Analysis of information sources in references of the Wikipedia article "Snail darter" in English language version.
"There is, technically, no snail darter," said Thomas Near, curator of ichthyology at the Yale Peabody Museum [...] the snail darter, Percina tanasi, is neither a distinct species nor a subspecies. Rather, it is an eastern population of Percina uranidea [...] early researchers "squinted their eyes a bit" when describing the fish, because it represented a way to fight the Tennessee Valley Authority's plan to build the Tellico Dam
A new study by Yale researchers shows that the tiny fish, discovered in a lower stretch of the Little Tennessee River in 1973, is not a distinct species at all, meaning it was never endangered.
