Backyard and Beyond

Three different specimens of our old friend Cepaea nemoralis.The snail’s “foot,” which gave rise to the name for this whole class of Molluscs, Gastropoda, which means simply stomach-foot (and is anatomically incorrect; the stomach is in the portion of the animal that is inside the shell).Just a size comparison with some other snails found during this clean up. The mm ruler looks bent because the macro lens distorts at the edges, either that or the omphalos of the shells draws gravity in like a black hole.Unknown species on the left;Discus rotundatus on the right.
