Dumbo Octopus. Grimpoteuthis spp. Worldwide in tropical to temperate latitudes. Deep open ocean bathypelagic. Foraging predator. Class Cephalopoda squids, octopuses, and relatives , Family Opisthoteuthidae umbrella octopuses.
There are at least 15 species of dumbo octopuses, and like all umbrella octopuses, their arms are connected by a web of skin, causing them to resemble umbrellas when their arms are spread apart.
Dumbo octopuses live in the deep open ocean down to depths of at least 13, feet m and perhaps much deeper, making this group the deepest living of all known octopuses.
Life at these extreme depths requires the ability to live in very cold water and in the complete absence of sunlight. Dumbo octopuses are naturally rare, and the deep sea is enormous, so these species have specialized behaviors to increase the likelihood that they can successfully reproduce anytime that they find a mate.

They live on the seafloor or hover just slightly above it at depths of depths of to m to ft , The similarity of the ear-like fins protruding from the top of the mantle of the Dumbo octopus to the ears of the Disney character, Dumbo, the Flying elephant, led to the common name, dumbo.
Grimpoteuthis spp. Size Most species are cm 7. Reproduction Grimpoteuthis has one of the most unusual breeding capabilities of any marine life. Behavior Neutrally buoyant, they have several observed types of mobility. Animal can use each of these techniques separately or swim by combining all of them.
Fastest swimming is associated with quick release of water from the funnel. This technique is used when dumbo octopus needs to escape from the predators. Since dumbo octopus spends most of its life on the great depths, it does not have a lot of predators. Main predators of dumbo octopi are sharks and killer whales. Dumbo octopus eat different type of crustaceans, bivalve, worms on the sea bottom and copepods that are part of the zoo-plankton when they swim near the surface of the water.
Dumbo octopus swallows the prey whole. For that reason, size of the prey never exceeds mm. Dumbo octopus does not have mating season.
Female is able to deposit eggs throughout the whole year. One arm of males has a large segment that is used to deliver packages of sperm into female's body. Eggs are fertilized inside the female's body.
