Sequence divergences of Coquille River suckers from the others are 2.6-4.2%, suggesting a Pliocene separation based on
catostomid divergence estimates in Unmack and others (2014).

The Blue Sucker, Cycleptus elongatus (Lesueur) is a long, compressed and streamlined

The osteocranium of the
catostomid fish, Catostomus macrocheilus--a study in adaptation and natural relationship.
Although the pharyngeal teeth of small
catostomids may resemble those of small cyprinids, small
catostomids often have a fissure at the tip, whereas adult
catostomid pharyngeal teeth have a broad, flattened tip.
For example,
catostomid fishes represent a tetraploid lineage that originated about 50 mya, but only about 50% of isozyme loci in species of this group have been diploidized (Ferris 1984).
Interestingly, increased abundance of Creek Chubsuckers in a northwestern Mississippi stream in autumn (Shields et al, 1994) may have reflected upstream movements to the study site, and it may be that elimination of downstream connectivity inhibits colonization and movements of this small
catostomid. Similarly, Grass Pickerel have been previously found in greater abundance and size in unfragmented tributaries (Herbert and Gelwick, 2003; Guenther and Spacie, 2006), which may also reflect the proclivity of this species to move between larger downstream rivers and off-channel headwater habitats.
