Caves support unique ecosystems through their characteristics such as constant temperature, high humidity, darkness, and limited food supply. These conditions create a specialized environment where unique species have adapted to survive, often with distinct behaviors and physical traits. Additionally, caves provide shelter and protection from predators, making them ideal habitats for a variety of organisms ranging from microbes to bats and cave-dwelling insects. The isolation and stability of cave ecosystems contribute to the evolution of species found nowhere else on Earth.
