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 ...

The snail’s shell diameter averages about 22 to 30 millimeters (.87 to 1.18 inches). Each snail’s shell has a unique combination of stripes and colors, so no two are exactly alike. These snails eat ...

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 ...

Symmetry is a feature of many plants, animals and even some molecules -- like water. But that's not the case with snails and their coiled shells. They are chiral -- asymmetrical in such a way that ...

Along parts of the Western Australian coast, large shells sometimes lie half buried in tidal mud. They belong to Syrinx aruanus, known as the Australi.

A pet snail in West Sussex once stunned record keepers with a 27.3cm shell, yet ocean species grow far larger. So which snail truly claims the crown for size?

New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions.
