Yes, we do have eyes Nudibranch do has eyes, usually seen as tiny black dots. It is thought think that all the eyes can do is let the slug know whether it is light or dark, or when a shadow is passing over them. This might be useful if the shadow is made by a fish or something that is coming to eat them.
