whale : any of various very large, aquatic, marine mammals (order Cetacea) that have a torpedo-shaped body with a thick layer of blubber, paddle-shaped forelimbs but no hind limbs, a horizontally flattened tail, and nostrils that open externally at the top of the head — Webster See also OneLook
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. — Wikipedia
Biology is the scientific study of life. Biologists study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. Biologists also study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. — Wikipedia

Three researchers, one with the University of Michigan, the other two with the University of Casablanca, have found a skull and partial skeleton in Morocco that they suggest link together several species of ancient whales. In their paper published in the open access journal PLOS ONE, Philip Gingerich, Ayoub Amane and Samir Zouhri describe the fossils and how they tie together the evolution of land-based creatures that evolved into modern whales.
