Biologi     Ordlista (t.ex. 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).
