Shell Identification: A Complete Beachcomber's Reference
The single starting point for identifying anything you've picked up on the beach — with links into species pages, look-alike comparisons, and regional guides.
Identifying shells is a slow craft. Shape and coil direction come first, then texture, color, and hinge structure. This hub pulls together every identification guide we publish and connects them to the canonical species pages in the reference.
Start with the shape families you're seeing on your beach walks, then drill into the individual species pages linked below.
