Cave Community (1960)

The film discusses the unique ecosystem of caves, highlighting the adaptations of organisms that thrive in darkness. It emphasizes the constant conditions found in caves, such as temperature and humidity, and how isolation leads to speciation among cave-dwelling species. The role of surface organisms, like bats, in providing energy through food brought into caves is also explored. The film examines the evolutionary traits of cave species, such as loss of pigment and eyesight, and how these adaptations are beneficial in a cave environment. Additionally, it discusses the food web within caves and the ecological interactions that occur in this lightless biome.
