Bull Shark

Bull Shark

The Bull Shark, Carcharhinus leucas, also known as the Zambezi shark, is a shark known for its aggressive nature. They have even been known to travel as far up as Kentucky in the Ohio River, although there have been few recorded attacks. They are probably responsible for the majority of near-shore shark attacks, including many attacks attributed to other species.


Bull sharks are large and stout, with females being larger than males. The bull shark can be up to 81 cm (2.66 ft) in length at birth. Adult female bull sharks average 2.4 m (7.9 ft) long and typically weigh 130 kg (290 lb), whereas the slightly smaller adult male averages 2.25 m (7.4 ft) and 95 kg (210 lb). While a maximum size of 3.5 m (11 ft) is commonly reported, there is a questionable record of a female specimen of exactly 4 m (13 ft). The maximum recorded weight of a bull shark was 315 kg (690 lb) but may be larger. Bull sharks are wider and heavier than other requiem sharks of comparable length, and are grey on top and white below. The second dorsal fin is smaller than the first. The bull shark's caudal fin is longer and lower than that of the larger sharks, it also has a small snout, and it lacks an interdorsal ridge.

Bull sharks have a bite force of up to 600 kilograms (1,300 lb), the highest among all investigated cartilaginous fishes.


The bull shark is commonly found worldwide in coastal areas of warm oceans, in rivers and lakes, and occasionally salt and freshwater streams if they are deep enough. It is found to a depth of 150 meters (490 ft), but does not usually swim deeper than 30 meters (98 ft).


A bull shark's diet consists mainly of bony fish and sharks, including other bull sharks, but can also include turtles, birds, dolphins, terrestrial mammals, crustaceans, echinoderms,and stingrays.

Behavior Edit

Bull sharks are typically solitary hunters, but occasionally hunt in pairs. They often cruise through shallow waters. They can accelerate rapidly and can be highly aggressive, even possibly attacking a racehorse in the Brisbane River in the Australian state of Queensland. They are extremely territorial and attack animals that enter their territory. Since bull sharks often dwell in very shallow waters, they may be more dangerous to humans than any other species of shark, and along with the tiger shark, oceanic whitetip and great white shark, are among the four shark species most likely to attack humans.
