Beachcombing and shell collecting are some of the most popular beach pastimes. But have you ever stopped to think about where that seashell came from? For this lecture, we will discuss what exactly makes those seashells, how those seashells get made, and meet the living version of them! This lecture is co-sponsored by the Avalon Environmental Commission and the Avalon Free Public Library and is being held at Surfside Park, 30th Street and the beach next to Community Hall.
