This is a big, stocky and powerful shark, with our biggest females reaching more than 3 meters in length. The males are smaller at approx 2 meters and can be recognized by their white copulating organs, called claspers.
Bull sharks can be identified by their large size, massive build, grey color with a pale band reaching into the tail, small eyes, a nearly triangular and slightly falcate first dorsal fin and a very short snout. They are thought to be generalist feeders with a special propensity for preying on other sharks and rays.
Like most sharks in their Family, Bull sharks are placental viviparous, i.e. they give birth to live, fully developed pups after a pregnancy of approx. 10 months, this on average every two years.
