Σχόλια Males are fully mature at 10.5 cm mantle length; females clearly developing but immature at 8.5 cm mantle length, with paired nidamental glands. Depths of capture in open nets range from 300 to 500 m at night (1 at 3,500 m) and 800 to 2,500 m during daytime: this clearly is a meso- to bathypelagic species. Specimens are reported as prey of lancetfish, blue shark and sperm whale (Ref. 97142).
