Spirals in Time: The Secret Life and Curious Afterlife of Seashells (Bloomsbury Sigma)

Spirals in Time: The Secret Life and Curious Afterlife of Seashells (Bloomsbury Sigma) - Helen Scales Interesting and nicely written book about the critters that make and live in shells, as well as what happens to shells after the inhabitant is no longer there. Not terribly detailed, but I read about creatures I've never heard about before (e.g. an octopus that makes its own shell and sea-silk), so this is a bonus.
