Tonguetied Minnow

Tonguetied Minnow

Exoglossum laurae

Tonguetied Minnow is found in small to medium-sized streams with clean gravel and is native to 2 of 18 watersheds. Losses of range have occurred in parts of the Allegheny watershed and there has been a dramatic decline in frequency occurrence from comprehensive stream surveys between 1930s and 2000s. Although never abundant, decline is not obvious in the Genesee watershed, where it is present at up-river sites.
