Etymology: Cetonurichthys: Greek, ketos = a marine monster, whale + Greek, oura = tail + Greek, ichthys = fish (Ref. 45335); subinflatus: Named for the seismosensory canals of the head which are less inflated than in related genera (Ref. 41160).

Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 35909)
Ραχιαίες άκανθες (συνολικά) : 2; Μαλακές ραχιαίες ακτίνες (συνολικά) : 0. Head broad, shallow, interorbital 31-34% of HL; snout 36-42% HL, with paired tubercular scales at tip; suborbital 17-20% HL; ridge lacking stout scutelike scales; jaws short, upper jaw 24-28% HL, inferior; tooth rows short, crescent -shaped, outer premaxillary series enlarged. Cephalic sensory canal moderately dilated, lacking open pores; lateral line canal with modified scales, interrupted in places. Trunk scales small (11-13 rows between origin of first dorsal fin and lateral line), bearing erect spinules in no particular arrangement; scales along dorsal fins larger than surrounding ones; head completely scaled, including patches on gular and branchiostegal membranes. Spinous second ray of first dorsal fin with small serrations; outer ray of pelvic fins elongated. Anus midway between bases of anal and pelvic fins; periproct narrow; no dermal window of light organ. Eleven trunk vertebrae (Ref. 35909).
A benthic species found on the continental slope (Ref. 75154).
