The bottlenose dolphin is found along almost all tropical and temperate coasts, and offshore varieties also exist in deep water. They eat fish, shrimp, squid, and other invertebrates. Dolphins appear to stay mated for life. They communicate using a variety of whistles and rasping sounds and can discriminate even small objects by echolocation—that is, they send out high-frequency clicks that bounce off prey and other objects, and then use the returning echoes to distinguish the objects. Dolphins sometimes stun their prey with high-pitched clicking sounds. Is it any surprise their brains are larger than those of humans?7/21/2007
