Troglobites are specialized organisms that live exclusively in dark, underground environments, such as caves. These creatures have adapted to their unique habitats, often exhibiting features like loss of pigmentation and eyesight. Common examples of troglobites include certain species of cave fish, insects, and amphibians. These organisms play a crucial role in cave ecosystems, contributing to nutrient cycling and serving as food for other wildlife. Troglobites are often studied in the field of biospeleology, which focuses on the biology of cave-dwelling organisms and their adaptations to extreme environments.
