Shell Family Hub
Moon Snails: Perfect Spheres of the Intertidal
Round, smooth, and predatory — moon snails leave the neat drill-holes you'll spot on countless shells along the wrack line.
Moon snails (family Naticidae) are the burrowing predators responsible for many of the countersunk holes you find in cockles, clams, and small bivalves. Their own shells are near-spherical, patterned with delicate coloration, and highly collectible.
This hub links moon-snail identification pages, prey/predator storytelling, and the beaches where whole specimens are most likely to appear.
