I found mollusc shells on the beach yesterday.
Oh nice, which beach did you find the shells on?
Just on a beach in San Diego.
That's neat. Are there usually a lot of mollusc shells there?
Yes, you can find them on land and in the freshwater.
Neat. I don't live close to any bodies of water myself, so I never see that kind of thing!
So you have never lived along the coast?
That's right. I've always lived in a suburban kind of area. A trip to the beach takes a few hours of driving. It must be nice to live close to a beach.

Shells are used decoratively in many ways. They can be pressed into concrete or plaster to make decorative paths, steps or walls and can be used to embellish picture frames, mirrors or other craft items. They can be stacked up and glued together to make ornaments. They
