Here is some more information:The bull shark has a short snout that is wider than it is long (hence its name). Its belly is off-white, its top surface is grey, and the eyes are small. The first dorsal fin is much longer and more pointed than the second dorsal fin. A pup’s fins have black tips, but these markings fade in the adults. The females are larger than the males as is often the case with sharks. The bull shark is also know as the cub, Ganges, Nicaragua, river, Swan River Whaler, Zambezi, shovelnose, slipway grey, square-nose, and Van Rooyen’s shark.

Below is a picture of a Bull Shark considering eating a man.  After tasting him, I think he decided he was a bit tough.  Younger humans are more tender.
