A shark is a predatory animal. It’s a large type of fish that has a reputation for being dangerous.


Sharks are often identified by a large dorsal fin, visible when swimming close to the surface of the water.

Sharks are feared and admired for their killer instincts. Of course, like all fish they have to eat, and as they sit at the top of the food chain, their prey are other fish or mammals such as seals and sea lions. Sharks rarely eat people, but they are known to attack a lone swimmer from time to time.


When a person is associated with the word "shark," it usually means the person preys on other people. (prey = feed upon)
