What is a "wood frog"?

A wood frog is a small amphibian known for its remarkable adaptations to survive in cold environments. It is found across North America and has a distinct brown or reddish coloration. What sets the wood frog apart is its ability to freeze solid during the winter months and then thaw out and resume normal activities in the spring. This incredible ability is achieved through a process called cryopreservation, where the frog's body produces special chemicals that protect its organs and tissues from freezing damage. The wood frog's resilience and adaptability make it a fascinating species and a true survivor in harsh climates.
