There is more ocean covering the Earth than land. And you can find sea creatures in almost every drop of it—shallow and deep, icy and warm. There are monster mammals bigger than any animal ever to have lived living next to tiny creatures so small that you can’t even see them without a microscope. Scientists have hardly begun to count all the different kinds of fish. The smallest, the dwarf goby, would fit on your fingertip. The largest, the whale shark, weighs as much as six elephants. Strangely, the giant whale shark’s diet includes some of the sea’s tiniest creatures, which are called plankton.

7 Check out the whale shark’s huge, gaping mouth! Inside are 300 rows of tiny teeth. But it doesn’t use those teeth to hunt—it is a filter feeder.
