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); lavenbergi: Named after Robert J. Lavenberg, for his contribution to the knowledge of the genus Pseudoscopelus..

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 8; Mjukstrålar i ryggfenan (totalt): 23-25; Ryggkotor: 37 - 39. Differs from other species of the genus by the following three unique characters: random trunk photophores in broad band of three or more rows; postventral-fin photophores short, not extending to anus, and reaching anteriorly to very close to pelvic-fin origin; absence of maxillary photophores and presence of anteropreopercular photophores (Ref. 75982).

Estimates based on models

Preferred temperature (Ref. 123201): 5.1 - 11.1, mean 7.8 °C (based on 32 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).

Trofisk nivå (Ref. 69278): 3.7 ±0.2 se; based on size and trophs of closest relatives

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