Welcome back to the Britt’s Beach Shell Encyclopedia, where we discover the beautiful, unusual, and sometimes surprising seashells found along our beaches and oceans. 🐚🌊
For Shell Encyclopedia #17, we’re featuring a shell with one of the most recognizable spirals on the beach: the Shark Eye Moon Snail (Neverita duplicata).
The Shark Eye Moon Snail gets its memorable name from the dark spiral near the center of its smooth, rounded shell. When viewed from the top, the spiral can look remarkably like an eye staring back at you.
Colors vary from creamy white and tan to shades of gray and brown, often with subtle bands or variations that make every shell slightly different.
Its beautifully simple shape makes the Shark Eye a fun shell to discover while shelling and beachcombing, especially when that unmistakable spiral appears among the sand.
Shark Eye Moon Snails live along the western Atlantic coast and throughout the Gulf of Mexico, making them a species beachcombers may encounter along Florida's coastline.
They prefer sandy environments and spend much of their lives beneath the surface of the sand.
That means you could be walking across a beach with moon snails hiding beneath your feet without ever realizing they're there!
Take one look at the shell from above and the name starts to make sense.
The shell's low, rounded shape curls inward toward a darker central spiral. That contrasting spiral creates the appearance of an eye or pupil, which inspired the common name “Shark Eye.”
It's one of those natural patterns that makes you appreciate just how incredible seashell designs can be.
The Shark Eye Moon Snail may look peaceful, but it's actually a predatory marine snail.
Moon snails hunt other mollusks, including clams. They can drill remarkably neat, round holes into their prey's shells before feeding.
If you've ever found a clam shell on the beach with an almost perfectly circular hole drilled through it, a moon snail could have been responsible.
Suddenly that cute little “shark eye” seems a little more appropriate. 👀
Part of the Britt’s Beach Shell Encyclopedia is learning to enjoy seashells while respecting the animals and ecosystems they come from.
IDENTIFY 🔎
Look for a smooth, rounded shell with a low spiral and distinctive darker “eye” near its center.
APPRECIATE ♡
Take a moment to notice the colors, bands, curves, and spiral. Even shells belonging to the same species can have beautiful natural differences.
PROTECT 🐚
Always check a shell carefully before taking it from the beach. If there's a living snail or another marine animal inside, gently return it to where you found it.
Those perfectly round holes you sometimes discover in clam shells aren't necessarily caused by damage after the shell washed ashore. They can be evidence of a moon snail's meal!
Nature can be beautiful and a little savage. 🌊
From its mesmerizing eye-like spiral to the predator that once lived inside it, the Shark Eye Moon Snail is another reminder that the shells scattered along our beaches have entire stories behind them.
The next time you're walking along the Florida coast with your eyes on the sand, keep watch for that unmistakable spiral looking back at you.

There’s something magical about discovering a shell that looks like it was decorated by nature itself. The Alphabet Cone (Conus spurius) is one of those unforgettable finds, admired for its intricate brown markings that resemble ancient letters or symbols written across a smooth ivory shell. Whether you're an avid beachcomber, shell collector, or simply love the ocean, this remarkable cone shell is one worth learning about.
The Alphabet Cone is a marine snail belonging to the cone shell family. Its glossy, cone-shaped shell is covered with distinctive brown markings that inspired its common name. Every shell has a unique pattern, making each one a miniature work of natural art.
Alphabet Cones are found throughout the western Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. Along Florida's Gulf Coast, they're occasionally discovered after storms or periods of rough surf when deeper water shells are washed onto the beach.
If you're shelling along Florida's beautiful beaches, keep an eye out around:
While they aren't found as frequently as shells like the Lettered Olive, discovering one is always an exciting surprise.
Most Alphabet Cone shells measure between 1½ and 2½ inches long, though exceptionally large specimens can grow slightly larger. Their smooth surface and symmetrical shape make them favorites among collectors.
Living cone snails are predatory marine animals that use a specialized harpoon-like tooth called a radula to capture small prey. While the Alphabet Cone is far less dangerous than some tropical cone snail species, it's always best to admire any living cone snail without handling it.
The best opportunities to find Alphabet Cone shells are after tropical systems, cold fronts, or strong onshore winds. Walk the high tide line early in the morning and carefully check shell piles where heavier shells tend to collect.
The Alphabet Cone perfectly captures why shelling is so rewarding. Every shell tells a story, and this one almost looks as though the ocean wrote one itself. Its elegant markings, polished finish, and distinctive shape make it one of the most beautiful shells found in the Gulf of Mexico and Atlantic waters.
