© National Geographic Society + Hermit Crab Surveys the World from a Borrowed Shell A crab in name only, the hermit carries his un armored body in abandoned mollusk shells. This specimen lives in a smooth spider shell known as Lambis lambis. Australian aborigines hang household objects on the long spines (natural size). + Cowrie Spreads a Red Mantle Across Porcelain-white Shell No shells have been so widely used for trade and decoration as the brilliant cowries. Melward's cowrie (left) rests its foot on organ-pipe coral while the breathing tissues creep over its shell. Shy pustulose cowrie hides within its abode (magnified five times).
