Status
Critically Endangered
Scientific name
Percina jenkinsi
Taxonomy
Perciformes · Percidae · Percina

Appearance

The curious snout development is an apparent adaptation to stone-flipping behavior, in that the snout is used to flip over rocks during feeding. Unlike many other darter species, logperches show little sexual dimorphism in coloration.

This is a slender fish with a maximum length of 4.6 inches (12 cm).

Range and habitat

The Conasauga logperch is currently known only from an 11-mile reach of the Conasauga River, a Coosa River tributary in northern Georgia and south-central Tennessee. Specifically, it exists in the Conasauga River from the confluence of Half-way Branch with the Conasauga River in Polk County, Tennessee, downstream approximately 11 miles through Bradley County, Tennessee, to the Georgia State Highway 2 bridge in Murray County, Georgia. It is endemic to the United States.

Diet and breeding

Logperch feed on a variety of invertebrates. This species feeds on aquatic invertebrates found under stones.

It is known to flip over substrate and prey on disturbed invertebrates. Young feed on microcrustaceans. Sexual maturity is reached after one year and spawning occurs in spring, in fast riffles over gravel substrate.

In crisis

It has been listed as endangered throughout its range with critical habitat under the U.S. Endangered Species Act since August 5, 1985.
