MEGA SHARKS

Sharks are beautiful creatures. Sharks are fish that live in oceans all around the world. 
They have been around since before the dinosaurs!

There are about 400 species (types) of shark. They are not all of the same size. For example, the dwarf lantern shark is only about 16cm long while to whale shark is gigantic and can grow up to 12m long.

Their skin is harsh and is made of tiny sharp scales. These scales are made of the same material as our teeth.

The baby of a shark is called a pup. Some species lay their egg in a mermaid purse. This is a strong pouch which keeps the egg safe from predetors. Other species give birth to live pups.

The Leopard Shark

The leopard shark has different kinds of spots on its body. 

They hunt for food during the night and they rest on the sandy ocean floor during the day. 

Whenever scuba divers try to touch it, this shark swims away from them. Its coat is nearly the same colour as sand. It uses camouflage to catch ts prey.

The Great White Shark 

 The great white shark is one of the largest and most famous sharks in the world.

We may have heard about these sharks attacking people however this is very rare. When these sharks attack people it is because they mistake them for their usual prey.

This sharks favorite food is made up of seals, dolphins, turtles and other sharks.
The great white shark can have up to 30,000 teeth during its life. Whne they lose a tooth another moves to take its place.

This mega fish is actually grey and white. The white part is its belly. The top part is grey and this helps it not to be seen when it swims under its prey.

Its teeth are jagged at the edges on both sides. This gives it the perfect grip on its prey.

Unfortunately some species of beautiful sharks are now endangered. People catch them either for sport or for food. People use their jaws as trophies, or for shark fin soup.

Also dirty sea is becoming a huge propblem for sharks. Pollution damages the coral reefs and sharks need these reefs to feed, live, breed and grow.

Now we know what amazing creatures sharks are. We have to do all that we can to keep our seas clean and help them be healthy.
