It has the common name algae octopus due to its typical resting camouflage, which resembles a gastropod shell overgrown with algae. It is small in size with a mantle around the size of a small orange ( c. 7 cm or 3 inches) and arms 25 cm (10 inches) in length, and is adept at mimicking its surroundings.

In doing so, it uses a jet mechanism that involves creating a much higher pressure in its mantle cavity that allows it to propel itself through the water. [20] As the common octopus' heart and gills are located within its mantle, this high pressure also constricts and puts constraints on the various vessels that are returning blood to the heart ...
In comparison, many shallow water octopuses only live for a year. [ 2 ] [ 3 ] Higher water temperatures result in increased growth rates, but shorter life spans in Bathypolypus arcticus . [ 3 ] Temperatures above 10 °C (50 °F) are typically lethal to this cold-water species, although specimens have survived at 11 °C (52 °F) if slowly ...
