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.

Seashell identification comes down to whether the shell is a single coiled gastropod or a two-part bivalve, then its shape, size, ridges, and color pattern. A photo of both the outside and the opening usually names the mollusk. Knowing the species tells you the animal, its habitat, and whether your beach find is common or a collector's prize.
Below are the kinds of seashells people most often find along the shore. Scan yours to identify the species and the waters it came from.
Common types of seashells
A quick reference to the ones people ask about most. Not sure which you have? Snap a photo above and let the AI name it.
Scallops and clams
Fan-ribbed scallops and smooth clams are bivalves, usually found as a single hinged half on the sand.
Whelks and conchs
Large spiral gastropods with a flared opening. Among the most prized and recognizable beach finds.
Moon snails and periwinkles
Rounded and small coiled snail shells, extremely common on many shorelines.
Cowries
Glossy, smooth, egg-shaped shells with a toothed slit underneath. Historically traded as money.
Olive and cone shells
Sleek, cylindrical, and cone-shaped gastropods. Beautiful, though some living cone snails are venomous.
Sand dollars
Flattened, star-patterned tests of burrowing urchins. Fragile and bleached white once washed ashore.
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.
Is the shell empty, or still someone's home?
Before you pocket a shell, check that nothing lives inside. A hermit crab may be using it, or the original mollusk may still be present, especially in heavier, fresh-looking shells. Many beaches and parks also prohibit collecting live shells or any shells at all. Take a photo to identify it, peek inside, and leave occupied shells where they are.
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.
