Sharks often get a bad reputation because people don't understand a lot about them. Learn some interesting facts about sharks in this lesson to see just how fascinating they really are!

What Is a Shark?

While swimming in the ocean, you spot a fin in the distance. What is it? Should you be scared? What you may have seen is the fin of a shark. Let's learn about these mysterious creatures!

A shark is a type of fish that has a skeleton made of cartilage, which is a flexible tissue softer than bones. Your ears and nose have cartilage in them, which is why you can bend them around! There are over 400 types of sharks in the world, and they can range in size from only a few inches to 40 feet long, like the whale shark. That's almost as big as a school bus!

The whale shark is the largest shark in the ocean. It can be up to 40 feet long!

Where Do Sharks Live?

Since there are many types of sharks, you can find sharks in many different places around the world. The majority of sharks live in saltwater. Some live in shallow, warm waters, while others live in the cold, deep, open ocean.

All sharks are able to breathe in the water using a special organ called gills. Most sharks need to stay swimming in order to pass water over their gills, which is how they get oxygen.

What Do Sharks Eat?

Sharks are carnivores, which means they eat other animals. This includes fish and even large mammals like sea lions.

Sharks are known for their sharp teeth and unique jaws. They are able to move both their upper and lower jaws, unlike us (we can only move our lower jaws)! Sharks are also able to grow back their teeth anytime they lose them. We can do this when we lose our baby teeth, but not after that!

Sharks come in many sizes, but they are all types of fish.
