| GENERAL
DESCRIPTION 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 gray, 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 marking fade in the adults.
The females are larger than the males. 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.
TEETH Bull shark teeth are triangular, serrated (saw-edged), and very sharp. The teeth are located in rows which rotate into use as needed. The first two rows are used in obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth that rotate into place. |
