Blind beetles are a group of insects that have lost their eyesight due to living in dark environments, such as caves. These adaptations help them survive in places where light is scarce, allowing them to focus on other senses like touch and smell to navigate and find food. Many species of blind beetles belong to the family Carabidae, commonly known as ground beetles. They often have elongated bodies and are usually pale in color, which helps them blend into their surroundings. Their unique adaptations make them fascinating subjects for studying evolution and the effects of environmental changes on species.
