You're 70 feet underwater-face to face with one of the sea's friendliest creatures. National Geographic photographer Flip Nicklin and his wife Linda, a naturalist and educator, invite you to study the amazing behaviour of the beloved dolphin.

Learn the difference between an orca and a bottlenose. Witness a dolphin baby nursed with mother's milk. Discover how these social mammals echolocate and communicate. Flip is a veteran of 5,500 dives worldwide, and this compelling book aims to encourage active concern and support for these smiling sea creatures whose intelligence demands our kinship.
