With the thermometer reading 18° this morning, it is hard to believe that within a few weeks the loud quack-like call of male Wood Frogs will be coming from The Preserve’s vernal pools. What is still harder to believe is that right now those frogs are frozen. Yes, actually frozen solid. Wood Frogs are one of the only vertebrates to evolve this ability. This two minute video shows a Wood Frog thawing and coming “back to life.”
Although the bio-chemistry that Wood Frogs have evolved to do this is still being worked out, it is amazing what scientists have discovered to date. Read more about the bio-chemistry of Wood Frogs freezing.
