Sharks Have to Constantly Keep Moving to Stay Alive

When people think of sharks, they usually think of dangerous sea creatures with a lot of sharp teeth. However, sharks are so much more than that.

There are lots of different types of sharks, and all of them are different sizes. Some of the most common sharks are the hammerhead shark, blue shark, tiger shark, and the great white shark. Tiger sharks usually grow up to 20 feet long. Great white sharks can grow even larger than that. Some of the biggest sharks can even reach more than 46 feet in length.

Sharks have a massive amount of teeth. They can have up to eight rows of teeth. On average, sharks lose and regrow 30,000 teeth in their lifetime. They also often have sucker fish, a cleaner fish that can eat the lice in its skin.

Sharks eat many different things. Their diet can range from fish, clams and shellfish, to garbage and even land animals that made it into to the water.

Sharks are constantly moving throughout the water. They have to keep swimming, because if they stopped, they wouldn't be able to float.

Sharks are used for many things around the world. Shark meat is considered a delicacy in some parts of the world, like China. Their skin can be used to make leather, fertilizer, oils and vitamin A.

Sharks are amazing animals that often get a bad reputation. While some sharks can become dangerous if provoked, most sharks rarely encounter humans and are pretty cool creatures.
