In this game, students match features to the appropriate animal, and evaluate how those features help it survive.
Animals have more than one special feature to help them survive. Animals that live in the same sort of conditions may have evolved similar features. For example, most mammals that live in the northern Pacific Ocean (whales, sea lions, seals) grow a thick layer of blubber under their skin to insulate the muscles and organs of their body from the cold. Sea Otters have developed another evolutionary path to the same end. These mammals do not have a layer of blubber; instead they have very thick fur that they blow air into to create a layer of insulation.
