Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 13; Anal soft rays: 8. With peculiar mouth structure: both jaws covered by a horny sheath and with sharp edges; upper jaw without processus dentiformis and lower jaw without notch; lips very thin and wide, not completely covering jaws; intestine with numerous loops. This peculiar mouth structure enables the fish to scrape aufwuchs (Ref. 39226).
Collected from a small stream about 3-5 m wide, in a narrow valley, up to 60 cm deep with moderate (in pools) to swift (in riffles) current, over sand and pebbles (pools) or boulders and pebbles (riffles). The stomach and intestine of a 4.17 cm SL fish contained vegetable remains (Ref. 39226).

50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00336 - 0.01491), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
