Brief SummaryRead full entry
Members of the Ommastrephinae are the most oceanic members of the Ommastrephidae and are commonly attracted to surface night-lights in the open ocean. Some species are fished commercially and one species, Ommastrephes bartramii, was taken in the North Pacific in quantities over 350,000 tons per year during the 1980s (Bower and Ichii, 2005). This subfamily contains the largest species (Doscidicus gigas) reaching a size of 120 cm ML and the smallest species (Hyaloteuthis pelagica) reaching a size of about 9 cm ML (Nesis, 1982/87). A wide variety of luminous organs are present on the mantle, head, arms, viscera and eyes but vary with species.
