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; non-migratory; depth range 0 - 6000 m (Ref. 58018). Deep-water; 50°N - 49°S, 82°W - 180°W
Eastern Atlantic: from 40° to 17°N, from 19°S to Subtropical Convergence zone. Western Atlantic: USA to about 20°N, from Brazil to Subtropical Convergence. Indian Ocean: west of 70°E between 5°S-38°S. Western Pacific: between 0° and 29°N, Southeast Asian seas, New South Wales, Australia (Ref. 7300) and New Zealand (Ref. 5755). Central and Southeast Pacific.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 4066)
High-oceanic and mesopelagic species (Ref. 4066), found between 501-700 m during the day and between 40-175 m during the night, exhibiting size stratification with depth (Ref. 4479). Probably spawns in deep water during spring (Ref. 4479).

Estimates based on models
Preferred temperature (Ref. 115969
): 2 - 5.8, mean 3.2 °C (based on 3796 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00396 - 0.02303), b=3.02 (2.81 - 3.23), 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 (40 of 100) .
