Toothed whales have teeth and prey on fish, squid, other whales and marine mammals. Like all mammals, whales breathe air into lungs, are warm-blooded, feed their young milk and have some (although very little) hair. Their bodies resemble the streamlined form of a fish, while the forelimbs or flippers are paddle-shaped. The tail fins, or flukes, enable whales to propel themselves through the water. Most species of whale have a fin on their backs known as a dorsal fin.
