Hi, Mr. Nature here, with a very unusual little fish that lots of people have never heard of: Anableps, aka the four-eyed fish. I met this little creature in a Mark Trail comic in the Sunday paper when I was a small boy, and never forgot it. Not that I was ever going to catch one in my net in Tommy’s Pond. The four-eyed fish lives in ponds and streams in Central and South America.
Does it really have four eyes? Well, just about! Its two eyes are each divided into two different parts so that the fish can see above and below the surface of the water at the same time–something I have tried to do with a swim mask on, but no dice. So this otherwise unremarkable fish has a highly specialized eye, unique to its kind.
This is God’s stuff, marvelous to behold. None of this pfud about the fish’s eye “evolving” from one form to another–it’d be pretty useless at the half-way point; and if a chance mutation resulted in a couple of four-eyed fish hatching out of the eggs of an ordinary two-eyed fish, that’s not much to build a viable species on.
I’m Mr. Nature, and I can end my sentence with a preposition if I want to.
