View from the blog-o-sphereWintering Wood Frogs Freeze Solid

By Karen McDonald – Shorelines – January 2, 2014
Here in North America there are a wide variety of toads and frogs, but perhaps none are so unusual as the wood frog. These frogs are found in Eastern North America, Canada, and up into Alaska. On a warm spring night you might hear them singing near bogs, vernal pools or upland forests, but something remarkable happens to them this time of year in the winter: They freeze solid. Now freezing solid isn’t remarkable by itself, but what is remarkable is that the frogs will literally come back to life in the spring, after having no heartbeat or brain activity (they don’t even breathe) for up to eight weeks! This baffles and amazes scientists, who are actively studying them even now. For full blog post,
