Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335).
Environment / Climate / Range
Ecology
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 805 m (Ref. 13608), usually 450 - 500 m (Ref. 4775). Subtropical, preferred ?; 51°N - 40°S
Eastern Atlantic: Canary Islands (Ref. 6808), 20°N (inshore from 29°N) to about 10°S west of 0°, with disjunct distribution between 14°N and 8°N, but to 23°S east of 0°. Isolates north to off south-west Ireland (Ref. 4775). Western Atlantic: tropical areas but with expatriate extensions to 51°N and 45°S in western boundary currents [(apparently absent over a minimum region off Brazil) according to Ref. 4479 or 4775] (Ref. 4479, 4775). Very rare or absent in the Indo-Pacific.
Tropical Indian and Atlantic; east coast of South America (Ref. 47377).
Length at first maturity / Size / Weight / Age
Maturity: Lm 5.2 range ? - ? cm
Max length : 8.7 cm SL male/unsexed; (Ref. 4479); max. reported age: 1 years (Ref. 4882)
High-oceanic and mesopelagic populations are found between 225-750 m during the day (maximum abundance at 450-500 m) and is nyctoepipelagic at surface down to 125 m at night (Ref. 4479). Pseudoceanic and pelagic populations are found in the upper 50 m at night (Ref. 4066). Feeding is acyclic in northwest Africa (Ref. 9198).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00363 - 0.01445), b=3.00 (2.81 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic Level (Ref.
69278): 3.0 ±0.00 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (K=1.83-3.81; tm=0.7; tmax=1.2).
Vulnerability (Ref.
