Common dolphins (Delphinus delphis) bowriding. Pod of short-beaked common dolphins riding the bow wave of a boat. Short-beaked common dolphins are found throughout the world in temperate and warm seas. They usually live in groups (or pods) of up to 100 individuals, but much larger groups are known to exist. They feed almost exclusively on fish, and may live for over 30 years. Photographed in the Gulf of California, Mexico.
