US park shares pictures of alligators with noses above frozen water
A video shared by 'The Swamp Park' shows alligators letting their body freeze in a US swamp in an attempt to survive the winter, only letting their snouts stick out of the water to breathe. This state is called brumation, wherein cold-blooded animals slow their metabolism and survive without food. In alligators, brumation can last from four to five months.
