Ecology of Argonauta nouryi
Main Ref. Hochberg, F.G. and Y.E. Camacho-García, 2009
Remarks 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).
