Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335). More on author: Norman.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 40 - 475 m (Ref. 4479). Deep-water; 42°N - 27°S
Eastern Atlantic: Mauritanian Upwelling region and Gulf of Guinea south to 23°S. Western Atlantic: USA (Gulf Stream) to Gulf of Mexico and the Caribbean Sea. Northwest Atlantic: Canada (Ref. 5951). Reported off the Guianas (Ref. 13608).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - 4 cm
Max length : 7.0 cm SL male/unsexed; (Ref. 4479)
Pseudoceanic, found over continental shelves and slopes (Ref. 4066). Occurs between 325-475 m during the day; between 40-250 m at night (maximum abundance in 100 m depth). Mesopelagic (Ref. 5951). In the Cariaco Trench, day distribution is at 250 m and at night at 50 m due to anoxic conditions below 400 m and free hydrogen sulphide below 375 m. Fecundity is about 1,000 eggs per female (Ref. 9504).
