A one eyed fish? Is it a cataract? All I can tell you is that there is no fish surgeon in the sea. Fascinating. It’s not that he’s got his eye closed and he’s winking at you. Fish do not have eye lids. This is problematic when you want to get some “shut eye.” But then again I’m not sure they sleep. Anyway, it’s an odd observation. Fishes with disabilities, do they have rights?
