Also mesopelagic (Ref. 7300). A small deep-sea angler fish. Males dwarfed, becoming parasitic on females (Ref. 10762). An 8 cm female was found with 3 parasitic males of 18 mm length, attached to her ventral side. Adult (=parasitic) males are colorless with reduced teeth, jaws, and eyes. Information on the maximum length of female was taken from Ref. 10762.
