Bionic Dolphin

"The bionic dolphin is part speed boat, part submarine. It seats two people and is powered by a 425-horsepower Corvette engine. It can stand upright (just like Flipper), cruise at 55mph, and is constructed of Kevlar. Its creator, Thomas Rowe, is still awaiting approval before he can start cranking them out, but expect to pay up to $350,000 clams for this aquatic beast. " - engadget
