As with anything in biology, nothing really makes sense except in the light of evolution. The Mola's no exception. They appeared shortly after the dinosaurs disappeared, 65 million years ago, at a time when whales still had legs, and they come from a rebellious little puffer fish faction -- oblige me a little Kipling-esque storytelling here. Of course evolution is somewhat random, and you know, about 55 million years ago there was this rebellious little puffer fish faction that said, oh, the heck with the coral reefs -- we're going to head to the high seas. And lots of generations, lots of tweaking and torquing, and we turn our puffer into the Mola. You know, if you give Mother Nature enough time, that is what she will produce.
