Did you know that mollusks don't see the patterns on their shells, but they sense them? With their spongy coat they envelop the entire shell and "draw" as they enlarge their shell. Who knows, maybe they write so as not to forget something, maybe they are trying to communicate with us.
An essential book for all those adventurous in marine environments, for those who are careful observers and want to discover the past, present and future of our world... just hold a shell to your ear!
