A school of catfish in south western France appear to have taught themselves how to leap out of the water and catch pigeons to eat.
Catfish usually trawl the bottom of freshwater lakes and rivers for food, but scientists from the University of Toulouse have observed fish in the Karn River exhibiting very different behaviour.
Researchers spent five months watching the catfish from a bridge over the river and discovered they had adapted their hunting techniques to include pigeons amongst their prey.
Video shows the catfish squirming their way into shallow waters before lunging at birds.
The catfish temporarily beach themselves in the process, leading the researchers to dub them "freshwater killer whales".
After catching a pigeon, the catfish violently drag their prey back into the water.
The catfish's efforts succeeded 28 percent of the time.
