Description
(Dec 3, 2020) Unlike frogs, turtles don't hibernate through the winter. In fact, sometimes you can see snappers and other species moving around under the ice. While their metabolism runs at very low ebb in the cold, they remain alert to changes in light and temperature that signal the coming spring.
How do they survive without oxygen? As Paul Smith's College biologist Curt Stager tells Martha Foley, they get energy from their body tissues, and their shells neutralize the resulting lactic acid build-up.
