Sharks are fish that have been swimming in the ocean for millions and millions of years! They were here even before the dinosaurs. Sharks are great hunters with super senses that help them find food in the water. There are more than 500 different kinds of sharks in the ocean!
Sharks have smooth, strong bodies shaped like torpedoes that help them swim super fast. They have rows and rows of sharp teeth, and when a shark loses a tooth, a new one grows right back! Sharks come in many sizes — some are as small as your hand and some are as big as a school bus. Most sharks are gray or blue on top and white on their belly.
Sharks live in oceans all around the world, from warm tropical waters to cold seas near the poles. They eat fish, squid, and other sea creatures. Some big sharks like great whites eat seals too! Sharks are always swimming because most of them need to keep moving so water flows over their gills and they can breathe.
The whale shark is the biggest fish in the whole ocean, but it only eats tiny little creatures called plankton!
Sharks can smell a tiny drop of blood in the water from far away.
A shark can grow thousands of teeth in its lifetime.
Sharks do not have any bones in their body — their skeleton is made of a bendy material called cartilage, just like the tip of your nose!
