Catfish the size of a Grizzly Bear
How's this for a catch: at 646 pounds, this giant 9-foot catfish from the Mekong River in Thailand is not only the largest freshwater fish ever caught, it's about the size of an adult male grizzly bear. You can more read about the fish here and here.
I found it funny that while "environmentalists and officials negotiated for its release to allow it to spawn" (guys, a fish this size has been spawning for a LONG time already!), the fish "died and was eaten by the fisherman" (which is WHY they were fishing! They were HUNGRY!!!). I wonder how many people a fish that size would feed?
