These filaments can be extended up to at least twice whole body length. Two pouches containing the tactile filaments are concealed within the webbing between the first and second pairs of arms. Beaks, located in the center of the circle of arms, are white. Mature adults have a pair of small fins projecting from sides of body furthest from eyes. The eyes are large and globular and colored red or blue depending on lighting. The distal portion of each arm has suckers. It has eight arms that are connected by webbing and each is lined with rows of fleshy cirri (spine-like projections). Vampire squid have a gelatinous body colored jet black to pale reddish, depending on location and light conditions. They also have low metabolisms and use very little energy. To cope with this they use hemocyanin (copper-based blue blood) that binds oxygen very well, and they have a large gill surface area to absorb oxygen. Most cephalopods cannot go below 50 percent oxygen saturation. This is the OML (oxygen minimal layer) where there may be less than 5 percent oxygen saturation and little or no light. The water temperature at those depths is very cold, 2-6o C (35.6 to 42.8 o F). Vampire squid are found in temperate and tropical deep-water zones worldwide at depths of 600 to 1200 m (1958 to 3937 ft). Tropical to temperate deep seas globally, within latitudes 40 degrees north and 40 degrees south of the equator Habitat
CLIMATE CHANGE: Uncertain At the AquariumĪlthough not on exhibit in the Aquarium, the vampire squid is included in our website animal database to expand on the information originally presented in the Wonders of the Deep gallery, which was open from 2013 to 2016.
