Never smile at a crocodile.....don't be taken in by his welcome grin, he's imagining how well you fit within his skin......
It's a children's song. This photo is a freshwater crocodile taken at Windjana Gorge in Western Australia's Kimberley region - one of the prime viewing areas for freshwater crocodiles. They are reputed to not be dangerous, but don't step on one or get in its way! The song came immediately to me - this croc looks like he is smiling at me!
