
@@Aroo_aroo Only in the last few years as American crocodiles moved up and spread has there been some reports of them attacking people. I think his estimate of the amount of American Crocs is surprising as I thought there were less. If you're going to get bit by anything though it will be a very large alligator and that is rare, but they'll eat your pets for sure and small children must be kept away from certain areas as they look like prey due to their small size. One 2 year old was taken by an alligator in Disney World and was never found in 2016. (link below)
"The Florida Fish and Wildlife Conservation Commission has kept records of alligator bites dating all the way back to 1948, and there have been 383 alligator bites on people in unprovoked encounters with the prehistoric-looking reptiles. Of the 383 total incidents in the last 68 years, 23 of those were fatal. Alligators have killed children as young as 2 years old in Florida; several of these deaths are of children aged 2 to 4."

I wish he'd mention how crocodilians digest their food, or at least alligators. They have very little digestive juices so their digestion consists of rotting. Yes the food rots and is why certain parts of an alligators meat will poison you and make a person sick except the tail. It amazes me how some people won't eat wild boar, but will eat alligator tail.
I live at Cuiaba, saw Yacare caiman my whole life, and instantly recognized it by the picture 9:01, unmistakable posing and features
There’s a mother alligator that lives in my pond with her hatchlings, alligators are criminally misunderstood. They’re honestly pretty adorable and goofy looking
Don’t get chomped 😂
Until they eat your dog.
...or your child.
Alligator is cute 🥰
I'm convinced that the burrowing behavior and ability to go for long periods without eating exhibited by crocodilians is one of the reasons that the species survived the End-Cretaceous Mass Extinction. There is a terrific book on crocodilians called "Dragon Songs" by Vladimir Dinets, which is the story of his globe-trotting study of crocodilian mating vocalizations and mating display behavior. It is quite a yarn!
crocodilians are the closest living relatives to birds, which together are called archosaurs. This group also includes the now extinct Pterosaurs, non-avian dinosaurs and pseudosuchians.
Just a thought-- Nile Crocs are wayyy more aggressive than salties, so when they test bite force with a bite stick, a Nile might be biting as hard as it can out of aggression, whereas a salty is simply giving a casual, half-assed chomp.
hell nah salties way worse
I was born in Cuba and I can confirm that Cuban crocodile can be found in many other lakes and rivers in Cuba or there is another specie that is not mentioned in the video but I'm pretty sure I have seen them in other places.
American crocodiles have a wide range in cuba, so they are probably what you saw
@@harislittle9241or crossbreed crocodiles
Though they look scary, i actually have an unexplainable fascination of the crocodilians! Really hope to one day see both crocs and gators in the everglades
It's their teeth 😁
Beautifull and delicious..., just like me
🤦♂️(jk of course)
But crocs/alligators etc. are👍
Just like this video and your comment.... And that is true 😁.
Greetings bibia.
They look prehistoric, and maybe brings up some long forgotten subconscious fear and awe that we have about them. For thousands of years, our ancestors had to worry about these things murdering them while getting water everyday. Its crazy to think about
Please no crocodiles in the Everglades.
I was not expecting that Chinise alligator to be that cute
It looks like a baby dragon
I am autistic and my special interest is crocodilians and has been for over a decade. This is such a fun video thank you so much for making it!!!
An alligator will see you later
A crocodile will see you a while
But the caiman was always late
But he still caiman!

What about gharial🤣?

@@Textbooktravel thanks for your kind reply

I'm probably the only one, but is anyone else here after watching CHimerasuchus's many videos of prehistoric crocodylomorphs and realizing the biology and evolutionary history of the crocodilians is a banger?
Also, 1:17 may be the slickest sponsor transition I've ever heard 😂
His channel is awesome!
Being an Aussie, I can tell you, yes we use these names for our crocodiles, but mostly we call them 'crocs'. We really only use 'fresh' or 'salty' to differentiate between the two. So it is 'Freshwater Croc' and Saltwater Croc'
to put the evolutionairy relation between crocodiles and alligators in perspective. we are actually closer related to rats than alligators are to crocodiles. and caiman actually share a closer anchestor to alligators. being the second sub-family of alligatoridae (caimaninae).
Lol ok

