Etymology: Diaphus: Greek, dis, dia = through + Greek, physa, phyo = to beget, to have as offspring (Ref. 45335); theta: Named after the Greek letter and refers to the body photophores which are divided horizontally by a fine line of black pigment (Ref. 6885). More on author: Eigenmann, Eigenmann.

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-14; Anal spines: 0; Anal soft rays: 12 - 14; Vertebrae: 34 - 36. Adipose small, narrow based, slender (Ref. 6885). Brown to black on dorsal surface, lighter ventrally; fins pale (Ref. 6885). Branchiostegal rays: 9 (Ref. 31442).

Epipelagic to mesopelagic (Ref. 31442). Feed at night or in the morning (Ref. 9199), on euphausiids, copepods, and amphipods (Ref. 11712). Oviparous, with planktonic eggs and larvae (Ref. 31442). Lipid content is 15.8 % in fresh body weight while wax ester is present in trace amounts (Ref. 9197). Minimum depth reported from Ref. 28981.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00401 - 0.02170), b=3.03 (2.82 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.1 se; Based on diet studies.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (31 of 100) .
