Alien  Earthlings

Grimpoteuthis is a genus of pelagic cirrate 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 name “dumbo octopus” does not refer to one species, but rather 18 different species in the genus Grimpoteuthis. They live in the deep sea around the world, ranging from depths of 100 to 7,000 meters (328 to 22,965 feet). Their large fins that flap like ears and webbed arms help them swim through the dark water — an unusual means of travel for octopuses, which typically rely on jet propulsion to move. They also differ from many other octopuses in that dumbo octopuses do not have an ink sac and cannot change — likely since these abilities are of no use in their pitch-black habitat.

It is believed dumbo octopuses feed primarily on small, slow-moving animals such as tiny crustaceans and marine worms. They may be vulnerable to a number of predators, including sharks, fur seals, fish, and sperm whales. Most of their life, however, remains a mystery — some dumbo octopus species are known only from a single recorded observation — and scientists still have much to learn about these hard-to-study octopuses.
