Grimpoteuthis plena is known from only one specimen, which cannot be easily separated from other species of Grimpoteuthis in the Atlantic Ocean.[3] The specimen was in poor condition. It's similar to Grimpoteuthis wuelkeri,[4] and may be a junior specimen of Grimpoteuthis umbellata.[1]

Description and habitat

G. plena was found in the northwestern Atlantic Ocean, at 1,963 meters deep.[4][5] Like other members of Grimpoteuthidae, it could be demersal.[1]

The specimen's mantle reached 57 millimeters long, and its total length reached 185 millimeters.[5]

Some of its arms are longer than the others. There are between 55 and 60 suckers per arm, the largest of which are 2.5 millimeters in diameter. The octopus' cirri are short. Its fins are each 32 millimeters long. The eyes are small: each is 12 millimeters in diameter. [3]
