生物學特性     字彙 (例如 epibenthic)

Lives among cobbles and rocks in swiftly flowing water (Ref. 52193). Active at night, feeding on benthic stream invertebrates such as mayfly and midge larvae (Ref. 52193). Breeds in summer (Ref. 52193). Iteroparous, with asynchronous ovarian development (Ref. 51405). Preyed upon by trout and is now scarce in certain streams (Ref. 7248, 52193).

在很快流動的水圓石與岩石之中生存。 活躍的在晚上, 吃底棲的水流無脊椎動物例如孚游類與蚊仔魚。 繁殖於夏天。 反復生殖的, 藉由非同步的卵巢發展.(參考文獻 51405) 被鱒魚捕食了而且在特定的溪流中是現在難得的。 (參考文獻 7248)
