Experts best know the appropriately named Bull Shark for its aggressive nature. In fact, this species appears responsible for the majority of shark attacks worldwide.
It constitutes one of the best-known types of requiem shark. This ocean dweller is also highly adaptable to environmental conditions. Actually, it is one of the few saltwater sharks actually capable of living in freshwater for extended periods of time.
They are also deceptively powerful. Relative to body mass, this apex predator has the most powerful bite of any known cartilaginous fish.
Bull Shark Physical Characteristics
Though not overly large, the body of the Bull Shark is relatively stout in design. A slight degree of sexual dimorphism is also present in this variety of Requiem Shark. The females average approximately 7.9 ft (2.4 m) in length and about 290 lb (130 kg) in weight. The males are slightly smaller in size and commonly attain a length of circa 7.4 ft (2.25 m), and weight of 210 lb (95 kg).
The fins usually display a dark tip.
Bull Shark Distribution, Habitat, and Ecology
The Bull Shark is common throughout the warm oceans of the world. Unfortunately for humans, they also live in many rivers and lakes. In the ocean, they prefer shallow areas near coastlines and rarely inhabit depths of more than 490 ft (150 m).
They have even been spotted as far inland as 2,500 mi (4,000 km) up the Amazon River.
As with other sharks, the Bull Shark is an opportunistic hunter. They typically hunt alone, however. Their principal prey is bony fish, but they will also consume turtles, dolphins, birds, terrestrial mammals, and even other small sharks.
They are certainly apex predators within their habitat and have few natural predators themselves. Their principal threats are from commercial fishing.
The IUCN has them listed as Near Threatened.
