Dolphins are carnivores. They eat a variety of fish, especially flying fish. Catching these flying fish sometimes requires the dolphins to leap out of the water.
Dolphins are aquatic mammals. There are over 50 species of dolphins, including 12 freshwater species. The common dolphin and bottle-nosed dolphin are the best known species. They possess a fish-like form and hairless body, and they constantly shed their sleek skin to avoid external parasite accumulations. A protective layer of blubber shields them from cold, and they breathe air through a dorsal blow hole. Their tail fins propel them through the water, while their fore fins and dorsal fins steer.
