Sharks are amazing creatures. They are known as the deadliest hunters in the sea. Fortunately most are not, but there are some kinds of sharks that can be extremely dangerous. Look at these

short descriptions of four kinds of sharks

The Great White Shark

Great Whites are one of the most frightening creatures in the sea. They live in tropical and subtropical waters, and they can grow up to 9 meters long. Most Great Whites are actually grey, blue or brown with a white belly, and their powerful teeth are triangles with edges like saws.

The Whale Shark

Whale Sharks are the largest kind of shark in the world - up to 11 meters in length. They live in tropical waters all around the world, but they are not dangerous. Whale Sharks are brown or grey with white or yellow stripes. They often travel near the surface of the sea.

The Mako Shark

Mako Sharks are fierce predators. They come from the same family of sharks as the Great White and they are especially fast - they can swim at speeds of up to 65 kilometers per hour. They are large bluish sharks found in the Atlantic, Pacific and Indian oceans. Mako Sharks can grow up to 3 meters long.

The Great Hammerhead Shark

The Great Hammerheads' most striking feature is its wide thick head which looks like a hammer. The average size of a Great Hammerhead is approximately 3. 5 meters, but can grow up to 6 meters long. These sharks average over 500 pounds but can weigh as much as 1 ,000 pounds. Like most sharks the females are larger than the males. They have several rows of teeth that have 24 to 37 teeth per row. The Great Hammerhead has a very keen sense of smell, which helps find its prey.
