Although different types of sharks can look very different from one another, they also have many important characteristics in common.

A Tropical Shark

The sharks are what most people think of as tropical shark. They have steam-lined bodies, which means that their shape allows them to slip easily through the water.

Shark Skin

A shark's skin is covered in tiny, thorn-like hooks called Denticles, which feels rough to the touch. These help to protect the shark from injury.

Fin Features

A shark's fin are among its most important features. Where many animals have pair of front and back legs, sharks have a pair of pectoral and pelvic fins. Fins help sharks to balance and change direction in the water. Sharks are the best known for the dorsal fin, or fins, on their backs, which can sometimes be seen poking above the sea surface.
