  Bathyteuthis
The Bathyteuthis species occupy the lower mesopelagic to bathypelagic depth zones, and they are scattered throughout the world’s oceans.
Bathyteuthis was erected as a new genus by Hoyle (1885a) for a new species of deep sea squid (B.
Hoyle (1885b) immediately recognized that Benthoteuthis was a synonym of Bathyteuthis (which had publication priority by 2 months), and he mentioned in 1886 the possibility that the two species might be conspecific.

 Bathyteuthoida
Buccal connectives attach to the ventral borders of Arms IV in the Chtenopterygidae and to the dorsal borders in the Bathyteuthididae.
The two genera that represent these families (Bathyteuthis, Cthenopteryx) were, at one time, placed within the same family (e.g., Naef, 1921) because they share a number of similar features.
They especially show strong similarities in the structure of the tentacular clubs, the sucker arrangement on the arms and the morphology of their gladii.

 Bathyteuthis berryi
The holotype is housed at the Santa Barbara Museum of Natural History, California.
Several specimens of Bathyteuthis were discovered during a study of the deep pelagic cephalopods off the coast of Southern California (see Young, 1972).
They were determined to be a new species based especially on the extremely large number of suckers on arms I-III and the proportionally longer, attenuate arms (Roper, 1968).
