Not all sharks eat people

Here is a person petting a shark. This shows that not all sharks eat people.

Sharks in General

Shark Hearing
Sharks have extremely sensitive hearing. They can identify much lower sounds than human ears can detect, and some can hear sounds more than 700 feet away. Some scientists think hearing is typically the first sense sharks use in detecting their prey.

Shark Smelling

Smell, however, could be the most remarkable of the sharks' senses. Some sharks may be able to track their prey by smell from up to a mile away, probably by following a trail of microscopic particles of protein or blood.

Shark Babies

Different sharks have their babies, or "pups," in different ways. Some lay egg cases. Others grow the pups inside of them and give birth to live young. Depending on the species, a shark may give birth to one or to dozens of pups! However it is born, a pup is on its own from the start—the mother shark doesn't stay around to take care of it.

Shark Evolution

Scientists think that ancestors of sharks lived more than 400 million years ago—about 200 million years before dinosaurs. The main types of sharks living today evolved by 100 million years ago.

Shark Teeth

Most sharks have at least four rows of teeth. They don't chew—they use their powerful teeth to bite and tear their food. As the first row of teeth in a shark gets worn out, the other rows of teeth move forward. New teeth are always forming.

Shark Predators

Sharks rarely pose a danger to humans. But humans do pose a danger to sharks! Fishermen kill an estimated 30 million to 100 million sharks every year. About 75 shark species are in danger of becoming extinct.

Basking Shark

 The basking shark is the second largest fish in the world. These sharks can grow up to a length of ten meters, but, some of them have a body length of 11 to 13 meters too. An average adult basking shark can have a body weight of around 9000 pounds (4 tonnes). A distinct feature of these sharks is the five big gill slits on the either side of the head. The gill slits runs from the top to the bottom of the head. These gills have thousands of bristle-like gill rakers, that help them to filter the food floating in the water. These gill rakers are shed periodically.
