Morphology | Morphometrics
soft rays: 59 - 64;
Vertebrae: 43 - 44. Neural spine of second pre-caudal vertebra very long and curved anteriorly reaching to about one-half the length of the neurocranium; caudal fin entirely free from dorsal and anal fins, eyed side posterior nostril tube-like with a small pore opening just above labial groove. Pectoral fins filiform with less than four rays. Body pale brown in color with a variable number (3-5) of darker blotches along the body midline, along the dorsal fin (4-6) and the anal fin (3-5). More or less longitudinal rows of blotches are often observed on well-pigmented specimens. Branchial cavity and peritoneum darkly pigmented.
Minimum depth from Ref. 58018.

Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00466 - 0.02049), b=3.08 (2.90 - 3.26), 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. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (25 of 100) .
