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 ? - 250 m (Ref. 36731). Deep-water
Circumglobal distribution in the region of the Subtropical Convergence, but may be absent over the region 115°W to the coast of Chile. Eastern Atlantic: known from the southern boundary limit, 23°S to 21°S but probably farther to the north in the Benguela Upwelling Region.
Southwest Atlantic: between 32°S and 46°S (Ref. 47377).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 4 - ? cm
Max length : 5.4 cm SL male/unsexed; (Ref. 4479)
Oceanic and mesopelagic (Ref. 4066). Taken as prey by hakes, kingklip and Cape horse mackerel (Ref. 36731). Found in the upper 250 m at night. Spawns in spring-early summer.
Reach sexual maturity at a length of 3,6 cm (Ref. 47377).

Estimates based on models
Preferred temperature (Ref. 115969
): 11.8 - 18.8, mean 15.7 °C (based on 7 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00207 - 0.01160), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
