I took this photo in a crocodile farm in Vietnam. There was extremely little protection from those enormous crocodiles and Alligators, no metal fence, just a small concrete wall 4 or 5 feet high, just enough to prevent the animal from jumping out.
A careless person letting an arm above the wall or a bit too close could die in an instant, since those powerful crocodile could jump in an fraction of a second, and could snap your limb and drag you in the enclosure. A bit scary.
See my other crocodile photos.
