When is the best time to search for seashells and where should I look?

 February 1998

The North Carolina coast is a treasure trove for shell collectors. Our estuaries and ocean waters hold more than 1,000 species of mollusks – shell-bearing animals.

Hundreds of miles of sand beaches provide collecting grounds for many species. However, beaches aren’t the only good places for shelling. Sounds, inlets, lagoons and intertidal flats are also home to many mollusks. These areas are rich in food and less subject to the rigors of wave action. They can yield a wide variety of mollusks, ranging from the tiny periwinkles that cling to marsh grasses to the spiral shaped whelks that surface on sand flats at low tide.

Several areas along North Carolina’s coast have been dubbed as the best places to find seashells. Cape Hatteras National Seashore, Ocracoke Island, Cape Lookout National Seashore, Shackleford Banks, Hammocks Beach State Park and inlets near Wrightsville Beach have all earned a reputation among shell collectors.

While tides bring shells to our beaches all year, early spring, particularly after a storm, and early fall, during the height of hurricane season, are prime times for shelling. Winter storms and hurricanes churn the waters, pulling shells from the ocean floor and washing them onshore. When combing beaches after a storm, don’t forget to examine the masses of seaweed for surprises that might be lodged in the wrack.

Tides and timing are also important when searching for shells. An hour before and after low tide, especially during spring tides that occur on new and full moons, are favorable times for collecting.

Although most of the shells found on the shore are empty, each was once home to a living animal. Mollusks make up one of the largest groups in the animal kingdom, second only to insects. Most shells belong to two mollusk classes — gastropods (the largest group) and bivalves. Gastropods have a single shell and are usually spiral or cone shaped, such as snails, whelks and scotch bonnets, the state’s official state shell. Bivalves have two hinged shells, such as clams, oysters and scallops.

A mollusk shell is formed by secretions from the animals’ mantle, a fleshy sac that lines their soft bodies. These secretions mix with calcium  derived from their environment – either the food they eat or the water in which they live – to form a shell. Food, climate, environment and the mollusk’s particular heredity all play a part in making each shell unique.

Most mollusks found in or near North Carolina’s coastal waters are plentiful, but destruction of natural habitats and overfishing have seriously reduced some populations. If a living creature inhabits a shell, enjoy observing it but leave it in its natural habitat undisturbed.
