The baby sharks, bred at a gargantuan luxury resort on Dubai's artificial palm-shaped island, had never before encountered the open sea. But on Thursday, the tiny carpet sharks were jolted out of their warm pools at the flashy Atlantis Hotel aquarium to travel farther than they ever have in their two years of existence. A team of Dubai conservationists gingerly caught the sharks with nets and moved them into oxidized tanks in a Ford pick-up truck.
