In the West Atlantic, you can find Bull sharks off the coast of Massachusetts, United States and south to Brazil. In the East side of the Atlantic Bull shark off the coast live Morocco and from Senegal to Angola. Bull sharks are also found in the Indo-West Pacific region where it occupied the territory of Kenya and South Africa to India, and farther to the waters around Australia and Vietnam. At the West side of South America-North and Bull shark life from southern Baja California in Mexico and Ecuador. Bull shark may also have been seen off the coast of Peru, but this is still not confirmed.

Bull sharks prefer to live near the coast and live in shallow waters such as bays and estuaries. To be able to survive in fresh water it will often swim rivers and streams, and even in the lake. Bookmark and especially young sharks found fresh water and is sometimes found hundreds of kilometers from the sea in rivers and streams. Sharks, Bull sharks prefer adult district where freshwater rivers flow into the sea, such as river deltas and estuaries. Silver sharks rarely dive deeper than 30 m and are usually found in shallow waters where many only a few meters depth. This preference for shallow waters very close to the coastline and the bay silence means that Bull sharks must share their habitat with humans in much of the world. This is also why the Bull shark is considered one of the most dangerous shark species and has been involved in a series of attacks on humans. Bull sharks must always approach with caution, and preferably not exposed and bothered at all if possible. Reputation as devil man eating animals but really not qualified.

One litter usually consists of 1-13 small fish and young Bull shark is usually about 60 cm at birth. Delivery time depends on the habitat female Bull shark. For example,female Bull sharks live from Nicaragua can give birth year rotation, with the number of births peaked in spring and early summer. Bookmark and women who live sharks off the coast of South Africa on the other side will only give birth in late spring or early summer. The same is true for women Bull sharks living in the western North Atlantic off Florida or the Gulf of Mexico. The minimum population doubling time for Bull sharks more than 14 years.
