I didn't know this, but STARFISH HAVE EYES EVERYONE.
This means every time I've touched a starfish, I probably touched them in the eye.
IN THE EYE.
National Geographic says that starfish have an eye at the end of each leg. I have definitely touched one.
Once I get over that squick, I'll probably think it's really cool how an animal without a recognizable brain can see.
PS: I was going to google "starfish eye" to illustrate this post and then I was like NO BAD IDEA.
