Catfish Strands Itself To Kill Pigeons

I've seen the sterotypical scene of a momma duck and her babies floating out along behind her, touring the pond in the shallows....

And then a big swirl, maybe a splash, and there is one less duckling in the parade...

Only difference is these catfish are going where they don't really belong to do it. I'm assuming that the same species in other locations doesn't display the same behavior on a fairly regular basis...
