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); cordilluminatus: Name from Latin ‘cordis’ meaning heart and ‘luminosus’ for full of light, referring to the heart-shaped ‘saf’.

संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
जानवरों की रीड़ का जोड़: 35 - 36. This species of the Pseudoscopelus scriptus species group is distinguished by the unique dentition pattern of the premaxilla: mesial series in rows of 2-3 teeth, with first and second teeth much smaller than innermost tooth (vs. single row in P. pierbartus and P. obtusifrons; and teeth gradually increasing in size in P. cephalus, P. sagamianus, and P. scriptus). It is further distinguished from P. scriptus with anal-fin photophores (or saf) extending anteriorly beyond and around anus (vs. saf not extending anteriorly to anus); from P. cephalus by vertebral count (total vertebrae 35-36, precaudal 18-19 vs. 31, 14 in P. cephalus ); from P. sagamianus by melanophores inside mouth restricted to tooth insertion region (vs. internal area of mouth and gill arches completely black) (Ref. 85782).
Body shape (shape guide): elongated.
A meso- to bathypelagic, from 537 to 1164 m (mean 954 m) (Ref. 85782).
