The adult habitat of each species was classified
by the following criteria: 1, for surface pelagic (0–50 m);
2, for midwater pelagic (50–200 m); 3, for deep water
pelagic (>200 m); 4, for near shore benthic (including
continental shelf species) and 5, for deep water benthic
(occurring in deep gullies and the continental slope).
