1.Bull Sharks Facts Regarding Their Habitat
Bull sharks have inhabited the oceans for 420 million years. They can be found in warm-water coastal areas with a special presence in the tropics.

How Is It Possible? Osmoregulation is another bull sharks fact.
Osmoregulation is a fish process to regulate their salt and water flows. This phenomenon helps them to keep their internal condition stable, regardless of the water in which they swim. The kidneys, liver, and rectal gland of bull sharks can gradually adjust to the salinity of the water in which they are. When they move into fresh water, their kidneys process much more fluid, barely getting rid of the salt it contains. They eliminate the extra urea by the urine.
