– A small parade of rescued young sea turtles has headed into the Gulf of Mexico from Louisiana — a bright note in a tough season for sea turtles. Sea turtles get cold-stunned and lethargic when the water around them chills down so fast they can’t swim to warmer waters. Those released this week at Grand Isle were Kemp's ridley sea turtles, like most of those injured in New England, where volunteers rescued 775 turtles, said Kate Sampson, regional sea turtle stranding coordinator for the National Oceanic and Atmospheric Administration. The Texas turtles were likely in relatively good shape because the cold came on so quickly, she said. AdSo many green and Kemp’s ridley sea turtles were found off Texas in February that the South Padre Island Convention Center was used as an emergency sea turtle hospital.
