Umbridae

Umbridae is a family of ray-finned fish in the order Salmoniformes. The single living genus, Umbra, occupies weed-choked freshwater habitats in eastern North America and eastern Europe. While the family traditionally contained the genera Umbra, Novumbra, and Dallia, recent genetic and paleontological research have recovered this grouping as paraphyletic, with Novumbra and Dallia being moved to the family Esocidae.

== Distribution == Umbridae contains three extant species, all within the genus Umbra: Umbra pygmaea, Umbra limi, and Umbra krameri. U. pygmaea can be found across the eastern United States and southeastern Canada. U. limi ranges throughout the Great Lakes region and Mississippi River basin of North America. U. krameri can be found in the Danube and Dniester River basins of Europe. Umbra spp. are most commonly found in the Atlantic coast regions of North America, along the marshy, low-oxygen areas of the Mississippi River, and in similar environments in Europe. All fossil specimens have been recovered from Europe, occupying similar niches to extant species.
