The manatee death toll is now four this winter after scientists found another dead manatee in area waters this weekend. The pregnant female was found on Perdido Key, Fla. State officials asked the Dauphin Island Sea Lab's Manatee Sighting Network to perform a necropsy. The animal will be tested for exposure to oil, but scientists said the most likely cause of death was stress related to cold weather. (Source:
