The Blanket Octopus. These species exhibit an extreme degree of sexual dimorphism. Females may grow to over 2 metres in length whereas the tiny males are at most a few centimeters long. The males have a specially modified third right arm which stores sperm, known as hectocotylus. During mating, this arm detaches itself and crawls into the mantle of the female to fertilize her eggs. The male dies shortly after mating. The females carry over 100,000 tiny eggs that are attached to a sausage-shaped calcareous secretion held at the base of the dorsal arms and carried by the female until hatching.
