Abundant, with eight arms, it is a striking species because of the brilliant combination of reds, oranges, browns, greens and blues on the upper surface. This colour pattern is genetically controlled and can vary greatly between individuals living in the one rockpool. The species is omnivorous, feeding mainly on algae and detritus, but also consuming mussels and other animals swept into rockpools by wave action.
