Taxonomy

The species was given the name angularis, referring to the octopus' angled shell.^[2] Verhoeff & O'Shea proposed that the common name of the species should be angle-shelled dumbo octopus.^[2] This species (as well as other Grimpoteuthis) may belong in its own family, the Grimpoteuthididae.^[2]

Description and habitat

The shell of Grimpoteuthis angularis is V-shaped, notably different to other Grimpoteuthis; the relatively elongate cirri are also distinctive.^[2] The holotype was discovered on the Chatham Rise to the east of New Zealand, at a depth of 628 metres.^[2]
