The Vampire Squid files....

The vampire squid (Vampyroteuthis infernalis) lives in the deep ocean, home to the largest ecosystems on our planet. A "living fossil," this animal has remained relatively unchanged for hundreds of millions of years. The deep ocean contains what may be the greatest number of animal species, the greatest biomass, and the greatest number of individual organisms in the living world. Humans have explored the deep ocean for about 150 years, and most of what is known is based on studies of the deep seafloor. In contrast, the water column above the deep seabed comprises more than 90% of the living space, yet less than 1% of this biome has been explored. The deep pelagic biota is the largest and least-known major faunal group on Earth despite its obvious importance at the global scale. Pelagic species represent an incomparable reservoir of biodiversity. Although we have yet to discover and describe the majority of these species, the threats to their continued existence are numerous and growing.