as a biology undergrad planning to pursue a masters in ecology, your channel is underrated, the videos have the lenght the need + you explain this on point.
I hope you grow fast:)
With a focus on herps?
@@PonyFoot123 nope i dont plan to specify on a specific group. Atm im doing my bachelors about the interaction of microbes and fossilization..
But yeah im also a paleonerd since young age, so you could surely say i focus on herps. As im most interested in paleontology , to specify dinosaurs and other prehistoric reptiles;)
If you would ask which group i would specialize later on.. easily reptiles or birds. Tbh mammals i never found that interesting. In contrary, inverts espc insects and molluscs are also worth pursuing
I was fishing under the bridge in the keys and 2 big Crocodiles swam by 2 meter away from my feets while I was fishing, it was a cool experience, I remeber looking at them while they were swimming by, they were beautiful
As a crocodilian lover, I want to thank you for this video, I love seeing people interested in crocodilians, they're such beautiful and powerful animals ❤️
what a great way to end my day with a 23 minute long video about crocodiles,alligators, and caimen
Dude I’m so happy and excited to see this video; I mentioned looking forward to if you would ever do crocodilians before and this feels like a dream come true! It also happens to be my birthday so this feels like an extra special treat to get to watch :) Appreciate all the amazing work you do on these vids!
Happy bday ‼️
Great video, insanely well presented and well informed, though I think you should have added a little tidbit on Gharial... The Males have this large bulbous organ on the tip of their snouts called a Ghara, due to it resemble the shape of an upside down round earthen pot used commonly in India which is also called the Ghara... This where the Gharial got it's name from
This video was incredible. I can imagine how challenging it was to create. This video and channel are fantastic. Your channel should not be undervalued because you put so much effort into these videos.
YOU ROCK! keep it up! Exceptional work, and I love the amount of detail in your work. Most other craters are much more vague about what creatures they represent.
My personal favorite is the Cuban crocodile (I think you can take a guess why lol) and yeah, it's a shame they're critically endangered. On top of their very limited range, their habitat overlaps with the American crocodile. And because of this, there has been instances of crossbreeding. Not to mention they've been hunted a lot by humans. While yes, they are the most aggressive of the New World crocodiles, they can't keep up.
That Chiquita video was my first introduction to this insane creature.
Chandler knows that first hand
Yes absolutely superb crocs, very dragon / prehistoric looking . I really hope some attempt at protecting these animals is Underway
I’ve held a Chinese alligator before. Really cool animals and they are incredibly rare in captivity (I believe there’s something like 20 or less in the world as pets). The owner was preparing to travel to China to breed it with another captive one
A Number of Zoos have Chinese Alligators.
Correction, the saltwater crocodile is the largest crocodile and the largest reptile and it has the strongest bite force.
Great video! Only one slight problem: there is no debate, the Quokka is by far the cheeriest animal to ever exist
i came across some articles on the subject listing two types of philippine crocs. one is the more common salt water type same as those in australia,indonesia and new guinea and a rarer almost extinct fresh water specie, much smaller, found only in the sland of mindoro.
With how many species of animals are on this planet, I hope this series still has long to go 🙏
Man, this was a really good job you did. And yes, what you say is true: there are a lot of different sources out there which give sometimes very inconsistent (and inaccurate I would add) information. I'm not an expert but I know quite a bit about crocodilians, and this video helped me a lot. Thank you!
Looking forward to hearing about the gharial.
🐊🐊🐊
They are so fascinating! I wish I had more time to talk about each individual species
I still love the ‘animal tapas’ you present in your videos! It’s so important to show a sampling of animals so people can find the ones (that they might not have known about) that inspire them. I believe this leads to conservation.
I was so happy when you talked about the Jaguarundi in your cat video. That’s an animal that truly inspires me. Have a great day!
Love your videos as always, very informative. Just one thing- I believe you may have left out the rediscovered Rio Apaporis caiman? Unless, of course, I may have missed some info.
I love your channel so much! I found your snake video and fell in love. I love the content man keep it up and take your time where needed ❤️
Great vid, but one Croc that has been forgotten (probably because it was fairly recent) was the Rio Apoporis Caiman. It was originally considered extinct but was rediscovered and recorded in a documentary by a guy called Forest Galante.
Babe, wake up! New gators just dropped!
Good content. Thanks for covering this tipic.
I was looking for this before l video back in December! Thank you so much for making it 🙌
Isn’t it strange how the shoe company is called crocs but they look like alligators 😂
Tomistoma is actually quite large, potentially reaching 6m in length. The longest crocodilian skulls also belong to tomistomas.
Awesome video! Would love to see one on the subspecies as well. Really informative!!
Fun fact: Gharials are most aquatic crocodilians, and are not able to high walk. When they are basking on sandy shores, they slide down on belly when they sense danger.
And its least dangerous
Great video and super in depth breakdowns of each's habitats.
This is one of the most entertaining and informative videos I’ve watched in a long time. Thank you.
Absolutely interesting and informative. Thank you for this video!
Interesting! My favorites are the, Saltwater, Nile, Crocodiles, and the Speckled Caimen 🐊🥰
Bite force quotient(pound for pound) for crocodilians is more or less identical over most species. The Nile crocodile that registered 5000 psi was field tested, and undoubtedly larger than the Saltie that registered 3500 in a laboratory setting.
Very well done and a great reference video 👍
Cuvier’s Dwarf Caiman looks like a tiny proto-Dino, love to see the reptile faction continue to branch out into new playstyles
The broad snouted caiman is really common where I live. So common that you can easily find them in lakes in parks around the city. It's local name is "jacaré de papo amarelo".
As a Floridian, I can assure you that alligators frequently visit brackish and the Gulf of Mexico on a regular basis.
And they get larger than 15'

