Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 13; Raios anais : 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).
Body shape (shape guide): elongated.
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).
