Morphology | Morphometrics
(total): 2. Large, soft head inflated. Sensory canals on head with small pores. Dorsally scaleless snout extend to the level of the anterior nostril. Rudimentary barbel, less than 3% of head length (HL); orbit diameter about 28% HL; snout much longer than orbit, about 1.1 into the broad interorbital. Light organ poorly developed and visible only as a small, naked, black projection in front of the anus. Second spinous ray of first dorsal fin smooth. 1D II,9 (Ref. 11651).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00097 - 0.00495), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±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
): Low to moderate vulnerability (31 of 100) .
