Grimpoteuthis is a genus of pelagic umbrella octopus that live in the deep sea. Prominent ear-like fins protrude from the mantle just above their lateral eyes. They have a U or V shaped shell in their mantle which gives them a bell shaped appearance. Some species are short, squat and yellow, while others resemble a jellyfish with one, big, brown, walking shoe. Some have suckers, in addition to spines, on all 8 webbed tentacles while others look like a regular octopus with the addition of blue or other colored "ears". Theseoctopuses are commonly nicknamed "Dumbo octopuses" or "Dumbo octopods" in reference to how the ear-like fins protruding from the top of their head-like bodies resemble the ears of Walt Disney's flying elephant Dumbo. At the moment scientists know that there are 37 different types of the Grimpoteuthis  each having a different aspect from all the others. These features could be larger ears or different colours. As these animals live at the bottom of the sea they have a very small food supply. Prey includeCrustaceans, bivalves, worms on the ocean floor and Copepods. These octopi have a short life span. The average life span of various Grimpoteuthis species is 3 to 5 years.
