The Flannelmouth Sucker

Flannelmouth Sucker is a native Colorado River basin fish associated with flowing water and varied river bottoms. Its range reaches from Wyoming south into the desert Southwest.

River Setting

Adults occupy rocky pools, runs and riffles of medium to large rivers. Smaller creeks are used less often. These habitat records describe a river fish that encounters changing current and depth, rather than one restricted to a single type of shallow riffle.

Distribution

Wyoming and Arizona mark widely separated parts of the Colorado basin distribution. The drainage connection matters more than a state name alone. Records from tributaries should retain their river identity, especially when comparing populations separated by reservoirs or other interruptions in the river network.

Length Evidence

The reference maximum is 56 centimeters including the tail, while a commonly cited length is 35 centimeters. A small published weight from a limited collection is not a reliable upper weight for the whole species. Length and mass should therefore be evaluated separately.

Keep the River with the Record

A tributary name adds useful context to a Flannelmouth Sucker observation, particularly when comparing fish from different parts of the Colorado basin.
