The snail darter (Percina tanasi) was first described as a distinct species in 1976 by David A. Etnier and became famous as the subject of a landmark environmental law case under the Endangered Species Act. However, recent research has challenged its status as a separate species.
A 2025 Yale study suggests that what we know as the snail darter may actually be a subpopulation of the stargazing darter (Percina uranidea), rather than a distinct species. This finding has sparked scientific debate about the fish's taxonomic classification.
Do you think the snail darter is real?
1,000Probably could've made this a market instead of a poll for people to predict the outcome (It's your choice, but I just feel like a market would've been more fitting).
That aside, I feel like there's definitely a good chance it's not a separate species - the Wikipedia talk page doesn't really have a counterargument and some sources say the Snail Darter might have been concieved to prevent the building of a dam.
