An expansive sampling effort with multiple gears is warranted not only at historic collecting sites but throughout the Pearl River system to evaluate available habitat and current status of this catostomid
, as well as the river redhorse Moxostoma carinatum, which has also declined precipitously in several systems throughout its range (Ross, 2001; Adams et al.

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

Tetraploidy and the evolution of catostomid
The acanthocephalan genus Neoechinorhynchus in the catostomid
fishes of North America, with descriptions of two new species.
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).
Most of the USNM lots are of no particular historical importance, but some have been determined to comprise type material, including a few nominal North American cyprinid, catostomid
, and centrarchid species (Gilbert 1998).
