Etymology: Catostomus: Greek, kata = down + Greek, stoma = mouth (Ref. 45335);  utawana: The name is of Onondaga origin, Utawana (utowana, oo-ta-wan’-ne) and translates as ‘‘big waves’’ (species author noted the the word meant sunshins which is a misconception) (Ref. 83995).

Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 11-12; Raggi anali molli: 7. Catostomus utawana is distinguished from C. commersonii by the following characters: eye diameter twice or less into snout length (vs. more than twice into snout length); caudal peduncle depth at terminus more than twice into anal-fin length (vs. less than twice into anal-fin length for a small individual); dorsolateral scales of with radii in the dorsal ventral, anterior, and posterior fields (vs. scales with radii in the anterior and posterior fields); individuals rarely exceed 200 mm SL (vs. non-stunted adults of much greater lengths for C. commersonii). In breeding condition, this species is distinguished from C. commersonii by the following characters: pearl organs on anal and caudal fins and on scales found near the anal fin and ventral areas of the caudal peduncle on females (vs. none); pearl organs on nearly every scale and on all fins for males (vs. pearl organs on anal fin, caudal fin, and scales between); males with gold stripe above a dark mid-lateral stripe on both sides, and a gold spot above each eye (vs. a longitudinal white stripe that turns vertically to cross the occipital region or the snout, and no spots dorsal to their eyes); females without stripes (vs. a yellow stripe that resembles the white stripe of male C. commersonii); breeding males and females no red coloration (vs. a scarlet stripe on both male and female) (Ref. 83995).

Biologia     Glossario (es. epibenthic)

Inhabits hilltop lakes and streams, but is no longer known from its type localities. Individuals spawn once per reproductive season that extends from early June to late July or early August. Preferentially use ephemeral streams for spawning. Arrival at streams is episodic, correlating to precipitation events and appropriate flow. Stream temperature appears to be less important a cue for reproductive behavior than other Catostomus. Females always have pearl organs when in breeding condition; retain drab coloration when spawning. Males develop a gold longitudinal stripe, small gold-colored patch above each eye, and are extensively covered in pearl organs when in breeding condition. Both sexes start to reach sexual maturity at about 4 years. Eggs are about 3mm in diameter (Ref. 83995).
