The mouth of the squid is equipped with a sharp horny beak made of chitin, used to kill and tear prey into manageable pieces.
The majority of squid are no more than 60 cm in length, but the giant squid is reportedly up to 20 m in length, which made it the largest invertebrate in the world, and it has the largest eyes of all.
The squid now resides in a glass tank, filled to the brim with preservative solution, and is one of 22 million specimens that can be seen as part of the behind-the-scenes Darwin Centre tour of the Natural History Museum in London.

 Vampyroteuthis infernalis, Vampire Squid at MarineBio.org
The Vampire squid, Vampyroteuthis infernalis (Chun, 1903), which translates to "vampire squid from Hell", is the only known member of the Order Vampyromorphida, the seventh order in the Class Cephalopoda and combines features from both octopodiformes and decapodiformes suggesting it may represent an ancestral line between the two groups (Robison et al.
The Vampire squid is adapted to live in a deep sea environment with photophores, large circular organs found on the posterior end of each fin and distributed on the mantle, funnel, head, and aboral surface, that produce luminescent clouds of glowing particles that last between 2-9 minutes.
The Vampire squid is found in the temperate and tropical regions of the ocean.

 Vampyroteuthis   (Site not responding. Last check: 2007-10-19)
Vampyroteuthis infernalis, the vampire squid from hell, is a cephalopod that lives in the oxygen minimum layer (600 - 800 m depth) throughout the world's temperate and tropical oceans.
The vampire squid has much in common with both squids and octopuses but it was placed in its own Order, the Vampyromorpha, based on the presence of sensory filaments.
The metamorphosis confused early cephalopod researchers who described several "species" of vampire squid until Grace Pickford (1936; 1949; 1952) was able to determine that the two-finned 'species' was actually a juvenile stage of the one-finned 'species'.

Additionally, though no adult giant squid has ever been seen live, it is believed to be a passive predator, suspended motionless in the water column at a 45° angle above its locked-together, vertically depending tentacles, waiting for fish or other small squid to swim within reach.
Vampire squid also swim primarily using their lateral fins; throughout the lifespan ontogeny of the animal, however, the fins change size and position, modifying the gait for greater efficiency as the animal's surface area to volume ratio decreases with growth (Seibel et al.

 Vampyroteuthis infernalis
The vampire squid is rather small, reaching a maximum of 13 cm ML (Nesis, 1982/7) and is very gelatinous; its consistency is that of a jellyfish.
The latter authors suggest that flashing of the arm-tip organs is controlled by covering or exposing the photogenic region by the pigmented sides of the arm tips, that the microscopic glowing particles are not luminescent bacteria and that the function of the bioluminescence is to startle or distract a predator.
ROV observations in Monterey Bay, California suggest that the vampire is restricted to the oxygen minimum layer in this bay at an average depth of 690m and oxygen levels of 0.22 ml/l Hunt, 1996.

With the exception of her monographs on the squid’s life span, in which she coined the term “mayfly squid,” Johnson’s work is today considered primarily of historical importance.
If this is the case, then the mayfly squid may have entered the Florida ecosystem when someone grew bored with their exotic acquisition and dumped a tank of adult and/or juvenile squid into a lake or stream.

(i.e., octopi, squid, etc.) have complex image-forming eyes that are comparative to a human's; focusing is done, however, by moving the lens in and out rather than by changing its shape as in the human eye.
