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).

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 17 - 22; Anal soft rays: 17 - 20. This species can be distinguished from its congeners by having suprapectoral-fin photophores (vs. absent) and the anterior teeth of lateral series in dentary and premaxillary are hook-like curved, inserting on the lateral edge of bone and positioned outside of mouth so that teeth are visible in ventral and dorsal views (vs. teeth straight, or if curved, not hook-like, and inserted at oral edge of bone, not allowing them to be seen in dorsal or ventral views) (Ref. 85782).

Estimates based on models

Preferred temperature (Ref. 123201): 4.5 - 11, mean 6.5 °C (based on 438 cells).

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): 3.7 ±0.2 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
