Shells on Anna Maria Island beaches
Every evening we walk several blocks across Anna Maria Island to the Gulf Beach, where we walk along the water’s edge as the sun approaches the horizon. It’s always interesting to notice what kinds of shells are on the beach at certain times. There are some “regulars,” which are almost always there. And there are some very unusual ones that show up only every once in awhile. But even the unusual ones tend to come in groups. In other words, if there is one, there are many. This happened one evening several years ago when there were beautiful shark’s eyes suddenly on the beach in large numbers.
The shells that usually wash ashore on the beaches of Anna Maria Island include spiny jewelboxes, which are white with spikes protruding. They look like bivalves, but are, in fact gastropods. Another fairly common gastropod shell is the lettered olive, which usually measures almost 2 inches long. We also come across Florida augers quite often, which are small cone-shaped shells.
A wide variety of bivalve shells is also seen at all times. One of the most interesting and charming is the little coquina, which comes in a wide range of pastels and earth tones. There is nothing more enchanting than seeing the live creatures in tidal pools, where they move with the inflow and outflow of the water. Little cat’s paws or kitten’s paws, range in color from white to black to orange. Jingles are translucent shells that come in these same three colors. About the size of a quarter, these round shells look like they’re made of mica.
There are several bivalves with remarkable patterns on them. Although it’s not unusual to see these shells, it is unusual to find one that is not worn. The sunray Venus may be the most beautiful of these shells, with a pattern that really does give the impression of sunrays. Both calico clams and calico scallops are quite common, too. The buttercup has an appealing smooth round shape, and is the color of butter. Less beautiful but more remarkable is the turkey wing, with one very straight edge and an otherwise roughly shaped surface, striped with brown.
