  1. Creature Feature

  2. Cookie Cutter Shark

  3. Small, rarely-seen dogfish shark • Cigar-shaped body • 20 inches in length • Large eyes with green pupils • Live from the surface – 11,500 ft deep

  4. Inhabits warm, deep waters of equatorial oceans, primarily in coastal waters near islands • Inhabit deep water during the day and migrate into surface waters at night

  5. Adaptations • Bioluminescent belly • Glows a pale blue-green that matches the background light from the ocean's surface • Serves as camouflage to creatures beneath it • Has a small non-luminescent patch (appears black) • Deceives the shark's prey, smaller predatory fish (like tuna), into thinking the shark is an even smaller fish

  6. Feeding • Derives its name from the shape of the bite marks it makes in its prey • Removes small circular plugs of flesh and skin from cetaceans and large fish • Attaches with its suctorial lips and modified pharynx • Then rotates its body to achieve a round, symmetrical cut

  7. Conservation • Listed as a species of Least Concern by the IUCN • Not really a threat to humans • Occasionally mistake man-made objects for prey • Submarine's rubber sonar dome
