The Whys of Whelks
If you've been wandering along the beach this summer collecting shells, you may have wondered at the amazing variety they show. Take whelks, for example: how old are they? Where on the beach do they live? Was their life hard or easy? All these things you can discover by looking at their shells - you may even be able to trace back a whelk to a single beach from the whole coastline of Britain.
