Common bottlenose dolphins are the most familiar dolphins due to the wide exposure they receive in captivity in marine parks and dolphinaria, and in movies and television programs. They inhabit temperate and tropical oceans throughout the world, and are absent only from polar waters. Their diets consist mainly of eels, squid, shrimp and wide variety of fishes. They do not chew their food, instead swallowing it whole. Dolphin groups often work as a team to harvest schools of fish, though they also hunt individually. Dolphins search for prey primarily using echolocation, which is a form of sonar.
