Shark Facts
There are almost 400 different kinds of sharks. Some sharks are longer than a school bus, while others are so small they can live in fish tanks. Sharks come in all kinds of colors. Most of the time, their skin color helps them to camouflage.
Most sharks live in saltwater, but some can live in freshwater. Sharks are actually a type of fish. Like other fish, sharks have gills. Gills are how fish breathe. Water needs to move over the gills so that sharks get enough oxygen. To keep the water moving, most sharks need to swim in water that has a very strong current.
Sharks have lots of teeth that are arranged in many rows, rather than in just one row like people. The teeth from the outside row gradually fall out, and teeth from the next row take their place. Some sharks will lose 30,000 teeth in a lifetime! Each species of shark has different kinds of teeth. This is because different sharks eat different kinds of food. Some sharks eat food as small as plankton while other sharks eat animals as big as sea turtles. Most sharks do not eat very often. Some sharks will even go weeks between meals!
