Grimpoteuthis

Grimpoteuthis is a genus of pelagic cirrate (finned) octopods known as the dumbo octopus. The name "dumbo" originates from their resemblance to the title character of Disney's 1941 film Dumbo, having two prominent ear-like fins which extend from the mantle above each eye. There are 17 species recognized in the genus. The Dumbo octopus has a gelatinous body and uses fin propulsion for movement, which also helps it to conserve energy in its extreme deep-sea environment. These unique physical traits distinguish it from other octopuses, which primarily rely on jet propulsion. Prey include crustaceans, bivalves, worms and copepods. The lifespan of Grimpoteuthis species unknown, but is likely to be several years based on estimates from other cirrate octopods.
