About the Nursehound

Sharks have lived in our oceans for 450 million years. These animals already made their way through the oceans long before dinosaurs populated the earth. Their brains developed further during this long period: they became more intelligent, their senses more pronounced - especially their sense of smell. There are over 440 species of sharks.

• Shark attacks: Every year more people die in a lightning storm, volcanic eruptions or because they fall out of bed than they do by a shark attack.
• Pretty clever: Some still unhatched baby sharks sense when predators swim by. They protect themselves by playing "dead" in their egg.

The big spotted cat shark likes it quiet: During the day it rests on the ocean floor. At night it becomes active and swims into deeper water layers for hunting.
