Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

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):  PD50 = 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. 59153):  Low vulnerability (21 of 100).
Price category (Ref. 80766):   Unknown.
