Length at first maturity / Μέγεθος / Weight / Age

Γεννητική Ωρίμανση: L_m ? range ? - ? cm Max length : 17.4 cm TL (female)

Pelagic. Mating behavior unknown. On contact with the female, presumably the male autotomizes the hectocotylus. Multiple hectocotyli can persist in the mantle cavities of females for extended periods. Eggs of up to three different developmental stages may be present within a single shell. Large numbers of females have been observed at the surface in open-ocean during daylight hours. Females may attach to each other, forming large chains of up to 18 individuals. Females are known to strand on beaches in the southern Gulf of California, Mexico, during late winter and early spring (January to March) (Ref 96968) (Ref. 83938).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
