Lez Sculpin

Cottus petiti, also called the chabot du Lez in French, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to France, found only in a small 3 km stretch of the river Lez in Southern France near Montpellier. The natural habitat is fed by karstic springs which may have enabled the isolated survival of the population through geological history.

Now the species may be threatened by habitat loss. The males of this species are typically 56 mm (2.2 in) in length. This species was confirmed as a separate species from the European bullhead in 2005 by Jörg Freyhof, Maurice Kottelat and Arne W.

Nolte.

Cottus petiti inhabits cool, clear freshwater streams and rivers with rocky substrates and moderate to fast-flowing water. The species requires well-oxygenated waters with gravel beds for spawning and rocky crevices for shelter.
