As to why cave-dwelling fishes have eyes, even though these eyes have no function. Introduction: Vestigial structures or vestigial organs are those structures, which serve little or no function at all in an organism. These vestigial structures are usually homologous to body parts in other organisms, where these structures still play a functional role. For example, the human coccyx (tailbone) is a vestigial remnant of a tail, which suggests that humans share a common ancestry with other vertebrates having tails.
