  • 1. The <br /> Vampire <br /> Squid<br />Jordan Masluk<br />Melinda Souvannara<br />Period 5<br />Vampyroteuthis infernalis<br />
  • 2. Hypothesis<br />How has the Vampire Squid been able to survive since prehistoric years?<br />
  • 3. What is it?<br /><ul><li>Small, deep-sea cephalopod
  • 4. Shares similarities with both squids and octopuses
  • 5. Only known surviving member of its order
  • 6. First described and originally classified as an “octopus” in 1903 by German teuthologist Carl Chun </li></li></ul><li>What it looks like<br /><ul><li>Max of 30 cm (1 foot) in length
  • 7. 15 cm (6 inch) gelatinous body
  • 8. Varies in color between velvety jet black to pale reddish
  • 9. Eight arms
  • 10. Lined with rows of fleshy spines
  • 11. Inside of it’s “cloak” is black
  • 12. Red or blue eyes
  • 13. Ear-like fins projecting from lateral sides
  • 14. serve as primary means of movement- propulsion
  • 15. fly” though water by flapping fins
  • 16. Beak like jaws are white </li></li></ul><li>How it has survived<br /><ul><li> Lives in the aphotic (lightless) zone from 2000-3000 ft also known as the oxygen minimum zone (OMZ)
  • 17. In the OMZ the saturation is too low to support metabolism in most higher organisms
  • 18. However, the Vampire Squid can live and breathe normally in this zone at oxygen saturations as low as 3%
  • 19. Live where humans cannot go without a submarine
  • 20. Covers itself in its “cloak” when agitated to blend in with surrounds and become almost invisible
  • 21. In order to survive such suffocation depths
  • 22. Has a very low metabolic rate
  • 23. Can go for long periods without food
  • 24. Successful because food can be very hard to find at such extreme depths</li></li></ul><li>How it has survived cont.<br /><ul><li>Gills have large surface area
  • 25. Have blue blood hemocyanin binds that transport oxygen throughout body more efficiently
  • 26. Have weak musculature
  • 27. Maintain agililty and buoyancy by statocysts and ammonium rich tissues that match density of surrounding seawater
  • 28. Have highly sensitive eyes that are able to distinguish silhouettes of other animals moving above
  • 29. Generates its own bluish light (bioluminescence)
  • 30. Can last about 10 minutes
  • 31. Used to distract predator while the squid disappears in the darkness
  • 32. Pair of photoreceptors located on top of its head
  • 33. alerting the animal to movements above
  • 34. If threatened (instead of inking like octopuses) a sticky cloud of bioluminescent mucus is ejected from the arm tips</li></li></ul><li>Fun facts<br /><ul><li>Vampire squids are carnivorous and feed on copepods, prawns and Cnidarians
  • 35. They swim around in circles trying to catch prey
  • 36. Did you know vampire squid are not squid nor octopus, they belong to a family with themselves-Vampymorpha
  • 37. It has the largest eyes of any animal on the earth
  • 38. They create complex flashing displays like synchronized dancing lights or a Christmas tree&apos;s blinking lights, alternating the color, speed and direction of light flashes. This is likely used to dazzle and confuse predators</li></li></ul><li>Fun facts cont.<br /><ul><li>An interesting phenomenon in this squid is the metamorphosis of the size, shape, and position of the fins as the squid grows. When the mantle is 15-25 external link mm in length, a second pair of fins begins to develop in front of the first pair. When the new pair reaches maturity, the original pair is reabsorbed. The new fins change the le om jepropulsion to fin propulsiont frvampiresty squid&apos;s swimming squid&apos;s swimming style from jet propulsion to fin propulsion
  • 39. Its Latin name translates as &quot;vampire squid from hell&quot;</li></ul>Video<br /><br />
