Nothonotus is a subgenus of the genus Etheostoma. Species from this subgenus have a heavier body as opposed to other darters. They also have a thick caudal peduncle. Nothonotus species also differ from other darters through the mean number of alleles, percentage of polymorphic loci and average heterozygosity.[1]
Habitat
Their habitat is mainly the area around Alabama and Georgia, specificially in the Mobile Basin and the Gulf Coastal Plain. It is assumed that the earliest Nothonotus fishes were native in the Mobile Basin. Today's fishes also populate the Tennessee River and Coosa River.[1]
