Bull shark

The bull shark is a large, massive, thick-headed greyish shark with a very short, broad, bluntly-rounded snout and small eyes. It has large pectoral fins and a broad triangular first dorsal fin. Bull sharks can be found world-wide in tropical and subtropical seas usually close inshore in shallow water to +200 m in lagoons, bays, river mouths, passages between islands and along surf lines but also many 100 km upstream in rivers and freshwater lakes.
