Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 2; Mjukstrålar i ryggfenan (totalt): 7; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 3 - 4. Body coloration brown to black, with large white to yellow spots on the sides. Ventral surface from head to anus largely naked in adults, few small platelets on skin ventral to pectoral girdle. Lateral plates unkeeled although ventral row may have moderately elongate odontodes forming 1 or more keel-like rows on caudal peduncle. Cheek plates with 20-40 hypertrophied odontodes in adults. Caudal fin emarginate. Lateral line plates 22-24; below dorsal fin 7-8; interdorsal 3-5; adipose caudal 8-10; postanal 11-13; caudal peduncle 5.
Specimens collected from rocks and rapids. Stomach contents include algae and detritus; also seeds (dicotyledonous and monocotyledonous seeds) (Ref. 41483).
