Stranger and Truer than Science Fiction

Sometimes after watching an episode of the Star Trek TV series, I think that the designers of the space aliens' costumes and makeup need to go back to school, so to speak.  Not to a costuming course in drama school.  And not to a makeup academy.  Instead, they need to return to fiction-writing school to give more thought to what an alien that developed on another planet might even be like.

I tend to think this way not after reading an astronomer's analysis of conditions on other planets.  Instead, my thoughts incline this way after seeing pictures or reading about forms of life in the ocean on our very own planet Earth.  Evolution has come up with some "costumes" and "makeup" far beyond the imagination of any science-fiction writer or director.  And the strangest ways of being a living being can be found in our oceans.

Just take the matter of virtually all space aliens on Star Trek having two symmetrical sides, right and left (just as do humans and all other vertebrates).  A simple exception in the ocean to such symmetry are male fiddler crabs, which have a claw on one side of their bodies much larger than the claw on the opposite side.  (Thus the whimsical appellation "fiddler" we have given them.)

Nature had already gone a step even further away from requiring animals to have two sides when the invertebrates previously evolved.  Sea anemones, sponges, and jellyfish are all circular in design.  Imagine a Star Trek director instructing a person in a spherical costume to "face the camera."  Evolution had an even greater imagination when it came up with the starfish's "costume," giving it five arms -- an odd number, of all things.

Another area in which I think science-fiction writers have been outdone by Nature has been in that of eyes.  I have seen a TV space alien made up with one additional eye on its forehead, or even with an extra pair.  (It would take more work to mask over the actor's real eyes and give them a single, centered eye, like the Cyclops in the ancient Greek epic Homer's Odyssey.)

Contrast that prosaic eye-on-forehead thinking with the idea of a whole ring of small eyes around a circular cookie-shaped body.  To make that many-eyed circular costume even stranger, don't space the tiny eyes at even intervals, but place some a little closer together and others a little farther apart.  That is the approach actually taken by the blue-eyed scallop of Australia. Moreover, what a colorful touch in the pinhead eyes being blue!

Now, please don't misunderstand me.  I am not really trying to criticize science-fiction writers.  I do recognize that science fiction is really more about our human societies than it is about what exists on other planets.  (I also recognize the limitation of trying to make an alien costume that allows a person to fit inside.)  My aim is not criticism but amazement.  I am amazed at the immense variety of "costumes" of the beings in our oceans, demonstrating again that life's possibilities are even greater than our own human imaginations.

Do you think we might draw a lesson from the strange variety of species?  Or would that be carrying our imaginations too far?
