Teleostei (teleosts) > Myctophiformes (Lanternfishes) > Myctophidae (Lanternfishes) > Diaphinae
Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335); trachops: From the uneven surface of the lower orbital margin ['trachops' = rough; ''ops' = eye].

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathypelagic; depth range 100 - 686 m (Ref. 7454). Deep-water

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 14; Anal soft rays: 14 - 16; Vertebrae: 34 - 35. Surface of lower orbital margin uneven, caused by the small domed intrusions of pigmented tissue covering the minute, probably luminous, dots anterior to Vn

Meso- and benthopelagic at 95-225 m at night, 425-600 m during day (Ref. 58302).

Estimates based on models

Preferred temperature (Ref. 123201): 10.1 - 15.2, mean 12.1 °C (based on 11 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00328 - 0.01756), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.16 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
