This subfamily, as currently recognized, contains only the genus Illex. These are commercially important species found in neritic waters of the North and South Atlantic (Roper et al., 1998). The number of species in the North Atlantic has been controversial, with the validity of I. oxygonius repeatedly questioned. Carlini et al. (2006) used molecular methods to confirm that three species are present in the North Atlantic, although morphological identification of specimens other than mature males can be quite difficult.
Ommastrephids with ...
suckers in eight series on tentacular club dactylus.
Found only in the Atlantic Ocean. Western Atlantic Ocean from Equator to Iceland and from southern Brazil to Patagonia, and eastern Atlantic from 20°S to 60°N, including Mediterranean Sea. These species are generally confined to continental shelf and slope areas, or nearby oceanic waters, perhaps because of their habit of sitting on the bottom at depths of up to 1000 m.
