Grimpoteuthis wuelkeri is a medium-sized octopus characterized from multiple specimens.

Description and habitat

This octopus is known from the continental slope in the northern Atlantic Ocean at 2,055 meters deep.[4] It is likely demersal.[2]

At maximum, its body is 400 millimeters long, and its mantle is 115 millimeters long. Its fin span is around 70% of the octopus' total length. The shell is shaped like a letter "U".[1]

Its arms have around 60 to 70 suckers each,[4] and these suckers aren't sexually dimorphic.[1] A web covers about 2/3 of its arms.[4] It has a robust shell, with a thick basal portion, and strong attachments from their fins. [5]
