Butterflies have four life stages. These stages have entirely different functions: caterpillars feed and grow, chrysalids metamorphose, adults reproduce.

When insects, spiders, crabs, and snakes grow too large, they must shed their outer covering and make a new one to grow into.

Crabs are found in all zones of the ocean and a few on land. They have 10 legs and a hard exoskeleton. There are about 5,000 species.
