Biology     Glossary (e.g. epibenthic)

Inhabits the continental shelf (Ref. 106838). Found near the bottom. Undergoes horizontal ontogenetic migrations wherein juveniles move from spawning grounds in shallow, inshore waters at depths of 20 to 50 m, to offshore feeding grounds near the shelf edge at depths of 200 to 350 m. It then migrates back to inshore waters to spawn (Ref. 106901).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | 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.
