In my lifetime, I undergoe an unusual transformation in structure. When my egg hatches, like most other fish, I have an eye on each side of my head. After a few days, I begin to lean to one side and the eye on that side migrates to the side with the other eye. In this way, the side that has both eyes becomes the top of me. I become a fish that lives at the bottom, with the color of the eyeless side fading, and becoming the bottom of me. Cause that's just how I sole.
