Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:The flannelmouth sucker is a bottom feeder. It is reported to feed on diatoms, algae, fragments of higher plants, seeds, and benthic invertebrates (Sigler and Miller 1963, Lee et al. 1980). See Tyus and Minckley 1988 for possible importance of Mormon cricket as a food source.
Phenology Comments:
Reproduction Comments:
Migration Mobility:
Habitat Comments:The flannelmouth sucker inhabits moderate to large rivers. It is seldom found in small creeks and is absent from impoundments. This species is typical of pools and deeper runs and often enters mouths of small tributaries (Lee et al. 1980) in addition to riffles and backwaters (Sublette et al. 1990). Young are usually found in shallower water than are adults (Sigler and Miller 1963). It spawns in riffles, usually over a substrate of coarse gravel (Lee et al. 1980).
Ecology comments:Flannelmouth sucker adults can be highly mobile, traveling several hundred miles in undammed river systems such as the Green River. Studies of flannelmouth below Davis Dam in the lower Colorado River have shown seasonal movement of up to 16 miles (Best and Lantow 2010).
