How does the huge whale shark eat?

The gentle whale shark is a filter feeder, straining tiny plankton and small fish from the seawater.

What special sense helps sharks detect prey's electricity?

Jelly-filled pores called ampullae of Lorenzini let sharks sense the faint electricity living animals give off.

Why are sharks important to the ocean?

As top predators, sharks keep other animal populations balanced and healthy, so oceans depend on them.
