Short description

Anal soft rays: 13 - 14. Differs from all other species of Cottus in Europe by possessing spatulate prickles; pelvic-fin rays tessellated, with 5-15 distinct rows of spot, appearing as transverse bands; and 2 chin pores. Additional characters useful in the identification of this species include: lateral line clearly above midline of body (shared only with C. koshewnikowi); lateral line clearly above midline of body; lateral line incomplete, usually reaching to anal-fin base; and prickling restricted to body under pectoral fin (Ref. 55856).

Found in fast-flowing waters of coastal streams, rivers, inland lakes, usually on stony bottoms (Ref. 4698). Moves downstream to estuaries and tolerates brackish waters (Ref. 4698). Feeds on algae (diatoms, desmids, blue-green algae), polychaetes, crustaceans, aquatic insect larvae and nymphs (Ephemeroptera, Trichoptera, Plecoptera, Chironomidae), fish eggs and larvae.
