One step away from being land sharks
Catfish found to beach themselves, orca-like, to catch land birds
The study, conducted largely by scientists from the University of Toulouse, is titled "Freshwater Killer Whales" and describes the beaching behavior of European catfish on the River Tarn in France. The study's abstract section states: "Among a total of 45 beaching behaviors observed and filmed, 28 percent were successful in bird capture."
Study subjects were Wels catfish (Silurus glanis), an invasive or non-native species, and their peculiar behavior is an example of an introduced species adapting to a new environment in order to survive. Native catfish in the river did not exhibit beaching behavior as a prey strategy.
