Fibonacci and String(s) Theory? Weekly Photo Challenge – Geometry


I am fascinated by geometric shapes in nature:

Spiral and String Theory:  Whelk Egg Case and Seaweed

I found this Lightening Whelk Egg Case on a South Florida beach last January, following a strong storm. Egg cases of this size are not typically found ashore as the whelk anchors them  in deep water using the smaller end of the chain. While I don’t know if the egg case has a Fibonacci pattern, the lightening whelk’s shell does.

Here the egg case is twisted into a shape. The egg case spirals upon itself if you hold it by one end. I think it resembles a snake.  When I first found this, I didn’t know if it was animal, vegetable or mineral!  Each link in the spiral can hold up to 150 eggs.  As they hatch, the whelks will eat their weaker siblings, then eat their way out of the case.  Albumin and eggs were visible in some of the links, although they are not viable once loosened from their anchors.

Moon and Starfish

It was still dark outside when my alarm sounded this morning. Usually, when on vacation, I don’t use the alarm unless I have a plane to catch. Today, though, I wanted to catch the full moon setting, the low tide, and sunrise, just before 7 am.

The sky was just beginning to lighten when I walked out on the beach, wondering if my fleece jacket would be warm enough. The moon was glowing in the northwestern sky, looking like a giant Japanese lantern hanging over Sanibel. In Colonial America, the January moon was called the Winter Moon; the Cherokees called it the Cold Moon; the Celts, the Quiet Moon; and the English referred to it as the Wolf Moon. On a subtropical beach, just before a warm winter day, only the Celts seemed to have captured this particular January moon.

January Full Moon: Cold, Quiet, Wolf

I turned towards the south and headed towards the shoreline. The tide would still be moving out for another 20 minutes. The shorebirds had positioned themselves at the very edge of the water; the little squeaky sandpipers running when a wave reached back towards the sand; the larger terns merely lifting one webbed foot as if they couldn’t be bothered. Some of the more industrious birds bobbed for fish or cracked open shells. The less energetic ones merely lowered their heads into the surf, as if they had already had their fill at the morning tidepool buffet.

Cockles: Not a Hard Shell to Crack

As I walked gently through the blubbery sand, I looked at all of the creatures left behind by the retreating waves. I don’t know how they survive, or even if. Are the ones that are exposed by the tide the ones who are living their last moments? Or will they be rescued when the tide pushes back towards the beach, the water trying to reclaim its rightful inheritance and dominion over the planet? I am witness to the struggle near my feet: a starfish has left tracks in the sand; a whelk seems destined for someone’s shell collection — why I think would anyone want one of these? how out-of-place would it be sitting on a shelf or in a basket, bereft of sand and salt and the smell of the sea? — when the shell’s inhabitant extends itself out. A quiet wave washes in and removes more sand from beneath the shell. The mollusk continues to show itself. Suddenly I realize that it is righting itself, repositioning in order to burrow further down into the wet sand. I turn it over with my foot to look at it once again, but immediately feel guilty for doing so. I pick it up and loft it towards the sea. You’ll live to swim another day I think, and then wonder, noticing that the beach is beginning to be populated with walkers and bikers, if I said the words aloud. Later, when reading about the sea creatures I photographed, I learned that the word whelk may have come from the Proto-Indo-European root for “turn or revolve”. It is as fitting, I decide, as calling them gastropods, the larger classification of this sea snail. I wonder about that word too, and the very idea of a “stomach-foot”: is it the ultimate in efficient design to have one appendix to capture your prey, to eat and to move?

Turn, Turn, Turn

I didn’t wander too far down the beach before the sun started to rise. I now had more light to shoot, but the bright, rising sun, still low on the horizon brings other photographic challenges. I turned to head the other direction. Although I knew the time of moonset, it surprised me that the moon had retreated so quickly. I see a few more interesting creatures, mostly sea anemones and heart cockles. I click away, happy that the sun is bouncing off of the pearly nacre, in awe of what marvelous mysteries the sea has deposited at my feet this morning.
