The cookie-cutter shark is named for the way it cuts a wound in whales, dolphins, seals and large fish. It grips the sides of its prey with fierce jaws and gouges out a circular, cookie-shaped piece of flesh. In this photograph, new teeth along the lower jaw are ready to replace the existing ones before they wear out. Other sharks also have this feature.
