Shells

Shells are the homes of small animals called molluscs. The word 'mollusc' means soft, and all molluscs have soft bodies. Molluscs do not have bones. When the mollusc grows, the shell grows, too.

Some shells have two parts, and the mollusc can open and close the shell to catch food from the water. A clam has a shell like this. Someone found the largest clam in the world in Japan in 1956. It was 115 centimetres long and weighed 333 kilograms! There are many different kinds of shells.

Some shells are very beautiful. Some are one colour; some have lines or spots on them. You can find shells in ponds and on the sea-shore all round the world.
