Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 8; Raggi dorsali molli (totale) : 8 - 9; Spine anali: 1; Raggi anali molli: 8 - 9. Characterized by having enlarged, thickened and wide pectoral fins; widely spaced broad fleshy pelvic fin; head and snout flattened, small dorsolaterally oriented eyes; small ventrally placed mouth; accessory lateral line canals dorsal and ventral to the lateral line on the body, including caudal fin base; caudal fin large (Ref. 92840).
Inhabits relatively steep gradient coastal streams in hilly or mountainous terrain. Feeds on algae and diatoms; effectively clings on rocks and boulders with its broadened pelvic and pectoral fins and flattened head and snout (Ref. 92840).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.8750 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
