A man has apparently been taken by a saltwater crocodile on Australia’s Endeavor River. Read the story here.
Saltwater crocodiles are among the premier predators of people. They take no special interest in us; rather, they're generalists who will take any prey of suitable size. A croc over ten feet long is considered large enough to prey on people. In the case of salties, it's generally the males who hurt people because they more often reach large sizes. (The largest ones go about 23 feet. At that length, they weigh more than a ton.)
