Bathyteuthis abyssicolaClyde F. E. Roper
- Protective membranes low, fleshy, without free trabeculae.
- Arms short, not attenuate; tips blunt.
- Arm suckers relatively few in number, about 100 on each of arms I-III.
- Arm sucker rings with 8-18 separated, bluntly rounded to truncate protuberances.
- Tentacles and clubs relatively short.
- Gills short, narrow.
Vertical DistributionThis bathypelagic species normally occurs at 700-2000 m, but records are given as 100-4200 m; the greater depths probably are artifacts from open (non-closing) sampling nets. Paralarvae and juveniles live at shallower depths than adults. In the Southern Ocean (Antarctic Ocean), the population undertakes a deep diel vertical migration (Roper, 1969). The population in the eastern tropical-subtropical North Atlantic also demonstrates a diel vertical migration (Clarke & Lu, 1975; Lu & Clarke, 1975).
Geographical DistributionBathyteuthis abyssicola is cosmopolitan in the world oceans. It is circumpolar in the Southern Ocean and in the highly productive waters of the eastern Pacific, the Atlantic, and the Indian Oceans (Roper, 1969).
