Short description
Identification keys | Morphology | Morphometrics
Vertebrae: 35 - 36. This species is distinguished from its congeners by the following set of characters: dorsal head profile straight from nape above eye to upper lip tip; posterior angle of jaws extending to between a vertical line drawn through anterior edge of eye and a vertical line drawn through anterior part of eye; infraorbital invagination vertical to posterior part of eye; posterior opercular edge w-shaped with two equally long tips; longitudinal infralateral and suborbital transversal rows of superficial neuromasts are in the well-defined deep groove; trunk cross-section behind pectoral fin base half oval with straight ventral side; body granules shallow and inconspicuous; upper attachment of gill membrane is opposite to 5th to 6th pectoral ray; pectoral rays 17-19; upper attachment of disc membrane attaching to base of pectoral fin at 16th-18th pectoral ray; principal caudal rays 10-11; head length 25.0-28.9% of SL; pectoral fin length 8.2-10.3% of SL; prepectoral distance 24.7-28.2% of SL; ventral adhesive disc length 14.9-19.0% SL; caudal-fin length 14.2-17.5% of SL; low number of vertebrae 35-36; pharyngeal jaws with small ceratobranchial 5, having a few hardly recognizable small conical teeth; nasal bones with inconspicuous frontal end; in life with star-like pigmentation around eyes, body colouration dark, sometimes marbled or with stripes (Ref. 123696).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00202 - 0.01305), b=3.11 (2.89 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
