dolphin
dolphin Family of small-toothed aquatic whales, there are salt and freshwater species. The best-known are the dark blue-backed common dolphin, the blue-grey bottle-nosed and the killer whale. Larger than a porpoise, a dolphin has a distinct beak and slender body, a tail fin for propulsion, and a dorsal fin for steering. A dolphin breathes through a single blowhole, and can remain underwater for 15 minutes. It is the fastest and most agile of the whales, achieving speeds up to 39km/h (24mph) and leaps of 9m (30ft). Dolphins swim in large, hierarchically organized schools, feeding on fish and crustacea. Their intelligence and playful behaviour have contributed to a wealth of maritime literature and mythology. They communicate through a complex language and map their environment by echolocation. Dolphins have a gestation period of 12 months, and the mother nurtures her calf for the first two years of life. Length: to 4m (13ft). Family Delphinidae; species Tursiops truncatus.
