Snooty, the world’s oldest captive manatee, spent his final 48 hours making history and eating cake. The world famous sea cow turned 69 on Friday and celebrated another year in the Guinness Book of World Records with a blow-out party Saturday afternoon. Hundreds of guests sang him “Happy Birthday” at noon, like they’ve done every year at the South Florida Museum since 1993, then watched Snooty devour a cake-shaped tower of pineapple, strawberries and carrots. They clapped and cheered as the manatee – who had outlived his brethren in the wild by roughly half a century – used his abnormally strong pectoral muscles to climb on the edge of his 60,000 gallon tank and affectionately nuzzle his handlers. “We hope he keeps living,” Evangeline Boston told the local newspaper, “so we can keep seeing him.” But Snooty’s record setting 69th birthday would be the creature’s last. In the wee overnight hours, Snooty and his manatee tank-mates, Randall, Baca and Gale, managed to swim into an underwater hallway used to access plumbing for the exhibit’s life support system, officials with the Bradenton, Florida, museum said.
