The dumbo octopus (Grimpoteuthis) is a bit different than most cephalopods. This genus of pelagic umbrella octopuses do not have an ink sac. Instead, they use their chromatophore cells to change colors, which helps them avoid predators while living in the cold, abyssal depths ranging from 3,000 to 23,000 feet. 👻 🐙 | Science Channel

Dumbo octopuses are rarely seen as they live in the deep open ocean, reaching down to depths of at least 13,100 feet and perhaps much deeper. This makes them the deepest living of all known octopuses! 🐙 Footage via Nautilus Live | Oceana

Deep-sea explorers have captured rare footage of a “Dumbo octopus” swimming nearly 10,000 feet below the surface of the Atlantic Ocean. Named for its ear-like fins, this elusive creature lives in one of the most extreme environments on Earth—total darkness, crushing pressure, and near-freezing temperatures. Dumbo octopuses use their fins to gracefully “fly” through the water rather than jet propulsion. Because of their extreme depth range, sightings are uncommon and rely on advanced submersible
