Surprise discovery of Europe's first cave fish


Researchers reporting in Current Biology on April 3 have discovered the first European cave fish. A hobby cave diver first sighted the fish, a loach in the genus Barbatula, living in a hard-to-reach, underground water system in South Germany.

"The cave fish was found surprisingly far in the north in Southern Germany," says Jasminca Behrmann-Godel of Germany's University of Konstanz. "This is spectacular as it was believed before that the Pleistocene glaciations had prevented fish from colonizing subterranean habitats so far north."
