Huge Sharks 'Fly' Like Fighter Pilots
Monster sharks can execute underwater "flight" moves that would have put some fighter pilots to shame, two researchers announced this week.
Normally seen cruising slowly at the surface, the whale shark, which does not harm humans, can transform in the deep, hurling itself into a swift, steep dive like a pilot, soaring up and then down again in a series of great bounds, said researcher Rory Wilson of Swansea University in the Wales.
Whale sharks are the world's biggest fish. They are not whales or mammals.
