Dumbo Octopuses Grimpoteuthis are found in some of the deepest places on Earth, 1,300 feet below the surface. They get their name from their ear-like fins which they use to swim through the dark depths of the open ocean. There are at least 15 known species of Dumbo Octopus in the world.
Life at these extreme depths requires the ability to live in very cold water and in the complete absence of sunlight. These octopuses are naturally rare, and the deep sea is incredibly vast. So they’ve specialized behaviors to increase the likelihood that they can successfully reproduce anytime that they find a mate. Females always carry eggs in different stages of development, and are able to store sperm for long periods of time after mating with a male.
They are foraging predators and eat pelagic invertebrates that swim above the sea floor. Since there aren’t many large predators in the deep sea, dumbo octopuses’ primary predators are diving fishes and marine mammals, including tunas, sharks, and dolphins.They are only very rarely captured in fishing nets and are probably not threatened by human activities.
