Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.The plica semilunaris is a small fold of tissue on the inside corner of the eye. It is the vestigial remnant of the nictitating membrane, an organ that is fully functional in some other species of mammals.
