Wikipedia Abstract

The slimy sculpin, Cottus cognatus, is a freshwater species of fish that inhabits cool, rocky streams, rivers and lakes throughout northern North America and eastern Siberia. The slimy sculpin is found in freshwater and sometimes brackish water in areas with rocky or gravel type bottoms. The slimy sculpin is a nocturnal fish that usually spends most of its time on the stream bottom and seeks shelter under rocks and logs, especially during spawning season.
