Etymology: Coelorinchus: Greek, koilos = a hollow + Greek, rhyngchos = jaw (Ref. 45335).
Environment / Climate / Range
Marine; bathydemersal; non-migratory; depth range 300 - 1000 m (Ref. 1371). Deep-water, preferred ?; 36°N - 20°N, 125°E - 140°E (Ref. 1371)
Northwest Pacific: southern Japan (Ref. 1371) and Taiwan (Ref. 54421). Possibly much wider in distribution.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 75.0 cm TL male/unsexed; (Ref. 1371)
spines: 0. Eyes very large; snout long, sharply pointed, its anterolateral margin completely supported by bone; head ridges prominently demarcated by stout, spiny scales; underside of head scaled. Light organ short. Overall color is grayish to brownish, without prominent markings; mouth cavity gray; gill cavities and distal third of the first dorsal fin blackish.
Larger individuals are found in deeper waters. Feeds on euphausiids, prawns, benthic fishes, isopods, and polychaetes.

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00129 - 0.00705), b=3.12 (2.93 - 3.31), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.52 se; Based on food items.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (64 of 100) .
