... scientists have investigated this unusual predator-prey relationship between European catfish and pigeons in the Southwest region of France.
European catfish have been reported to capture the pigeons on land and drag them back into the water. This surprising behavior has not been known to occur in the native range of the species; however this article discovers that in France, where the fish are an invasive species, they have adapted their natural behavior in order to feed on novel prey in their new environment.
The researchers completed this study along the Tarn River in Southwestern France.
