What adaptations do animals living in caves typically exhibit?

Animals living in caves tend to exhibit adaptations that enhance their survival in dark and often resource-scarce environments. One of the most common adaptations is the loss of sight, which can occur because vision becomes less useful in complete darkness. Instead of relying on sight, these organisms develop enhanced other senses, such as heightened sensitivity to sound, smell, or touch. This allows them to navigate their surroundings, locate food, and identify potential predators effectively.

The other options do not accurately represent the adaptations of cave-dwelling animals. Bright colors and large bodies are not advantageous in dark environments; in fact, many cave animals are often colorless or pale due to the absence of light. The ability to fly in dark areas is not a typical adaptation for cave-dwelling species; instead, they have to maneuver in confined spaces without the need for flight. Additionally, thick fur for insulation would be less important in the relatively stable temperatures of caves than in other environments. Overall, the loss of sight and the enhancement of other senses are crucial adaptations that help these animals thrive in their unique habitats.