At Britt's Beach, shells like the Alphabet Cone inspire our passion for the ocean and the handcrafted beach jewelry we create. Every beach walk offers the possibility of discovering another incredible treasure waiting to be appreciated.
The ocean is full of fascinating shells, and we're just getting started. Follow along as we continue exploring the incredible treasures found along Florida's Gulf Coast and beaches around the world.
Every Shell Has a Story. 🌊🐚
If you've ever walked a quiet Gulf Coast beach after a passing storm, you know the excitement of spotting an unusual shell peeking through the sand. One of the most beautiful treasures you may discover is the Scotch Bonnet (Semicassis granulata), a shell admired for its elegant shape and distinctive checkerboard pattern.
Although it's best known as the official state shell of North Carolina, the Scotch Bonnet also inhabits the warm waters of the Gulf of Mexico, Florida's Atlantic coast, and throughout the Caribbean. While not as commonly found as fighting conchs or lightning whelks, beachcombers know that finding one is a special reward.
The Scotch Bonnet is easy to recognize once you know what to look for.
Characteristics include:
Its beautiful pattern reminded early naturalists of the traditional tartan bonnet worn in Scotland, giving this shell its memorable common name.
Scotch Bonnets live on sandy and muddy bottoms in relatively shallow coastal waters.
Their range includes:
Empty shells occasionally wash ashore after strong tides or tropical storms, making them an exciting find for shell collectors along Florida's beaches.
The Scotch Bonnet belongs to the helmet shell family (Cassidae), a group of marine snails known for their sturdy shells and fascinating feeding habits.
Unlike many other gastropods, Scotch Bonnets prey primarily on sea urchins and sand dollars, using their specialized radula—a ribbon-like tongue covered with tiny teeth—to drill and feed on their prey. This natural behavior helps maintain healthy marine ecosystems by keeping populations of certain echinoderms in balance.
Collectors have admired Scotch Bonnets for generations because every shell has its own unique pattern. Some display bold, chocolate-colored squares, while others feature delicate pastel markings that almost glow against the creamy shell.
A well-preserved Scotch Bonnet with intact color and minimal wear is considered one of the more desirable finds along the southeastern coastline.
If you're hoping to add a Scotch Bonnet to your collection:
Leaving live shells where you find them helps protect our coastal ecosystems for future generations.
At Britt's Beach, every shell tells a story of the ocean. Whether you're searching Florida's Gulf Coast or exploring beaches around the world, discoveries like the Scotch Bonnet remind us why beachcombing is so rewarding. Every tide brings the possibility of finding something truly unforgettable.
As always, admire responsibly, collect thoughtfully, and help preserve the beaches we all love.
Every Shell Has a Story.
There are few seashells more iconic than the Horse Conch. Towering over nearly every other shell found along the Gulf Coast, this magnificent marine snail is famous for its brilliant orange opening, impressive size, and unmistakable spiral silhouette. For beachcombers across Florida, spotting a Horse Conch is an unforgettable experience.
As a Florida-based beach jewelry company, this shell holds a special place in our hearts at Britt's Beach. Every walk along Florida's Gulf Coast reminds us that some of the world's most extraordinary treasures can be found right here at home. The Horse Conch perfectly represents the beauty, strength, and coastal heritage that inspire every handcrafted piece we create.
Triplofusus giganteus
The Horse Conch belongs to the family Fasciolariidae, commonly known as tulip and spindle snails. It is the largest gastropod native to the Atlantic Ocean and one of North America's most impressive marine mollusks.
The Horse Conch was officially designated as the State Shell of Florida in 1969, making it one of Florida's most recognizable natural symbols.
Its selection celebrates the state's rich marine biodiversity and highlights the incredible wildlife found along Florida's thousands of miles of coastline. For generations, the Horse Conch has represented the spirit of Florida's beaches, inspiring collectors, artists, and ocean lovers alike.
For Britt's Beach, this recognition makes the Horse Conch especially meaningful. Our jewelry is handcrafted along Florida's beautiful Gulf Coast, where every shell tells the story of the waters that inspire our designs.
Horse Conchs inhabit warm coastal waters throughout the western Atlantic and Gulf of America.
Their range includes:
Although empty shells occasionally wash ashore after storms, living Horse Conchs are most often found crawling across sandy bottoms, seagrass flats, oyster reefs, and shallow coastal waters.
