snail darter


n.

A small snail-eating darter (Percina tanasi) that formerly was found only in the Little Tennessee River. It was thought to have become extinct after construction of a dam, but later was discovered in several other Tennessee streams.


 
 

Rare species (Percina tanasi) of darter that originally was found only in the Little Tennessee River in the southeastern U.S. It became the subject of a legal controversy in 1978, when its status as an endangered species delayed for two years the construction of Tellico Dam. The situation was resolved when the fish was successfully introduced into the Hiwassee River.

Columbia Encyclopedia: snail darter,
a small, rare fish, Percina tanasi, discovered by a zoologist who was snorkeling in the Little Tennessee River upstream from the projected Tellico Dam. Dam opponents fought successfully to include the darter on the Endangered Species List in 1975 (see endangered species), and the dam was halted. In 1978, the Supreme Court sided with environmentalists, but Congress declared the fish nonendangered and the Tellico was built. Snail darters are classified in the phylum Chordata, subphylum Vertebrata, class Osteichthyes, order Percomorphi, family Percidae.
