Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335); similis: From its similarity to D. trachops and to a lesser degree, to D. suborbitalis (Ref. 7454).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 0 - 631 m (Ref. 7454). Deep-water; 10°N - 4°N

Morphology | Morphometrics
soft rays: 15 - 16;
Vertebrae: 34 - 36. Small patches (scales) of luminous tissue at certain photophores (although subject to erosion, these luminous scales are quite persistent and are evident on specimens that have lost all body scales and most scale pockets).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00256 - 0.01178), b=3.07 (2.88 - 3.26), 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. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (30 of 100) .
