title: Mollusc evolution: seven shells on the sea shore.
abstract: Recent phylogenies unite two seemingly very different groups of mollusc: the Polyplacophora with multiple shells and the shell-less Aplacophora. The finding of seven muscle rows in larvae of both classes suggests that polyplacophoran-like shell rows have been lost in adult Aplacophora.
