Nature is a splendid thing. It’s everywhere and full of surprises just waiting to jump out at you. These transparent animals (including fish, amphibians and butterflies) are a wonder to behold.
The species that each one falls under just happens to possess transparent skin (or whatever covers their insides). They are beautiful to look at (most of the time, I just don’t want to look at fish brains) whenever you get the opportunity to really admire them.
I would think that with transparency making its rounds (as it has been in fashion) that these Earth inhabitants might be a little upset that someone stole their entire image.
