This beautifully illustrated book, designed for preschool and kindergarten, explains different kinds of shells and the creatures that inhabit them. The shells are compared to the shelter occupied by people and by other animals. We learn that some shells do grow larger along with certain animals while other animals must shed their out-grown shell in favor of a new one. Many shells are beautifully depicted and identified and the story-format of the text is very easy and interesting for young children to follow.
