Etymology: Benthalbella: A possible interpretation is related to Greek, benthos = the deep sea + Latin, albus = white; but it is need more information.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; bathypelagic; depth range 10 - 2294 m (Ref. 44036). Deep-water
North Pacific. South China Sea (Ref.74511).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.8 cm SL male/unsexed; (Ref. 28981)
Usually live 305 m or more below the surface but move upward in the water at night, sometimes to relatively shallow depths. Are believed to be rapid swimmers, skillful at avoiding nets, which would account for the scarcity of large adults in research collections. Juveniles feed heavily on crustaceans, while adults feed mainly on fish (Ref. 4525).
