The mottled sculpin (Cottus bairdi) lives in shallow, cold water throughout Yellowstone except in the Yellowstone River above Lower Falls and in Yellowstone Lake. This species eats small insects and some fish, and is consumed by trout.
Lives in rivers and streams with deep pools, clear and clean water.
Yellowstone’s minnows are small fish living in a variety of habitats and eating a variety of foods.
Suckers are bottom-dwelling fish that use ridges on their jaws to scrape flora and fauna from rocks.
