The Scotch Bonnet

North Carolina's State Shell

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 bewteen 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 silent auction runs concurrently to the live auction.
Not only is it a great opportunity to support the shell show but a great opportunity to add new shells and/or related treasures to one's collection.
