Habitat

Sandy intertidal and subtidal zones of marine environments.

When to Find It

Ecological Role

The living snails are predators that help regulate bivalve populations by drilling holes in their shells. Empty shells provide homes for hermit crabs.

Easily Confused With

Periwinkles (generally smaller and more pointed) or Nerites (often more colorful with different apertures).

Observation Tips

Look for these along the high-tide line on sandy beaches. Check inside to ensure it is vacant and not currently housing a hermit crab before collecting.

Interesting Facts

Moon snails use a specialized organ called a radula to drill perfectly circular holes into the shells of clams and other mollusks to eat them.
