To complete this weeks' trifecta of bizarre animal stories: following dogs who drive cars and parrots who drive robotic buggies, the "Not Exactly Rocket Science" blog at Discover reports on catfish that temporarily strand themselves on land to hunt pigeons:
As the River Tarn winds through the city of Albi, it contains a small gravel island where pigeons gather to clean and bathe. And patrolling the island are European catfish—1 to 1.5 metres long, and the largest freshwater fish on the continent. These particular catfish have taken to lunging out of the water, grabbing a pigeon, and then wriggling back into the water to swallow their prey.
I guess the land-shark is only a matter of time now. So if someone knocks at the door and says, "Candygram", don't let them in!
