10 Animals That Can Literally Bring Themselves Back to Life

8. Wood Frogs: The Frozen Survivors

Wood frogs, native to North America, have a remarkable ability to survive freezing temperatures by entering a state of suspended animation. During winter, these frogs allow their bodies to freeze, with ice forming in their tissues and organs. Despite this, they can revive in spring, emerging unharmed from their frozen state. This incredible adaptation is made possible by producing cryoprotectants, substances that prevent ice formation within cells, and regulating metabolic processes to minimize damage. Scientists are studying wood frogs to understand the mechanisms that allow them to survive freezing, with potential applications in cryopreservation and organ transplantation.
