A few days ago I read about a Veterinarian Chang Po-yu who was reaching through iron bars to remove tranquilizer darts from a huge (400 lbs) crocodile, which was not exactly snoozing, when the crocodile bit down and took the guy’s arm off.
I think this will make anyone who currently treats these dangerous beasts think twice before sticking thier arm anywhere.
From the pics shown, it looked like the croc got the better half below his elbow. Pretty gruesome, you are warned!
