Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm Max length : 20.0 cm ML maschio/sesso non determinato; (Fonte Biblio. 122435); 50 cm ML (female)
Total length to at least 11.8 cm. Shell length to 10.6 cm. Total length to at least 1.2 cm (excluding hectocotylus), and 4 cm (including hectecotylus) (Ref. 98986). Before maturation, female argonauts utilize their glands on their dorsal arms to produce a shell, which it uses as a home. Primarily feeds on jellyfish and is typically found associated with them, most likely as a camouflage. Included in their diet are pelagic mollusks, octopods, crustaceans, comb jellyfishes and fishes. Males are small and possesses a third arm which detaches during mating and carries the spermatophores to the females. They are observed to inhabit salps (Ref. 98471).
Ciclo vitale e comportamento di accoppiamento
Maturità | Riproduzione | Deposizione | Uova | Fecondità | Larve
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.
