Description
Grimpoteuthis bathynectes in general form is distinguished from other Grimpoteuthis species by a suite of characteristics. Each of the dorsal arms have 47–58 suckers, with the suckers slightly larger and more globular in males. The pairs of cirri start between the third and fourth sucker, and at greatest length the cirri are roughly equal to the sucker diameter.The internal shell is roughly U-shaped, its ends flattened with small spikes. The octopus lacks a radula and posterior salivary gland, and has seven to nine gill lamellae on each gill. The mantle and head are gray, posterior edges of the fins are reddish brown the inside of the arm webbing is dark purple to reddish brown.
The diet and behavior of G. bathynectes has not been recorded, but is presumably similar to others in its genus.
