Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 0 - 840 m (Ref. 58018). Deep-water; 30°S - 52°S
Circumglobal between Subtropical Convergence and about 50°S, but extends in eastern boundary currents. South Atlantic, Pacific and parts of Indian Ocean (Ref. 47377).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - ? cm
Max length : 8.4 cm SL male/unsexed; (Ref. 5182)
Oceanic and mesopelagic, occurs mainly below 250 m at night (Ref. 4066). Taken as prey by hakes, kingklip and Cape horse mackerel (Ref. 36731). Specimens reach sexual maturity at a length of 5,4 cm; occurs in waters between 5° and 15°C. (Ref. 47377). Minimum depth from Ref. 58018.
