Question

Which part of the body helps the bull shark survive in freshwater?

Answer 1

The bull shark is able to survive in freshwater due to its ability to regulate the amount of salt in its body. This is done through specialized glands located near its kidneys that help to maintain the right balance of salt in its blood.

Answer 2

The bull shark has special glands in its kidneys that allow it to adapt to freshwater environments. These glands help the shark to recycle salt in their bodies, which is necessary for maintaining proper osmotic balance. As a result, bull sharks are able to swim and thrive in rivers and lakes.
