Cetacea
Whales, dolphins, porpoises; order of marine mammals comprising two extant suborders, Odentoceta (toothed whales) and Mysticeta (baleen whales); body fusiform, forelimbs modified as flippers, hindlimbs absent, tail bearing lateral flukes; nares dorsal; eyes small, pinnae absent; skin essentially hairless with thick layer of subcutaneous fat for insulation.
cetacean
Any of various wholly aquatic placental mammals belonging to the order Cetacea, which includes the dolphins, porpoises, and whales. Their bodies are fish-shaped and adapted for swimming, with forelimbs in the form of paddlelike flippers. Functional hindlimbs are not seen. The long tail ends in two tranverse flukes, horizontally flattened tail used for locomotion. Hair is found only on the muzzle. There is a thick layer of fat (blubber) beneath the skin.
cetacean mammal

mysticete, mysticetous