The Horse Conch earns its name honestly.
Adult shells commonly reach:
This makes the Horse Conch the largest marine snail native to the Atlantic Ocean and one of the largest gastropods in the world.
Despite their enormous shells, the animals inside remain surprisingly agile predators.
One of the Horse Conch's most recognizable features is its vibrant orange body.
Unlike many marine snails with muted colors, the Horse Conch displays brilliant shades of orange to coral-red that contrast beautifully with its tan, cream, and peach-colored shell. This striking coloration makes it one of Florida's most photogenic marine animals.
Horse Conchs are powerful carnivores.
Their diet includes:
Using a muscular foot and specialized feeding organ called a radula, they overpower prey that would seem surprisingly large for a snail.
Finding a complete Horse Conch shell on the beach is a rare and exciting discovery.
The best opportunities often come after tropical storms, strong winter cold fronts, or periods of unusually low tides. Because these shells are highly prized by collectors, they don't stay on the beach for long.
If you discover a living Horse Conch, admire it where it belongs. Florida's marine life is part of what makes our beaches so extraordinary, and protecting these incredible animals ensures future generations can experience them too.
At Britt's Beach, Florida isn't just where we're located—it's who we are.
Every shell, sea glass treasure, and handcrafted piece of jewelry begins with a love for Florida's coastline and the unforgettable moments spent searching its shores. The Horse Conch reminds us why we fell in love with beachcombing in the first place: every tide has the potential to reveal something extraordinary.
Whether you're exploring the white sands of the Emerald Coast, walking the shell-rich beaches of Sanibel, or searching hidden stretches of Florida's Gulf Coast, the Horse Conch stands as a symbol of the incredible beauty waiting to be discovered.
Because at Britt's Beach, the artist is Brittany—and so is the ocean.

Every Shell Has a Story.
Few seashells are as instantly recognizable as the Lightning Whelk. With its long graceful siphonal canal, sculpted whorls, and warm shades of cream, tan, and cinnamon, this remarkable shell has fascinated beachcombers, collectors, and marine enthusiasts for centuries. Unlike most sea snails, the Lightning Whelk grows in a left-handed (sinistral) spiral, making it one of the ocean's most unique natural creations.
The Lightning Whelk is also deeply woven into coastal history. Native American cultures along the Gulf Coast prized these shells for ceremonial objects, tools, and ornaments long before modern collectors admired them on the beach.
Sinistrofulgur perversum
The name Sinistrofulgur literally refers to its left-handed coiling, while perversum reflects its unusual spiral direction compared to most marine gastropods.
Lightning Whelks are native to the western Atlantic Ocean and Gulf of America, where they inhabit sandy bottoms and shallow coastal waters.
They are commonly found along:
Most shells discovered by beachcombers have been carried ashore by strong tides, tropical storms, or winter cold fronts.
One of the Lightning Whelk's greatest distinctions is that it is the official State Shell of Texas.
Adopted as the Texas State Shell in 1987, the Lightning Whelk represents the rich coastal heritage of the Lone Star State and is one of the most recognizable marine symbols found along Texas beaches. It has become a favorite among shell collectors visiting places like South Padre Island, Galveston, Port Aransas, and Mustang Island.
Perhaps the most fascinating feature of the Lightning Whelk is its left-handed opening.
Nearly all marine snail shells coil to the right (dextral), but the Lightning Whelk opens on the left side when the pointed tip is facing upward. This uncommon characteristic immediately sets it apart from nearly every other shell beachcombers encounter.
Despite its beautiful appearance, the Lightning Whelk is an active predator.
Its diet includes:
Using a specialized feeding organ called a radula, the Lightning Whelk drills or pries open its prey before feeding.
After strong storms or unusually low tides, keep an eye on shell lines along Gulf Coast beaches. Empty Lightning Whelk shells are often found partially buried in the sand, with only their pointed spire or long canal visible. Finding a large, unbroken specimen is considered a prize by many shell collectors.
As always, admire living animals in their natural habitat and only collect shells that are completely vacant.
At Britt's Beach, every shell reminds us that the ocean creates art more beautifully than we ever could. While Lightning Whelks are often too large for wearable jewelry, their elegant form and warm coastal colors serve as endless inspiration for handcrafted beach jewelry, ocean-inspired collections, and the adventures that lead us to discover these incredible treasures.
Whether you're beachcombing along Florida's Emerald Coast or searching the shores of Texas, every shell has a story waiting to be discovered.
