For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
This essentially tropical species does not seem to go past the 40st degree latitude north or south.
Its presence in the eastern Bering Sea is surprising.
After Regner (1985, p.42) this species is widely distributed. Its quantities were highest of all the species of Corycaeus genus determined in middle Adriatic Sea (Dalmatian coast) during 1970 to 1974. Its fequency increased going towards the open sea during the warmer part of the year.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 2 corresponding to small ambush feeding carnivorous.
