“Now this size crocodile, he wouldn't kill you by biting, unless he bit you in a certain place. But he would drown you quite easily,” explains Tom Nichols, a wildlife ranger in Darwin, Australia. Nichols says crocodiles kill by doing a death roll: biting their prey, dragging it underwater, and spinning violently. That’s how Nichols lost half his left hand. Saltwater crocodiles are the largest reptiles on the planet – much bigger than alligators. According to some scientists, the Australian saltwater crocodiles, known as salties, are the world’s most aggressive. Salties’ numbers are surging in Australia. #crocodiles #salties #darwin #australia
