</ref> is a genus of [[pelagic]] [[Cirrina|cirrate (finned) octopods]] known as the '''dumbo octopus'''.<ref name=MarineBio-558/> 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 (mollusc)|mantle]] above each eye. There are 17&nbsp;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.<ref name="Zglr-Sgrny-2021"/>
Prey include [[crustaceans]], [[bivalves]], worms and [[copepods]].<ref name="MarineBio-558">{{Cite web |title=Finned deep-sea octopuses |url=http://marinebio.org/species.asp?id=558 |access-date=8 May 2014 |website=MarineBio.org}}</ref> The average life span of various ''Grimpoteuthis'' species is 3 to 5&nbsp;years.<ref>{{Cite web |last=Roberts |first=Emily |date=October 8, 2018 |title=A Deep Dive with the Dumbo Octopus - Ocean Conservancy |url=https://oceanconservancy.org/blog/2018/10/08/everything-need-know-dumbo-octopus/#:~:text=The%20average%20life%20expectancy%20of%20the%20dumbo%20octopus%20is%20three%20to%20five%20years. |access-date=November 8, 2024}}</ref><ref>{{Cite web |last=Fazal |first=Rehman |date=29 September 2024 |title=A Deep Dive with the Dumbo Octopus,All About Dumbo Octopus |url=https://oceanfauna.net/dumbo-octopus/ |access-date=29 September 2024 |website=Ocean Fauna}}{{dead link|date=November 2024}}</ref>
