Etymology: Opisthoproctus: Greek, opisthe = behind + Greek,proktos = anus (Ref. 45335). More on author: Vaillant.
Environment: milieu / climate zone / depth range / distribution range
Ecologie
; marien bathypelagisch; diepteverspreiding 300 - 800 m (Ref. 6542), usually 500 - 700 m (Ref. 6542). Deep-water; 51°N -
Circumglobal in tropical to temperate waters. Eastern Atlantic: western Ireland to Mauritania and from Sierra Leone to Angola (Ref. 6542). South China Sea (Ref.74511)
Length at first maturity / Size / Gewicht / Leeftijd
Maturity: Lm ?, range 1 - ? cm
Max length : 10.5 cm SL mannelijk/geslacht niet bekend; (Ref. 6542)
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 11-13; Anale stekels 0. Sides of body dark; head below and behind eye sprinkled with large melanophores; snout translucent ventrally, transparent dorsally (Ref. 6597). Anal fin either with 2-3 rudimentary rays or not visible externally (Ref. 6597).
Mesopelagic (Ref. 58302). Probably not exhibiting vertical migration (Ref. 6686). The limits of its distribution coincide with the 400m-isotherm for 8°C (Ref. 6542).
