What kind of food can you fit into your mouth? Do you know of a fish with a big mouth that likes to eat only tiny sea creatures? Learn some facts about sharks that might surprise you! But be careful!
You saw a picture of a shark!
All sharks are fish.
Sharks live in water. They have gills that allow them to breathe underwater. The gills are the slits on the side of their head.
Point to where the gills are:
Not all sharks are dangerous to people.
Out of the four hundred different types of sharks, only thirty different types of sharks have been known to hurt people. Most sharks are not dangerous, but some are!
You always need to be careful when you are around an area where sharks might live. Even though not all sharks are dangerous, you don't want to have a run-in with a dangerous shark like a great white shark!
Remember, sharks are fish. This means they have gills that allow them to live underwater, and they spend their entire life underwater.
Most sharks live in the ocean, but there are also sharks that live in fresh water. A bull shark is a common freshwater shark.
Sharks have a very strong sense of smell. This helps them hunt for animals.
Even when the water is cloudy, dirty, or dark, a shark can sniff out its prey.
Sharks are carnivores. This means they only eat meat.
They eat fish, dolphins, seals, and many other sea animals.
They bite with their lower jaw first, then their upper jaw. This is how they hunt their food.
Most sharks swallow their food whole. Sharks have teeth that grow back. If a shark loses a tooth, a new one will grow in its place.
Sharks have babies in different ways. Some sharks lay eggs, some sharks hatch inside their mother and then are born, and some sharks give birth to live babies that grew inside of them.
A baby shark is called a pup. After the babies are born, the mother leaves the baby shark behind, and it has to survive on its own.
