Identify Any Seashell from a Photo
Seashells are easier to identify than most natural objects because shape, surface pattern, and aperture details are usually stable across specimens. Our AI shell identifier compares your photo against the common bivalves and gastropods of the world's coastlines and names the most likely species.

Why identifying seashells matters
Identification matters mainly for two reasons. First, certain species are protected — Queen conch, abalone, and some Olive shells are illegal to take from the beach in many jurisdictions, even if dead. Second, knowing the species opens the door to learning what animal lived there and where in the world that family thrives.
What helps identify seashells
Univalve vs bivalve
Bivalves (clams, scallops, mussels, oysters) have two hinged halves. Gastropods (conchs, snails, cones, augers) are single coiled shells. This first split decides everything that follows.
Spire and aperture
For gastropods, the height of the spire, the shape of the opening, and the number of whorls are diagnostic. Long pointed spires (augers), low rounded (cowries), or flared (conchs) split major families fast.
Surface pattern and texture
Smooth and glossy (cowries, olives), ridged (scallops, cockles), spiked (murex, drupe), or fluted (conchs). The pattern often pins down the species.
Color and original markings
Live shells have distinct color patterns that fade after long beach exposure. A faded shell can still be identified by ghost markings under raking light.
Photo tips for the best identification
- 1Photograph the shell from at least two angles: side profile and aperture (opening).
- 2For bivalves, capture both the outside and inside of one valve.
- 3Place the shell on a plain surface in natural light to preserve color detail.
- 4Include a coin or ruler for scale — many similar-looking species are separated by size class.
Frequently asked questions
Is it legal to take seashells from the beach?
Depends on the location and species. Most empty shells from public beaches in the US are fine to collect in small quantities, but live shelling is regulated everywhere and some species (Queen conch in Florida, abalone in California) are protected even when dead. Check local rules before collecting.
Can the AI tell live from dead?
From a photo, the AI can usually tell whether the shell is fresh (color saturated, periostracum intact, animal possibly still inside) versus long-dead (faded, encrusted, eroded). For live shells, leave them on the beach.
What if the shell is broken?
Even fragments are often identifiable — a piece of a conch spire, half a scallop, or the apex of an auger usually contains enough diagnostic features. Photograph the largest intact section.
