Opisthoteuthis agassizii is a lesser-known, deep-sea octopus first described in 1883.[5]
Like all cirrate octopuses, O. agassizii has fleshy fins to aid in swimming and a small internal shell. Males are bigger than females, and their suckers are proportionally larger. Both sexes are small. The largest specimen, a male, had a mantle (the body not including the octopus' arms) reaching 63 mm, a little under two and a half inches.[5]
Since their discovery in 1883, at least 68 specimens have been found in various parts of the Atlantic Ocean, usually near coasts.[1] They live at a maximum depth of 1,935 meters below sea level and a minimum depth of 227 meters. Like other opisthoteuthids, they occupy the benthic zone, living on or near the seafloor.[2]
