Grimpoteuthis pacifica is an octopus known from one badly damaged specimen. It is not completely described, and it is not easily separated from some other species of octopus. Nothing clearly differentiates G. pacifica from Grimpoteuthis hippocrepium except for its type locality.[1]
The specimen was captured off Papua New Guinea in the South Pacific Ocean in 1885, more specifically in the Coral Sea, where it was 4500m (14,800feet) below sea level. Grimpoteuthis pacifica is probably demersal.
Its fins are 55mm long.[2] Each arm has 52 suckers, the largest of which are 2.5mm across. Its arms range in length from 130mm170mm long, and its eyes are very large.
The octopus is a deep purple color, though some parts are paler.
