#15 – Plica Semilunaris
If you ever paid close attention to your eyes, you couldn’t help it but notice that weird pinkish thing in the corner of your inner eyelid. Well, that weird little pinkish thing actually has a name and it is plica semilunaris. Now, these weird body parts don’t have any actual function.
They would act as our third eyelid if they were more developed. Now, this brings us to something scary. If you know, reptiles and birds have the third eyelid, and we have a third eyelid remnant, does that mean we are part reptiles or what?
