Short description Morphology | Morphometrics

Vertebrae: 134 - 139. This moderately elongate species of Ophichthus, subgenus Coecilophis is distinguished by the following characters: tail 53-58%, head 11-13% of total length and depth at gill opening 4.0-4.8% of TL; origin of dorsal-fin slightly behind pectoral-tips; pectoral fins spatulate, non-elongate and slightly less than length; large eyes, posterior margin of orbit ahead of rictus; posterior nostril a hole in upper lip and covered by a flap; small, inconspicuous head pores, SO 1+3, IO 4+2, POM 2-3+6-7 (usually 3+7); small, conical teeth, uniserial on mandible and vomer, few anterior teeth on maxillary; color tan on flanks and dorsum, pale ventrally, all fins and anterior nostrils pale, chin and snout dusky; mean vertebral formula 16.2/54.0/136.5, total vertebrae 134-139 (Ref. 84366).

Biology     Glossary (e.g. epibenthic)

Taken from great depths, rarely from shallow muddy bottoms. Feeds on benthic animals (Ref. 637).

Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 19.9, mean 13.2 °C (based on 353 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (45 of 100).
