Redside shiner

The redside shiner (Richardsonius balteatus) is a species of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. This fish is found in the Western United States and British Columbia. This species was first described by Sir John Richardson, a Scottish naturalist and naval surgeon. The type locality is from the Columbia River, and it is believed to have been sampled near Fort Vancouver. This species has a large native range, spanning from southern Utah to northern British Columbia. There are currently two subspecies (R. b. balteatus and R. b. hydrophlox), but phylogeographic analysis based on mitochondrial DNA sequence data suggests that there are three main clades, therefore the two subspecies taxonomy may not accurately reflect the evolution of the group. However, a formal taxonomic update has not been made.
