Morphology | Morphometrics
Vertebrae: 180 - 185. This moderately elongate species of Ophichthus, subgenus Coecilophis is distinguished by the following characters: tail 59-60%, head 9.6-10.1% of total length and body depth at gill opening 3.2-3.7% of TL; origin of dorsal-fin above mid pectoral fin; elongate pectoral fin, non-filamentous; posterior margin or orbit in advance of rictus; posterior nostril a hole above upper lip is covered by a flap; no lip barbels; small but conspicuous head pores, SO 1+4, IO 4+2, POM 2+5; small, conical teeth, biserial on anterior vomer and jaws; uniform gray brown in color, lighter ventrally, fins pale except anal which has a dark patch at posterior base; mean vertebral formula 15/66/182, total vertebrae 180-185 (Ref. 84366).
Benthic on fine sand or hard substrata with crevices (Ref. 58302).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00129 (0.00054 - 0.00308), b=2.92 (2.72 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.7 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 (29 of 100) .
