Lythrurus alegnotus (common name Warrior shiner) is a species of fish that is native to Alabama.[1]

Description

The shiner has a compressed body with large eyes and dark lips and chin. The upper body of the shiner has dark stripe and dots, and is a light olive color. The shiner is distinguishable from Lythrurus bellus due to the dark strip around the side of the Lythrurus alegnotus. The shiner is about 7.5 centimeters, with eleven to twelve anal fins. Breeding males have red colored fins.[2]

Taxonomy

Lythrurus alegnotus was originally treated as a sub-species of Lythrurus bellus. However, it has since been treated as a unique species by a number of sources.[3]

Habitat

The shiner lives in small to medium sized freshwater streams with minimal gradient and substrate ranging from sand to bedrock. The shiner prefers to live in deep pools that are downstream from water willows.[1] The fish mainly lives in the Black Warrior River system in Alabama. Populations of Lythrurus alegnotus co-exist with populations of Lythrurus bellus in Lost Creek in Walker County, Alabama, the North River, and in Yellow Creek and Hurricane Creek in Tuscaloosa County, Alabama.[1]

Conservation status

The shiner is rated as near-threatened by the International Union for Conservation of Nature. Its habitat range is less than 7,500 square kilometers, and many local populations of Lythrurus alegnotus have gone extinct due to the continued degradation of stream quality and the effects of strip-mining.[1] The shiner is not considered to be vulnerable because of the existence of more than ten population centers and the lack of fragmentation in population distribution. However, the IUCN still recommends the continued monitoring of Lythrurus alegnotus populations and their habitat.[1]
