scary catfish

I just read a headline about a species of catfish that hunts pigeons by the river Tarn in France.
Horrifying!
Those poor pigeons!
Catfish for the most part are predators.
I have a bristle nose catfish in my aquarium that eats snails. The population of snails in my tank had grown so out of control  I had to add a bristle nose catfish and a clown loach to control the population.
The Amazon river boosts some of the most diverse and unusual fish species.
As pictured above is the "pralba". It is the world's largest catfish at 3M long. They have been known to tip over canoes and swallow small children on board.
The amazon also "hosts" the world smallest catfish- the candiru. This little sucker is only 2cm long (the size of the splinter)and is notorious for swimming up urethra's (yup, not just cattle but humans too)  causing some serious and painful damage.
But back to the topic of this catfish hunting pigeons. You have got to wonder if this catfish has been doing this all along  and a cameraman just noticed it or if it had (recently) taught itself that this was a 'food source".
Regardless, those poor pigeons!
