In snails, manipulating the orientation of cells in the early embryo alters the left–right asymmetry of the shell and body. These findings refine the search for the symmetry-breaking event in this and ...

I made use of the known dates of reclamation (and of afforestations) in the IJsselmeerpolders in The Netherlands to assess evolutionary adaptation in Cepaea nemoralis. At 12 localities (three in each ...

Mollusks add daily to the margins of their shells, producing intricate patterns prized by beachcombers. Though this seems complex, the process can actually be explained by a simple network of nerve ...

Taking a trick from birds and butterflies, a mollusk shines blue using intricate structures that allow selective reflection of light. But unlike other animals, the blue-rayed limpet, a snail that ...

As well as Neanderthal remains, the research team has stumbled across large quantities of cultural debris, including a tiny snail shell plaque that was made by the first modern people in the region.
