Are any areas of the earthworms body more sensitive to light than other areas?

Yes, certain areas of an earthworm's body are more sensitive to light than others. Specifically, the clitellum, which is a thicker, glandular section of the body, is more sensitive due to its higher concentration of light-sensitive cells. Earthworms possess photoreceptors primarily in their skin, allowing them to detect light and avoid exposure, which helps them stay underground and protected from predators. Overall, their ability to sense light is more pronounced in specific regions, aiding in their survival.
