Found in sandy and muddy substrate along coasts, in depths between 27 and 376 m, often in areas colonized by the seagrass, Posidonia oceanica. A benthic, gregarious species; able to leave the bottom and undergo significant vertical migrations. Spawning may commence as early as spring and through autumn in the Mediterranean. In aquaria, females were observed to spawn intermittently over a 2-week period and then died. Frequently captured as a bycatch of trawl and purse seine fisheries and may be an abundant component of bobtails marketed locally (Ref. 1695).
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.
