And their soft bodies can squeeze into impossibly small cracks and crevices where predators can't follow. Evasive BehaviorДЇast swimmers, they can jet forward by expelling water through their mantles.

The ink even contains a substance that dulls a predator's sense of smell, making the fleeing octopus harder to track. When discovered, an octopus will release a cloud of black ink to obscure its attacker's view, giving it time to swim away. Predators such as sharks, eels, and dolphins swim by without even noticing it. Using a network of pigment cells and specialized muscles in its skin, this invertebrate can almost instantaneously match the colors, patterns, and even textures of its surroundings. Its first-and most amazing-line of defense is its ability to hide in plain sight. But by far the most striking characteristic of the octopus is the wide array of techniques it uses to avoid or thwart attackers.

Members of the Grimpoteuthis species have large eyes that fill about a third the diameter of their mantle or 'head,' but their eyes have limited use in the eternal darkness of the depths. The suckers contain cirri, which are strands used to locate food and sense the environment.

The dumbo octopus has suckers on itsВ tentacles but lacks the spines found in other species used to defend against attackers. Like other octopuses, Grimpoteuthis has eight tentacles. The 'ears' may be a different color from the rest of the body.

The dumbo octopus comes in various shapes, sizes, and colors (red, white, brown, pink), plus it has the ability to 'flush' or change color to camouflage itself against the ocean floor. The average weight of the creatures is unknown. The average size of a dumbo octopus is 20 to 30 centimeters (7.9 to 12 inches) in length, but one specimen was 1.8 meters (5.9 feet) in length and weighed 5.9 kilograms (13 pounds). While the flapping fins are used for propulsion, the tentacles act as a rudder to control the swimming direction and are how the octopus crawls along the seafloor. All dumbo octopuses have the characteristic umbrella shape caused by webbing between their tentacles and all have ear-like fins they flap to propel themselves through the water. There are distinctions between the dumbo octopus species, but all are bathypelagic animals found on or near the deep ocean floor. The animals are members of the genus Grimpoteuthis, which in turn is a subset of the family Opisthoteuthidae, the umbrella octopuses.
