Bull Shark

The bull shark (Carcharhinus leucas) is also known as a River Shark, Estuary Whaler, Freshwater Whaler, Swan River Whaler, Ground shark, Slipway Grey, Zambezi and Shovelnose. It belongs to Family Carcharhinidae under Order Carcharhiniformes of Class Elasmobranchii. It is commonly found worldwide in warm shallow waters along coasts and in rivers. Bull sharks are often found near estuaries and freshwater inflows to the sea.

The bull shark's body is large and stout with a short snout. The eyes are comparatively small and the body is without inter dorsal ridge. The color of the body is predominantly grey with a pale to white underside. The Bull Shark has two dorsal fins, of which, the first dorsal fin is 3.2 times longer and more pointed than the second dorsal fin. Pectoral fin is rather large and broad. It can reaches up to 2.4 meters in length and 130 kg in weight. Its food consists mainly of bony fish, sharks including other bull sharks, turtles, birds, dolphins, terrestrial mammals, crustaceans, echinoderms and stingrays. It mates during late summer and early autumn. After gestating for 12 months, a bull shark gives birth to four to ten live young. During the juvenile stage, the dorsal fin is black at the edges and becomes lighter with age. The young are about 70 cm in length at birth and reach sexual maturity at the age of 10 years. Coastal lagoons, river mouths, and other low-salinity estuaries are common nursery habitats of bull shark. It is preyed upon by larger sharks, such as the tiger shark and great white shark. Females can live up to 16 years and male to 12 years.
