The Arnami really do have a kazillion eyelids.  Their amazingly light-sensitive eyes can see deep under the ocean surface.  Normal surface light would blind them if it weren’t for the eyelids.  And yes, all those eyelids closed against the light make their eyes look solid black.  Real freaky the first time you see them.  Or the hundredth.  I’m real glad they wear shades when among other humans.
