No, I didn't get that backwards. Usually it's the bird that swoops down and snatches a fish from the water. In this case, a tigerfish actually grabs a low-flying bird for an easy meal, in what researchers are saying is the first recorded occurrence of a freshwater animal preying on a bird in flight. (The story continues below the video.)
The researchers studying tigerfish habitat and migration in the Mapungubwe National Park, near the border with Botswana and Zimbabwe, observed up to 20 fish catching barn swallows every day they were there.
