Hello, I'm an expert in marine biology. Let's dive into the fascinating world of sea stars, commonly known as starfish.
Sea stars do have a simple light-sensitive structure called an eyespot. These are not complex eyes like those found in humans or other higher animals. Instead, they are pigment spots that can detect light and the direction it's coming from. This helps the sea star to navigate its underwater environment and avoid predators or find a suitable place to rest.
Eyespots are located at the end of each of the sea star's arms. While they cannot form images like human eyes, they are sensitive to changes in light intensity and can help the sea star regulate its position relative to the sun or other light sources.
In summary, while sea stars do possess a form of visual organ, it is quite different from the eyes of more advanced organisms.

Scientists say that starfish, like this blue starfish, use their eyes to stay close to home. Update, February 7, 2018: This story has been updated with information on the 2018 study on deep-sea starfish in the Arctic. Starfish have eyes��one on the end of each of their arms��but what they do with them was anyone's guess.
