Where do bull sharks go in the winter?
On the east coast of the United States, bull sharks migrate as far north as Massachusetts when the waters are warm, returning south to subtropical and tropical coastal waters as the water becomes cooler. They also migrate from the ocean up freshwater rivers in several areas of the world.
Do bull sharks travel?
Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean.
What is a bull sharks habitat?
Bull sharks are found in coastal waters all over the world. In the United States they are found off the East Coast and in the Gulf of Mexico. Unlike most sharks, bull sharks can survive in freshwater for long periods of time. They have even been found in the Mississippi and Amazon Rivers.
Do Bull sharks migrate?
Bull sharks occur in tropical to subtropical coastal waters, worldwide. In the western Atlantic, bull sharks migrate north along the coast of the U.S. during summer, swimming as far north as Massachusetts, and then return to tropical climates when the coastal waters cool (Simpfendorfer and Burgess 2009).
Do great white sharks migrate?

What is the life cycle of a bull shark?
Bull sharks reach sexual maturity between the ages of 8 and 10. They breed in brackish waters in summer months. Females give birth to a litter of between one and 13 live young after a 10 to 11-month gestation period. Bull sharks can live to be at least 14 years old.
Is it true that bull sharks hunt alone?
Most hunt alone, but researchers have spotted bull sharks hunting in packs on occasion. As discussed above, bull sharks do frequent many of the same areas that humans do. Because of this, they are responsible for large numbers of shark bites. They hunt in murky water, so it is difficult to see them approaching.
What kind of environment does a bull shark live in?
Bull sharks in freshwater environments decrease the salt-excretory activity of the rectal gland, thereby conserving sodium and chloride. The kidneys produce large amounts of dilute urine, but also play an important role in the active reabsorption of solutes into the blood.
How is the bull shark able to conserve energy?
Energy conservation. An interesting find was that the movement was directly related to the bull shark conserving energy for itself. One way the bull shark is able to conserve energy is that when the tidal flow changes, the bull shark uses the tidal flow in order to conserve energy as it moves downriver.
Are there any natural predators for bull sharks?
Bull sharks have no natural predators in the wild, in fact humans are their biggest threat. Larger sharks, such as the tiger shark and great white shark, may attack them, typically only targeting juveniles however. Crocodiles may be a threat to bull sharks in rivers as well.
