Linophrynidae (Leftvents)
Etymology: Haplophryne: Greek, 'haplos' = single or simple + Greek, 'phryne' = toad (meaning "simple toad") (Ref. 86949).
Environment: milieu / climate zone / نطاق العمق / distribution range
البيئة

الحجم / وزن / العمر
النضج: Lm ? range ? - ? cm
Max length : 15.9 cm SL ذكر/ مختلط الجنس; (Ref. 58502); common length : 8.0 cm SL ذكر/ مختلط الجنس; (Ref. 1468); common length :5 cm (female)
الأشواك الظهرية (المجموع) : 0; الأشعة الظهرية الناعمة (المجموع) : 3; شوكة شرجية: 0; أشعه شرجية لينه: 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).
Body shape (shape guide): short and / or deep; Cross section: circular.
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.
