Guide to marine mammals of the world /

Covers 120 species of whales, dolphins, porpoises, seals, and sea lions. Information about each species covers every aspect of the animal's anatomy, life cycle, and behavior. The guide delineates evolution, worldwide population, migratory routes, and habitats, and describes feeding habits, vocalizations, social organization, surface behavior, and threats to and chances for survival. The text for each animal is accompanied by up to three richly detailed full-color paintings by marine artist Pieter Folkens, full-color photographs illustrating typical behavior, and a map indicating the species' range and migration. Additional maps give water temperatures, ocean currents, and ocean floor geography. "Watching" guidelines include identification techniques, where and when to go, and how to deal with a stranded animal.
