There are almost 400 different kinds of sharks,and they can be found in all four oceans of the world.
Each kind of sharks looks different.Some are longer than a school bus,while others are so small that they can live in fish bowels.Sharks come in all kinds of colors.Most of the time,their colors help them fit in with their surroundings.
Sharks have many rows of teeth,rather than just one row like man.The teeth from the oustside row gradually fall out,and the teeth from the next row take their place.Some sharks will lose 30,000 teeth in a lifetime!Different types of sharks have different kinds of teeth.This is because different sharks eat differrent 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 go weeks vetween meals.Sharks are at the top of the ocean food chain.That is to say no animals can hunt them for food.
One of the most special things about sharks is that they have been around for a long time.Sharks have livd in the sea for about 64 million years!And scientists believe they have not changed much since then.How amazing it is!
Sharks are very different animals,and there are still many things people can learn about them.
