Isn't he beautiful? He was getting a bit irritable by this time but couldn't bite anyone with the wrangler person's hand round his head.
He's a baby freshwater crocodile, a freshie. Proper name Crocodylus johnstoni.
Freshies live in northern Australia (Woy Woy is in south-eastern Australia), lay eggs and live at least as long as humans, grow to the length of a basketball player and weigh as much as a sulky teenager. They eat insects, fish, frogs, lizards, turtles, bats, birds and incautious tourists.

Didn't hear over if this fella was a turtle or a tortoise. You can see most of his neck there I think. It was long and snakelike.

The only way is up, baby! He was beautiful. He felt soft and warm and smooth. (Make your own dick jokes.)

Snake buying advice
Did you know herpes is named after snakes? Neither did I but it's right there in the Oxford. The Greek for reptiles is herpeton and snake-fanciers are called herpetologists.
