Usually, it’s “Bird eating fish” but here we have a case of a “Bird-eating fish.”
The Wels Catfish, Silurus glanis, is the second largest fish in its range, which covers much of Europe and parts of West Asia. In parts of Western Europe, it is considered to be “exotic” because it has been introduced, possibly by anglers, in lakes and rivers in France and the Iberian Peninsula. It has also found its way to Japan where it is considered to be an invasive species. It is sometimes known as the European Catfish.
