Max length : 15.9 cm SL جنس نر / بدون خواص جنسي; (Ref. 58502); common length : 8.0 cm SL جنس نر / بدون خواص جنسي; (Ref. 1468); common length :5 cm (female)
خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 3; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 3. Mature females are unpigmented and have a nearly rounded shape of body. There are spines above the eyes and behind the mouth. The illicium consists of a rounded flap without pole. Small numerous teeth in both jaws (Ref. 557). Free lining males are characterized by: having weak sphenotic spines, nearly absent; slender and angled preopercle; moderately elevated epiotic region of skull; well developed premaxillae; 20-24 teeth on each side of upper and lower jaws (Ref. 86949).
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.
