Catfish or Shark?

My sister sent me an article from The Chattanoogan that featured this photo and blurb.

Attached are a couple of photos of a monster blue catfish caught near Greenville, Mississippi by an elderly man who let the fish go after his wife took the pictures. The weight of the catfish is unknown, though some catfish anglers guessed it to be at least 150 pounds. It looks like 200 pounds to me. For sure it would have been a new world record.

I don't know about any of you, but I wouldn't want to brush up against that while swimming in the water.
