Question: What animal can survive being frozen solid and then thawed back to life?
Answer: The wood frog. Native to northern North America, the wood frog can survive being frozen solid for months during winter, with its heart stopped and up to two-thirds of its body water turned to ice. It lives thanks to natural “antifreeze” chemicals like glucose that protect its cells. When temperatures rise, the frog thaws out, its organs restart, and it resumes normal life. Researchers have documented this process in detail, calling it one of the most extreme survival strategies in the animal kingdom.