I love your videos! Thank you so much for making these and putting so much work into them!!
15:25 is actually and Indian Gharial, not a Slender-Snouted croc (18:02 same thing) (thumbnail is also VERY wrong)
Also: the Gharial and Tomistoma are not considered crocodiles, but their own (third) group of Gavialidea
(Also also: pronounced GAHrial, not GharEEhal)
This was just the video i was looking for to learn about all these species!
Great video! Also forgot to include the Congo dwarf crocodile osteolaemus osborni, theirs a documentary on it and also another unnamed dwarf crocodile for the upper guinean rain forest of West africa osteolaemus frontatus, I believe they were discovered back in 2008 but was not widely covered and has yet to have a full description. The species list will certainty go past 30 I suspect finding more cryptic species in the future. Also interestingly the Borneo crocodile does not have any photos or drawing of the species, would certainly need conservation status assessed.
Thank you, excellent video, was very educating
Amazing video, good work mate!!
0:09 look how happy this one is!
I don't know how i got here, but the narration and the video was so interesting and entertaining that I stayed till the end and was amazed how many and really beautiful crocs&gators are out there.
The most important fact , you see an alligator later , and a crocodile in a little while, disappointed this hasn’t been mentioned .
What a great video, had me engaged from start to finish.
A truly impressive video of some very impressive animals! My sincere thanks for honouring them in this way.
Thanks for the indepth presentation.
Great video man, keep up the good work!
hi! great video, and i'm sorry if this was already listed in the description sources links but do you have a source for the african slender-snouted crocodile being sorted into the two subspecies by the cameroon volcanic line? it's super interesting how even offshore volcanoes could possibly influence the evolution of subspecies and i'd love to learn more. 🥰
Here’s a study and a couple news stories of the subject:
“Systematic revision of the living African Slender-snouted Crocodiles”
“Entirely New Species of Crocodile Has Been Discovered-And It's Got Soft Skin”
“Back from the Brink: International partnership helps conserve critically endangered crocodile, gets zoo back on its feet in post-war Ivory Coast”
Anything from Matthew Shirley I’d recommend reading, as he’s been one of the main people involved in recent crocodilian taxonomy in Africa.
I’d never heard of the vast majority of these species. And that’s why I love these videos!
Fascinating video! Thanks for this fun information about crocodilians! Loved learning abt them!
This was a very good video, very informative and educational. Well done! Thanks for sharing
I find the Orinoco Crocodile to be my favorite, as the reported sizes of over 23 feet make them the longest recorded crocs, but these accounts were a long time ago and it is believed they can no longer reach these sizes due to increased environmental pressure.
I see people keep bringing up the fact the video left out the Rio Apaporis Caiman, it's not a confirmed species as of now. It most likely won't receive full species status, as genetically its similar to another sub species, Caiman crocodilus crocodilus. In fact, the exact number of crocodilian species is up for debate. As of now the IUCN Crocodile Specialist Group recognizes 24 species of crocodilians, the newest species being the West African Crocodile. They do recognize the possibility of more species such as two species of Slender-Snouted Crocodile, and 3 species of Dwarf Crocodile. They don't even mention Hall's New Guinea Crocodile, but this will most likely change. Crocodilian taxonomy has been a hot topic for the last decade, so I wouldn't be surprised if we get up to 30+ species within the next few years. This video did indeed go over every official species of crocodilian, and I'm surprised it discussed the Borneo Crocodile too, as it doesn't get a lot of attention.
American alligators have also been documented exhibiting cooperative fishing behavior. There are films available where American alligators are shown gathering in groups to feed on migrating garfish. These alligators seem to know when the migrations occur as they gather before the fish move.
Some great images. Very informative 👏 👌
I'm here for the baby alligator and crocodile pics
Very nice and informative video. Only issue I found was questionable rounding of metric values for length. 12 feet (3.66m) and definitely 13 feet (3.96m) should be given as 4m if you want to avoid decimals.
That ad... I almost never like ads, but the one here was worth watching ("...and other data you'd like to keep private").
And obviously, great content. Thank you!
This channel is awesome, everyone at any stage of life can learn from these videos!

YES I HAVE BEEN WAITING SO LONG FOR ANOTHER VIDEO: (side question: How long does it take to make a video?) 🐊🐊🐊🐊🐊🐊🐊
Haha! Sorry! I'm working on getting them out faster but I don't want to compromise on quality! Generally, for every 1 minute of video it takes between 3-5 hours of work including research, writing, voiceover and editing but it depends on how many graphics there are, how easy/difficult it is to research, and also the type of media I can find
