Teleostei (teleosts) > Scombriformes (Mackerels) > Chiasmodontidae (Snaketooth fishes)
Etymology: Pseudoscopelus: Greek, pseudes = false + Greek, skopelos = a lantern fish (Ref. 45335). Lütken did not recognize the presence of photophores on the body, confusing them with pores, but referred to a genus of lanternfish (Scopelus now Myctophum) when he named the genus (Ref. 85782); odontoglossus: Name from the Greek ‘odont-‘, meaning tooth, and ‘glosso’, for tongue; referring to the presence of well developed teeth on the bones of the tongue, basihyal and first ceratobranchial..

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 21 - 24; Anal soft rays: 21 - 24; Vertebrae: 37. This species of the Pseudoscopelus astronesthidens species group is distinguished within the group by a unique characteristic: teeth on basihyal and second basibranchial in 3 rows, 28-40 (vs. 2 rows, basihyal teeth 15-25). It is further distinguished from P. australis by the presence of rakers on first ceratobranchial (vs. none), palatine teeth in 2 rows, total teeth 16-26 (vs. single row, 10-16), and posteropreopercular photophores present (vs. absent), and precaudal-fin photophores U-shaped (vs. three pronged) (Ref. 85782).

Meso- to bathypelagic; from 325 to 2700 m (mean 1631 m) (Ref. 85782).

Estimates based on models

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.2 se; based on size and trophs of closest relatives

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