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 Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 7 - 10; Mjukstrålar i ryggfenan (totalt): 23-26; Mjukstrålar i analfenan: 23 - 26. This species is characterized by the following: dark orobranchial cavity; inclined teeth in the marginal row on the premaxillary are increased in size in the postorbital portion of the bone; presence of teeth on tongue; minute gill rakers usually absent on first gill arch; reduced maxillary (suborbital) photophores disconnected with anteropreopercular photophores; no posteropreopercular photophores and transverse ventral (interventral) photophores; thin cranial roofing bones; short upper jaw, 60.0-71.4% head length (HL), usually less than 66% HL (75% of specimens; mean 65.6%); short pectoral fins, 12.5-21.4% SL, usually less than 16% (88% of specimens; mean 14.9%); group of 4 pores above the second nare; modally 36 vertebrae (Ref. 78617).

Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 6.5, mean 2.3 °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 (11 of 100).
