Scuba diver finds herself in a pack of intimidating bull sharks

Bull sharks are large, powerful sharks that have little fear of anything. They are known for their aggressive nature. They are one of the few species that can thrive in both salt water and fresh water. They are believed to be responsible for the majority of near shore attacks on humans. The average length of a female bull shark is 2.4m (8 feet) with the largest recorded being 4m (13 feet). Typically, the maximum weight can reach 600kg (1300lbs). With a bite force up to 5,914 newtons, they rank among the most capable biters of all fish.
Bull sharks inhabit many coastal waters and inland rivers, with several sightings in flooded canals and streets in Australia. There are even a few bull sharks in a golf course lake in Carbook, Logan City, Queensland, Australia.
