Known as a univalve shell, the shell of gastropods like snails, periwinkles, conches, whelks, limpets, and abalones is usually coiled or spiraled. This exoskeleton protects them from predators and defends land snails against the sun and drying out. Most gastropod species have shells that coil clockwise. Rarely, a member of one of these species produces a shell that coils in the opposite direction. Such shells are prized by collectors. What has the largest shell of any living gastropod?
