Join this group to download.
Description: The octopuses of the genus Grimpoteuthis are also known as Dumbo octopuses from the ear-like fins protruding from the top of their head-like bodies, resembling the ears of Walt Disneys flying elephant Dumbo. They are bathyal creatures, living at extreme depths of 3,000 - 4,000 metres (9,800 - 13,000 ft), with some living up to 7,000 m (23,000 ft) below sea level, which is the deepest of any known octopus. They are some of the rarest of the Octopoda species. They can flush the transparent layer of their skin at will & are pelagic animals, as with all other cirrate octopuses. The largest Dumbo octopus ever recorded was 6 ft (1.8 m) in length & weighed 13 lb (5.9 kg), although the normal size for the various species is thought to be smaller. They hover above the sea floor, searching for polychaetes, pelagic copepods, isopods, amphipods & other crustaceans for food. The Dumbo octopus is strange in the way it consumes food in that it swa11ows its prey whole, which differs from any other kind of octopus. They move by pulsing their arms, shooting water through their funnel, by waving their ear-like fins, or any combination thereof. Males & females differ in their size & s*cker patterns.
