生物学特性     字汇 (例如 epibenthic)

A typical inhabitant of black or clear waters, usually in forest streams with moderate to swift current flow over firm sand or gravel bottoms (Ref. 7462). Lives hidden under plants, litter or plant debris. Can easily be mistaken as a piece of dead wood when it rests on its side, motionless on the bottom. Often swims on one side in undulating movements (Ref. 35381). Feeds mainly on terrestrial insects, particularly ants (Ref. 7462). Nocturnal (Ref. 6868).

典型栖居动物黑色或水流清澈的通常在森林溪流有中等的到湍急的水流流动硬沙之上或砾石底部.(参考文献 7462) 在植物,胎窝或植物残枝下面藏的生命。 能容易地被误认作为一个枯木的块当它停留在它的侧边上面的时候, 不动的在底部上。 时常在波浪形的运动的一个侧边上游泳。 (参考文献 35381) 主要吃陆栖的昆虫, 特别地蚂蚁.(参考文献 7462) 夜行的.(参考文献 6868)
