Bull sharks have a rare ability to be able to survive in freshwater.


Bull Shark Facts

All sharks evolved from the ocean and they must keep salt in their bodies to survive. When in fresh water, most saltwater fish would die because their salty bodies would absorb the water and continue to absorb it until they blew up like a balloon.

Vise Vera, if you put a freshwater fish in saltwater, their bodies would shrivel up and die as the salt would absorb all of their body fluids.

The bullshark is able to survive this because a process called osmoregulation. This allows them to control the movement of salt solution through a special adaptation in their kidneys, which work overtime when they are in fresh water.

So instead of blowing up like other fish, these sharks excrete the excess water in their urine, which means they pee… a LOT.

People have spotted bull sharks thousands of miles up the Amazon River in South America…far from the sea. Bull sharks have also been found swimming in the Mississippi River as far north as (Alton)Illinois as well as upstream in many other rivers around the world.

Currently there have been 104 recorded bull shark attacks in the last 150 years, and out of those, 33 fatalities.
