This fascinating video shows Wels catfish (Silurus glanis) using the beaching behaviour seen in Killer whales to catch pigeons on land.

If was filmed in the Tarn River in southwestern France — Wels catfish were introduced there in 1983 and have since established self-sustained populations.

French researchers witnessed 45 instances of the catfish beaching — with 28% of these being successful.

Researchers say this behaviour hasn't been observed in the native range of these fish, and that their results suggest some individuals in introduced populations may adapt their behaviour so they can capture novel prey in new environments.
