Cottus rondeleti

provided by wikipedia EN

Cottus rondeleti is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is endemic to the coastal Hérault drainage of Southern France. The total known distribution comprises three distinct short stretches of stream, and the species considered critically endangered because of threat of drought that is promoted by water extraction and potentially by climate change.

This species was described as a separate species from the European bullhead (C. gobio) in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W. Nolte.[2] The specific name honours Guillaume Rondelet, a pioneer of European ichthyology.[3]
