Description

Common dolphins are colorful complex crisscross pattern on their side. They feed primarily on fish and squid and often hunt cooperatively using echolocation. They are fast swimmers, reaching speeds of 25 miles per hour.

Common dolphins are very social and can be seen in pods of several hundred individuals and occasionally in megapods of more than 1,000 individuals.

While not endangered, common dolphins are vulnerable to pollution and are accidentally caught in fishing gear including gillnets and shrimp trawls.
