North Carolina’s State Shell

The Scotch Bonnet

The Scotch Bonnet

In 1965, a shell resembling a traditional Scottish woolen cap or Scotch bonnet, was named the state shell of North Carolina, in part to honor early Scottish settlers. Scotch bonnet shells wash ashore in abundance on North Carolina’s Outer Banks. They are rare elsewhere in the state.

Where are Scotch bonnets found in North Carolina?

The Gulf Stream moves tropical waters close to the North Carolina coast.

Tropical water mollusks, like the Scotch bonnet, can survive cold winter months in the Gulf Stream.

After storms, hundreds of Scotch bonnets may be washed ashore on the Outer banks especially between Cape Hatteras and Cape Lookout due to the close proximity of the Gulf Stream to that section of the coast.

Life Cycle of the Scotch Bonnet

Female Scotch bonnets lay eggs in the spring.

Shell-less free-swimming larvae or veligers hatch from the eggs.

They drift with the ocean currents.

When they begin to form a shell, they settle to the bottom as crawling mollusks.

Scotch bonnets feed on sand dollars.

Scotch bonnets mature in one to six years.

The juvenile shell has a thin, delicate lip.

Mature shells have a thickened, rolled lip.

When a shell washes ashore, its color fades quickly upon exposure to the elements, especially the sun.

The shell is fragile so a complete specimen is always a prized find.

And finding a complete specimen that retains its color is a special treat, even to the seasoned collector

FACT: North Carolina was the first state in the USA to name an Official State Shell. This move was initiated by The North Carolina Shell Club.

A NEW RECORD!

Olese Walton, a long-time member of our shell club years ago, now deceased, collected shells from scallop piles with her daughter, Eloise, a current member of our club.  Eloise brought several shells in for measurement from Olese’s collection for measurement, amoung them the current record for a dead-collected Scotch Bonnet. It measured 107.3 mm and was collected as Calico Scallop by-catch offshore of Beaufort, NC.

Ben Wunderly tells about finding his shell.

A State Size Record for the Scotch Bonnet, Semicassis granulata (Born, 1778) was found at the 2022 North Carolina Shell Club’s Shell Show. It was brought to the show by Benjamin Wunderley, a former State employee working at Bear Island, a part of Hammocks Beach State Park sometime around 1999. He did not know there was an interest in maintaining size records of shells until reading about it on Social Media and brought it to the shell show to be measured. He has now joined the NC Shell Club!
The shell measured in at 91.25 mm.
