The term 'whalelike mammal' can be summarized by the 6-letter word 'DUGONG'. The DUGONG is a large marine mammal that is closely related to manatees and sea cows. It is found in warm coastal waters of the Indian and western Pacific Oceans, and is the only strictly herbivorous marine mammal. The DUGONG has a fluked tail and paddle-like forelimbs, which are characteristics of whales, hence its classification as a whalelike mammal.
