European catfish have been eating
their food source and they need another one, what do they go after, Pigeons.
There have been studies of catfish and they have recorded 58 times that they
have successfully captured and ate the pigeons. The catfish would swim close to
the shore and jump at the birds, then drag them back into the water and consume them. The killer catfish has been compared with the bottlenose dolphin. the bottlenose dolphin would chase fish to the land, also the Argentinian killer whale, that goes to beaches to catch sea lions.
