Along the coastlines of the world, a great variety of shells can be found. Seashells are made by the animals that live inside them and all shells grow steadily outward. Shells are among the most remarkable designs found in nature. Examples are the chambered nautilus, the sundial shell, and the triton shell. Shells are usually perceived as feminine; a symbol of birth, good fortune, and resurrection. Bivalved molluscs represent the womb and fertility.
