Short description
Morfologia | Morfometria
Raggi dorsali molli (totale): 9; Raggi anali molli: 7; Vertebre: 38 - 39. This species can be distinguished from its congeners by this set of characters: the most elongated body, body depth/SL 8.62-10.68% (vs. 11.70-16.55%); eyeless; caudal fin forked; well-developed adipose crests on caudal peduncle; body naked and de-pigmented. It is similar to O. translucens by lacking eyes and with forked caudal fin, but differs from the latter by the appearance of anterior nostril (long nostril tube and barbel of the anterior nostril, 18.6-26.3% HL) and caudal crests (adipose and not transparent) as well as more counts of vertebrae (4+38-39 vs. 4+32) (Ref. 88136).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00385 - 0.01971), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
