cetacean or whale any aquatic EUTHERIAN mammal of the order Cetacea, comprising the porpoises, dolphins and whales. Cetaceans are completely aquatic, have lost their hind limbs during evolution and have fin-like forelimbs, often a dorsal fin and, in marked comparison with fishes, a blowhole and transverse tail fin. The young are large at birth and suckled like other mammals. Cetaceans possess an extensive outer layer of fat associated with their marine habit, have a large brain and are capable of complex communication. cetacean Related to cetacean: whaleSynonyms for cetaceannoun large aquatic carnivorous mammal with fin-like forelimbs no hind limbs, including: whalesSynonymsRelated Words- aquatic mammal
