Dolphins: Delphinidae


Dolphins are carnivores, meat eaters. They eat fish and squid and capture their food one fish at a time. The type of fish they prefer depends on the zone of the ocean that they inhabit. Killer whales eat fish, but they also hunt seals, sea lions, other dolphins, whales, porpoises, and sea birds.

Dolphins use echolocation to navigate and find prey. Echolocation allows dolphins to use high-pitch sounds that bounce off objects in order to determine their location. In some species, echolocation is so sensitive that it can locate an object less than 0.5 inch across (1.25 centimeters) at a distance of 50 feet (15 meters).
