簡単な記述
形態学 | 形態計測学
臀鰭: 5; 脊つい: 27 - 28. Hypostomus yaku can be diagnosed from all congeners by having the five lateral series of plates with hypertrophied odontodes, not aligned in longitudinal rows, more conspicuous on flanks of caudal peduncle of the larger specimens (vs. lateral series of plates without hypertrophied odontodes or with aligned hypertrophied odontodes only along the longitudinal keels) (Ref. 97842).
Facultative air-breathing in the genus (Ref. 126274); The type locality, Rio Quente, has a width of about 3 m and depth of 1.0-1.5 m, moderate flow and bottom with sand, pebbles and rocks. Associated mainly with rocks. Seems to be restricted to warm waters. Collected together with Characidium xanthopterum, Characidium aff. zebra, Knodus moenkhausii, an undescribed species of a putatively new genus of the Characidae, and the exotic Xiphophorus helleri and Oreochromis niloticus (Ref. 97842).
