Michael Phelps has finally met his match in the water: a ''great white shark.''

The Olympic champion swimmer was bested Sunday night in the Discovery Channel's Shark Week special ''Phelps vs. Shark: Great Gold vs. Great White.''

But Phelps didn't swim with a real shark. He competed in the ocean against a computer-simulated fish based on data on the swimming speed of sharks.

Phelps was outfitted with a wetsuit and a monofin to mimic a shark's powerful tail. He finished the 100 meter race in 38 seconds, two seconds slower than the simulated shark.

Phelps tweeted Sunday that he'd like a rematch, but in warmer water.
