Opisthoproctidae

(Barreleyes or spookfishes)

Etymology: Opisthoproctus: Greek, opisthe = behind + Greek,proktos = anus (Ref. 45335).  More on author: Vaillant.

Marine; bathypelagic; depth range 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)

Maturity: Lm&nbsp?, range 1 – ? cm
Max length : 10.5 cm SL male/unsexed; (Ref. 6542)

Dorsal
spines
(total): 0;
Dorsal
soft rays
(total): 11-13;
Anal
spines: 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).
