![]() ![]() Since dumbo octopuses live so deep, they are not threatened much by human activity. I guess you could call that one a jumbo dumbo octopus. ![]() The largest of these was 5 feet 10 inches (1.8 m) long and weighed 13 pounds (5.9 kg). They do this by expanding and contracting their tentacles, making use of the funnel-like webbing between their tentacles.ĭumbo octopuses are fairly small, averaging about 8 to 12 inches (20-30 cm) long, about the size of a guinea pig. Since these methods of movement are slow, to escape from predators they also can dart away by aggressively squeezing water out. They can also crawl along the sea floor with their tentacles (you can call them arms if you want, but I just like to say the word tentacles). This makes them by far the deepest living of all the octopuses.ĭumbo octopuses appear to move through the water by slowly flapping their ear-like fins, but actually they are gently squirting water from their tentacle-funnel, and their ear fins are providing stability and steering. That's over four miles down! Chances are, they live even deeper than that. Most of them live at depths of about 13,000 feet (4,000 m), and some have been found as deep as 23,000 feet (7,000 m). Why? Because these octopuses live deep in the ocean. You're not going to see a dumbo octopus while you're out snorkeling in shallow water. Actually, very little is known about the dumbo octopus, but we know enough to be confident that they are awesome! Let's take a look. The name dumbo comes from the fact that they have two fins that spread out above the eyes, resembling the oversized ears of Dumbo the elephant (from the 1941 animated Disney film). Dumbo octopuses include about 13 species of umbrella octopuses (a group that kind of look like an umbrella when they spread their tentacles).
