Animal Unique | Bull Shark | The bull shark, Carcharhinus leucas, also known as Zambezi sharks or unofficially known as Zambi in Africa and Nicaragua shark in Nicaragua, a shark often worldwide in warm, shallow waters along the coasts and in rivers. The bull shark is known for its unpredictable, often aggressive behavior. The Bull Shark is best known for his remarkable ability to thrive in both fresh and salt water and can travel far up the rivers. They are even known to get as far as the Ohio River in Indiana and Illinois in the Mississippi travels, though there are few recorded attacks. As a result, they are probably responsible for most of near-shore shark attacks, including many attacks attributed to other species. However, bull sharks are not true freshwater sharks (unlike the river sharks of the genus Glyphis).

Etymology Bull Shark
The name comes from bull shark pushed the shark shape, broad, flat snout and aggressive unpredictable behavior. In India, the bull shark confused with the "Sundarbans" or "Ganges shark." In Africa it is often called the "Zambezi Shark" or simply "Zambi." The wide range and diverse habitats result in many other local names, including "Ganges River Shark", "Fitzroy Creek Whaler", "Van Rooyen's Shark" , "Lake Nicaragua Shark", "river sharks", "freshwater whaler", "estuary whaler," "Swan River Whaler" "cub shark", and "shovel nose shark"
Distribution and habitat Bull Shark
The bull shark lives around the world in many different areas and travel long distances. It is common in the coastal areas of warm oceans, in rivers and lakes, and occasionally salt and fresh water flows when it deeply enough. It is found to a depth of 150 meters (490 ft), but not usually swim deeper than 30 meters (98 ft). The Atlantic Ocean is found from Massachusetts to southern Brazil and from Morocco to Angola. The Indian Ocean is found from South Africa to Kenya, India and Vietnam to Australia.
There are more than 500 bull sharks in the Brisbane River. One of them was reportedly seen swimming the flooded streets of Brisbane, Queensland, Australia, Queensland during the floods of late 2010/early 2011. Some were observed in one of the main streets of Goodna, Queensland, Australia, shortly after the peak of the January 2011 floods. There are still large numbers in the canals of the Gold Coast, in Queensland, Australia. A large bull shark was caught in the canals of Scarborough, two hours north of the Gold Coast. In the Pacific, the finding of Baja California to Ecuador.

The shark has traveled 4.000 kilometers (2.500 miles) up the Amazon River to Iquitos in Peru. It lives in freshwater Lake Nicaragua, the Ganges and Brahmaputra rivers of West Bengal and Assam in eastern India and neighboring Bangladesh. It can live in water with high salt content as in St. Lucia Estuary in South Africa. After Hurricane Katrina, many bull sharks in Lake Pontchartrain reported. Bull sharks are occasionally raised from the Mississippi River as early as Alton, Illinois. They are also found in the Potomac River in Maryland
Freshwater tolerance Bull Shark
The bull shark is the most famous of the 43 species of elasmobranch in ten genera and four families have been reported in fresh water. Other species include the rivers are stingrays (Dasyatidae, Potamotrygonidae and others) and sawfish (Pristidae). Some skates (Rajidae), smooth Dogfish (Triakidae), and the sandbar shark (Carcharhinus plumbeus) regularly enter estuaries. Cartilaginous Fishes' ability to fresh water to go is limited because their blood is usually at least as salty (in terms of osmotic strength) and seawater by the accumulation of urea and trimethylamine oxide, but bull sharks live in fresh water the concentration of these solutes to reduce by 50%. As a result, bull sharks live in fresh water to produce twenty times more urine and in salt water.

At first scientists thought the sharks in Lake Nicaragua was part of an endemic species, the Lake Nicaragua shark (Carcharhinus nicaraguensis). In 1961, following specimens equations, taxonomists synonymized them. They can jump through the rapids of the San Juan River (that connects Lake Nicaragua and the Caribbean), almost like salmon. Bull sharks tagged in the lake were later caught in the open ocean (and vice versa), with a minimal number of seven to eleven days to complete the journey
Anatomy and appearance Bull Shark
Bull sharks are large and stout, with women who are larger than males. The bull shark can reach up to 81 inches (2.66 meters) in length at birth and grow to 3.5 meters (11 ft) (although a 13-footer was caught in a South African river) and weighs 318 kg (700 lb) . Bull sharks are wider than other sharks requiem of similar length and are gray above and white below. The second dorsal fin is smaller than the first. According to the National Geographic program Animal Face-Off, bull sharks have a bite force of up to 567 kilograms (1,250 lb)

Behavior Bull shark
Bull sharks are usually solitary hunters, but sometimes hunt in pairs. They often cruise through shallow waters. They can accelerate quickly and can be very aggressive, maybe even a horse to fall into the Brisbane River in the Australian state of Queensland. They are very territorial and attack animals that enter their territory. Because bull sharks often dwell in shallow waters, they more dangerous to humans than other species of sharks and, along with the tiger shark and great white shark, among the three species of sharks are most likely to attack humans.

One or more bull sharks may have been responsible for the Jersey Shore shark attacks of 1916, which was the inspiration for Peter Benchley's novel Jaws. The speculation of the bull shark may be responsible based on a number of attacks that occur in brackish and fresh water but that there are certain similarities in bite marks between the bull and great white sharks.
The bull shark is responsible for bombings around the Sydney Harbour inlets. Most of these attacks were previously attributed to great white sharks. In India, bull sharks swimming the Ganges and the people attacked. Many of these attacks are attributed to the Ganges shark, Glyphis gangeticus, a critically endangered river sharks which is probably the only other shark in India who can comfortably live in fresh water, although the gray nurse shark was also blamed in the sixties and seventies .
