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 40 - 777 m (Ref. 56504). Deep-water; 50°N -
Eastern Atlantic: Bay of Biscay including the Mediterranean to Liberia (uncommon between Morocco to Mauritania). Elsewhere in the Atlantic Ocean, south and east of 50°N and 45°W to 35°N, but east of 35°W to about 20°N. Indian Ocean: two specimens at 29°30'S, 64°56'E.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 5 - ? cm
Max length : 7.0 cm SL male/unsexed; (Ref. 4479)
High-oceanic, found between 225-650 m during the day and between 40-275 m at night exhibiting size stratification with depth and with adult females below 450 m (Ref. 4479). Depth range from 300-777 m in the eastern Ionian Sea (Ref. 56504). Large juveniles, sub-adults and adults from the Mediterranean are known to be migratory (Ref. 4775).

Estimates based on models
Preferred temperature (Ref. 115969
): 10.2 - 16.5, mean 14.1 °C (based on 226 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00403 - 0.02161), b=3.03 (2.82 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
