## Quick answer

Hermit crabs are crustaceans that protect their soft, spiraled abdomens by living inside empty snail shells. As they grow, they leave their old shell and move into a larger one, sometimes lining up to swap shells in sequence. Found on shorelines and seabeds worldwide, many species live 10 to 30 years, and they are popular, low-cost pets.

## Borrowed homes

Unlike true crabs, most hermit crabs have a soft, curled abdomen with no hard shell of its own. To protect it, the crab backs into an empty snail shell and carries it everywhere, gripping the inside with specially shaped rear legs. The shell shields the crab from predators and from drying out.
