Grimpoteuthis angularis (Verhoeff & O'Shea, 2022)

Grimpoteuthis angularis is a species of octopus in the family Grimpoteuthidae. ^{[1] [2]} It was first described by Tristan J Verhoeff and Steve O'Shea in 2022, based on a single specimen found in New Zealand. ^[3]

Taxonomy

The species was given the name angularis, referring to the octopus' angled shell. ^[3] Verhoeff & O'Shea proposed that the common name of the species should be angle-shelled dumbo octopus. ^[3] This species (as well as other Grimpoteuthis) may belong in its own family, the Grimpoteuthididae. ^[3]

Description and habitat

The shell of Grimpoteuthis angularis is V-shaped, notably different to other Grimpoteuthis; the relatively elongate cirri are also distinctive. ^[3] The holotype was discovered on the Chatham Rise to the east of New Zealand, at a depth of 628 metres. ^[3]
