A troglobite is a type of organism that has adapted to live exclusively in dark, underground environments, such as caves. These creatures have evolved unique features, such as loss of eyesight and pigmentation, to thrive in their lightless habitats. Common examples of troglobites include certain species of cave fish, insects, and amphibians. Troglobites are important for studying ecosystems and biodiversity, as they provide insights into how life can adapt to extreme conditions. Their specialized adaptations make them vulnerable to environmental changes, highlighting the need for conservation efforts in their habitats.
