Cave-dwelling species, also known as troglobites, are organisms that have adapted to live in the dark, underground environments of caves. These species often exhibit unique physical traits, such as reduced eyesight and pigmentation, due to their long-term isolation from sunlight. Common examples include certain types of fish, insects, and amphibians. These species rely on specialized adaptations to survive in their nutrient-scarce habitats. They often feed on organic matter that washes into caves, such as dead leaves or other decaying organisms. Some cave-dwelling species have developed unique behaviors and reproductive strategies to thrive in these challenging environments.
