Bear Lake Sculpin
Cottus extensus
The Bear Lake sculpin, Cottus extensus, occasionally referred to incorrectly as a "bullhead", is a species of freshwater sculpin endemic to Bear Lake on the Utah-Idaho border. It is one of only four sculpins native to Utah, and the only extant lake-dwelling sculpin in Utah (see Utah Lake sculpin). Although the fish is only native to Bear Lake, it has been introduced and established in Flaming Gorge Reservoir.
