Morphology | Morphometrics
A species of Coelorinchus with two dermal windows of light organ, one immediately before
anus, the other in a shallow fossa on chest just behind isthmus, the two windows not connected by an externally visible black mesial line; snout moderately elongated, 1.4–1.7 times orbit diameter, tipped with a sharp terminal scute, anterolateral margins incompletely supported by bone; underside of head fully naked except for scales along anterolateral snout margin and occasional isolated cluster below junction of preopercle and infraorbital ridges (above angle of lower jaw); rays of second dorsal fin high, about equal to opposite members of anal fin; spinules on body scales small, in 10–14 parallel rows; about 8–11 saddle bands on body; branchiostegal membranes prominently black or blackish, chest and abdomen blue; gums and upper oral valve dark (Ref. 83367).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (42 of 100) .
