Flipper (anatomy) structure on cetaceans is called the "dorsal fin" and the large cetacean tails are referred to primarily as flukes but occasionally as "caudal fins". Some flippers are very efficient hydrofoils, analogous to wings (airfoils), used to propel and maneuver through the water with great speed and maneuverability (see Foil (fluid mechanics)). Some flippers are less foiled, with the appendages still apparent, as in the webbed forefeet seen in amphibious turtles. Flipper (anatomy) A flipper is a typically flat forelimb evolved for movement through water. Various creatures have evolved flippers, for example penguins (also called "wings"), cetaceans (e.g. dolphins and whales),
