Why don't alligators live in cold climates?

Alligators are ectothermic reptiles, meaning they rely on external temperatures to regulate their body heat. In cold climates, they cannot maintain the necessary body temperature for metabolic processes, leading to decreased activity and survival challenges. They typically inhabit warmer, subtropical regions where temperatures remain conducive to their biological needs. Additionally, prolonged exposure to cold can lead to health issues and even death, making such environments unsuitable for their survival.
