簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 12-13; 臀鰭軟條: 8 - 9. Its dark olive dorsal surface and light golden ventral surface are sharply divided at the lower edge of the lateral line scale row. Its has relatively narrow mouth without barbels or with one pair of minute posterior barbels. The unbranched dorsal ray is flexible.
它的深色橄欖色背面與淡金色的腹面銳利地在側線鱗片列的下面邊緣被分開。 它的有相當沒有觸鬚的狹窄的嘴或和一對細小的在後部的觸鬚。 不分枝的背鰭鰭條是柔韌有彈性的。
Occurs in fast flowing stretches of river and deeper pools. Common particularly in rocky pools. Feeds by scraping algae off rocks with its horny lower jaw. Varicorhinus xyrocheilus occurs sympatrically and syntopically with V. dimidiatus.
