Maximum depth from Ref. 110525. Depth range from 200 to 1,000 m. These small pelagic octopuses typically occur over deeper water as adults. Young animals tend to occur in the shallower end of the range. As members of this species reach sexual maturity the iridescence of the digestive gland and eyes is lost, and animals migrate to deeper darker waters in the later stages of the life cycle. Nearly mature males have salivary glands that are much larger than those of comparable females. Salivary products may be used as chemical attractant for females. The female light organ may be used for reproductive signalling to males (Ref. 96968).
Life cycle and mating behavior
Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Eggs | Sự sinh sản | Larvae
Members of the class Cephalopoda are gonochoric. Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the female's mantle cavity where fertilization usually occurs. Life cycle: Embryos hatch into planktonic stage and live for some time before they grow larger and take up a benthic existence as adults.
