Backyard and Beyond

Some time ago, I found a couple of queen conch shells, Strombus gigas, at Dead Horse Bay. Needless to say, this is not this tropical species typical habitat. But the landfill at Dead Horse Bay turns up the strangest things sometimes. Perhaps these were somebody’s souvenirs once. Anyway, a ruthless recycler, I put the shells in the Back 40 for ornamental purposes. The other day, I turned over the one that sits on the concrete. Two — perhaps three — species of snails were attached.Cepaea nemoralis.Discus rotundatus.Tiny: no more than two millimeters across. Wondering if these — there was at least one more — are young versions of the above Discus? UPDATE: wonders never cease; this is actually probably V. costata, as discussed in the next post.
