Seashells of Long Ago

By comparing fossil shells with today's seashells from warm and cold climates, scientists discover what the climate may have been like in different regions millions of years ago.

Snails Grow Larger Shells

Snails take calcium carbonate and other materials from water and food and use it to enlarge their shells. The body part called a mantle builds the new portion of a shell.

Hermit Crabs Find New Homes

When hermit crabs outgrow their shells, they look for a new empty snail shell to take over. If it weren't for snail shells, hermit crabs would have no homes.

Shells Come in Many Colors

Mollusks can turn their shells different colors by eating a variety of colorful food. For example, red seaweed gives some sea animals a red shell.

Adding Protection

Some animals have carrier shells. They attach other shells or shell pieces to their own shells with a kind of glue that they make. The extra shells add protection and camouflage, helping the animals hide from predators.
