We therefore expect periwinkle establishment in British Columbia to be limited to areas with low predator density, as is seen in its field distribution to date. "Evolutionary advantage of the common periwinkle: Adding one heavy-metal-binding domain in a cysteine-rich protein may be one of the sea snail's adaptations to metal stress." Protein is also important in the growth and development of the body. Its shell is much harder and stronger than that of an ordinary snail. A special kind of small sulfur-rich proteins, the metallothioneins, have an extraordinarily large capability for binding heavy metals.
