| Abstract |
A reproductive strategy consisting of deep- water spawning and egg-care was inferred for the midwater squid Gonatus onyx Young, 1972. Brooding females and associated eggs and hatchlings, captured between 1250 and 1750?m depth off southern California, are described. Brooding females appear to be senescent and lack tentacles. Large eggs of this species (3?mm) at cold temperatures (3?°C at capture depth) may require as long as 9?mo to develop. The high lipid content of the digestive gland in adult females of this species may provide fuel to support such an extended “brooding” period. |
