Most animals deal with winter by migrating, hibernating, or simply growing a thicker coat. But wood frogs, native to the northern forests of Alaska and Canada — take more extreme measures: They freeze themselves solid to survive the frigid winters. The animals achieve this seemingly miraculous biological feat by pumping their body tissues with large amounts of glucose, which acts as a form of natural antifreeze to limit the formation of ice crystals. Their hearts, brains, and other organs are put into a form of stasis, their eyes turn white as the lenses freeze, and up to 70% of their total body water becomes extracellular ice. They can remain in this suspended state for 8 months, until spring arrives and the wood frogs defrost and hop away. Are you aware of this remarkable ability of wood frogs to freeze their bodies during the bitter cold winter, then come alive again in Spring?
