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).

ສັດທະເລ ກ່ຽວກັບ (ຢູ່) ຊັ້ນນ້ຳໃນທະເລເປີດທີ່ປອດແສງສ່ອງເຖິງ; ລະດັບຄວາມເລິກ 30 - 2390 m (Ref. 56658), usually 50 - 1870 m (Ref. 85782). Deep-water; 46°N - 36°S, 0°E - 0°W
Circum sub- and tropical: Atlantic Ocean (from 46°N-36°S, 7°W-88°W). Pacific Ocean (33°N-27°S, 99°W-121°E), including off Japan and several records from the Western Indian Ocean (Ref. 85782). The northern occurrence in Atlantic and Pacific most likely due to transportation by Gulf Stream and Kuroshio, resp. (Ref. 78616).

Body shape (shape guide): fusiform / normal.
A meso- to bathypelagic (Ref. 85782). One record at 4,631m deep (Ref. 78616).
