Dozens of cold-stunned turtles were flown from the cold waters of Cape Cod down to the Florida Keys and brought to the Turtle Hospital in Marathon over Thanksgiving weekend. The 40 rescued turtles were Kemp’s Ridley sea turtles, one of the most endangered sea turtle species. LIVE at the Turtle Hospital 40 cold stunned Kemps Ridley sea turtles checked in last night and are warming up in the Florida Keys sunshine! Being “cold stunned” can leave lasting impacts on the turtles and recovery can take anywhere from 30 days to a year. So far, all 40 turtles have passed their swim tests, meaning they have no immediate threats to their health.
