It’s not just humans who have to brave the cold weather as temperatures drop. Each year beach walkers from the Massachusetts Audubon Sanctuary on Cape Cod are on the lookout for stranded sea turtles suffering from hypothermia.

Two such sea turtles, weighing 3 and 5 pounds, were taken to the New England Aquarium’s Animal Care Center in Quincy for treatment after they were found in Dennis and Brewster Tuesday with body temperatures of less than 58 degrees.
