Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335). More on authors: Goode & Bean.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; oceanodromous (Ref. 51243); depth range 0 - 2999 m (Ref. 58018), usually 200 - ? m (Ref. 4479). Deep-water; 36°N - 49°S, 78°W - 180°E
Eastern Atlantic: disjunct distribution from Morocco-Angola (gap in 17°N-11°N). Western Atlantic: USA to Brazil with isolated specimens to Argentina. Indian Ocean: equatorial waters and west of 70°E to 36°S in Agulhas Current. Indo-west-central Pacific: Southeast Asian seas and north to 8°N and eastwards to 126°W (Ref. 4775). South China Sea (Ref.74511).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 9 - 10 cm
Max length : 11.8 cm SL male/unsexed; (Ref. 4479)
Oceanic and mesopelagic, found between 425-750 m during the day and between 40-550 m at night (most abundant below 200 m at night) (Ref. 4066, 4775). There is size stratification with depth both day and night (Ref. 4775).

Estimates based on models
Preferred temperature (Ref. 115969
): 4 - 15.7, mean 7.6 °C (based on 2177 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00247 - 0.01279), b=3.09 (2.90 - 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
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
