Christine, part of their natural habitat is my place. Last wet season a roughly 3 metre (about 9.8 feet) Estuarine Crocodile came through my place. How many times it's been there when I haven't noticed is anybody's guess. I liken it to being in a city where you can walk around and not worry about cars provided you do the right thing. Do the wrong thing and you can be killed by them. It's the same with crocodiles.
Whilst first starting as a Crocodile Cubit, questions/comments about other reptiles made me decide to broaden it to other reptiles as well, and frogs. There's very many groups and species but I'll cover what I come in contact with and photograph.
