A snail with a shell spiraling to the right can’t mate readily with a lefty. So, changes in the single gene that controls shell direction have created new snail species, say researchers. Among the 20 ...

Snail shells coil in response to an lopsided protein gradient across their shell mantles, finds research in BioMed Central's open access journal EvoDevo. In contrast the shell mantle of limpets, whose ...

Learn about snails with a roundup of snail facts. Discover what snails eat, when they get shells, how long they sleep and how fast they move.

Berkeley -- Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.

Snail shells coil in response to a lopsided protein gradient across their shell mantles, finds new research. In contrast the shell mantle of limpets, whose shells do not coil, have a symmetrical ...
