A "Spider Eye" refers to the compound eyes found in many species of spiders. These eyes are made up of multiple lenses, allowing spiders to detect movement and light from various angles. While most spiders have eight eyes, the number can vary, and their arrangement can differ between species. Spider eyes are not designed for detailed vision but are excellent for spotting predators and prey. Some spiders, like jumping spiders, have particularly advanced vision, enabling them to judge distances accurately and make precise jumps. This adaptation is crucial for their hunting strategies.
