Ode to the whelk

My favorite shell in Florida is the whelk. Observe, and marvel, at the symmetrical lines of these shells. The sluglike critter that lives in the shell is an artiste, composing his home with perfect spirals, sleek, curving lines...a master of design! As you can see, they come in a variety of colors. I have found several live ones, which are even more gorgeous but of course have to be thrown back in the gulf, which is fine. Respect must be shown to the designer! Still, one does this with a bit of regret; I cut my foot on what turned out to be a gorgeous large live shell, maybe four inches long...about twice as long as the shells pictured.
