The bull shark is commonly found worldwide in warm, shallow brackish waters along coasts and in rivers; it may survive for significant periods in salt water. It is known for its aggressive nature. Bull sharks are large and stout, and can grow to 2.4 m (7.9 ft) long and 130 kg (290 lbs) as adults. Bull sharks have a bite force up to 5,914 newtons (1,330 lbf), among the highest of all investigated cartilaginous fishes.
This photograph, taken in Fiji, depicts a bull shark in the foreground with at least 20 other bull sharks in the deep blue background along with other reef fish.
