Earthworms do not have eyes in the traditional sense, but they do have light-sensitive cells that allow them to detect changes in light and dark. These cells are located on the skin and are connected to the brain, allowing the earthworm to respond to changes in its environment.
However, earthworms do not have the ability to see shapes, colors, or details in their surroundings. Instead, they rely on their light-sensitive cells to navigate their way through the soil, detect predators, and find food.
In addition to their light-sensitive cells, earthworms also have other sensory structures that allow them to sense their environment, including tactile bristles and olfactory receptors. These structures help the earthworm to locate food, avoid danger, and navigate through its underground environment.
