What is the lowest temperature an animal can survive in?

Tardigrades are known for their ability to enter states of suspended animation in extreme environments, allowing them to survive in temperatures as low as approximately 1 Kelvin (-459 degrees Fahrenheit). However, it's important to note that this is a state of suspended animation rather than ongoing survival. At such极端ly低temperatures, most biological functions are halted or significantly reduced, bringing the organism close to a state of suspended animation.
