The octopus is a benthic species characterized by direct development, a short life cycle, and remarkable motor intelligence and visual acuity. Its coloration is highly variable, rapidly adapting to the environment, ranging from brown to green, yellow, and white. Its body exhibits a warty texture.

The octopus possesses eight tentacles of equal length, each equipped with two rows of suction cups used for capturing prey and locomotion. At the base of the tentacles lies the siphon, which enables rapid propulsion through jet propulsion.

In Mauritania, octopuses inhabit various bottom types, with a preference for fine to coarse sand sediments. They construct burrows in these soft substrates as a refuge from predators. The cephalopod itself excavates its den, venturing out only for feeding and reproduction.
