The world of catfish has changed.

Putting the Catfish amongst the Pigeons

In Southwestern France, a group of fish have learned how to kill birds. As the River Tarn winds through the city of Albi, it contains a small gravel island where pigeons gather to clean and bathe. And patrolling the island are European catfish—1 to 1.5 metres long, and the largest freshwater fish on the continent. These particular catfish have taken to lunging out of the water, grabbing a pigeon, and then wriggling back into the water to swallow their prey. In the process, they temporarily strand themselves on land for a few seconds.

Catfish get their name for the long, sensitive whiskers (or ‘barbels’) on their upper jaws, and the Tarn fishes would erect theirs when they were hunting pigeons. This, combined with the fact that only moving pigeons were ever attacked, suggests that the fish are sensing the vibrations of birds that approached the water.
