Vampire squid
Vampyroteuthis infernalis

— Where the name comes from
Vampyroteuthis infernalis means “vampire squid from hell”, and there is no way of making it less theatrical. Carl Chun named it in 1903 looking at a black specimen, the web between its arms spread like a cloak and its eyes red: it looked like a vampire in miniature. It is a name that has condemned the animal to a false reputation, because it sucks nothing and hunts nobody.

— What sets it apart
It eats the dust that falls. For a century it was believed a predator, and instead it unfurls two extremely fine filaments eight times its body length and uses them as passive lines to gather marine snow — remains of plankton, shells, droppings drifting slowly down from the surface — kneading it with mucus into small parcels. It is the only known cephalopod that hunts nothing living. It inhabits the oxygen minimum zone, a band where almost no active animal survives, and manages it with a very low metabolism, blood extraordinarily avid for oxygen, and a gelatinous body with almost no muscle.
