Crocodilians: Natural History and Conservation is the Internet's largest crocodile site, established in 1995. Written by a crocodile specialist, it's an ever-growing database of everything you need to know about crocodiles, including all the different species, their biology, conservation, how they talk, and even their captive care.

When you can't trust Wikipedia, come straight to the source.

Articles and Essays
Five major new sections are in the works...


1 July 2011 - A new look
Welcome to the newly designed front page for - something that's been long overdue. The entire website is getting a serious shakedown right now, and I'm being assisted in this enormous task by Brandon Sideleau who's a wildlife photographer and crocodile afficionado based in California. The sections you see above will be joined soon by several exciting new ones. One of these is basically content-ready, but the page design needs to be implemented, and we have plenty of material for the others that just needs tidying up. We're still tweaking the design of the front page, so this may not be the final look, but I hope you like it.
