Why Are There So Many Shells On Sanibel Island?


Sanibel Island is known as the shelling capital of the world, and for good reason. Sanibel Island is surrounded by an underwater shelf, and the island’s unusual east-west facing orientation along the coast of Florida creates a perfect dustpan for shells being pulled in by currents in the Gulf of Mexico. This abundance of tiny treasures has given Sanibel Island its claim to fame, causing many visitors to assume the position of the “Sanibel Stoop” as they bend at the waist looking for shells along sandy stretches. Be on the lookout for the Sanibel Six!


All About Shelling On Sanibel Island Like A Pro


If you’re serious about the pursuit and all about shells on Sanibel Island, you need the right equipment.

STEP 1

Arm yourself with sunblock, a hat, a shelling sifter or scoop, a bucket or bag, and a strong back. The activity is addicting and you may find yourself doing the “Sanibel Stoop” for hours. Also, a pair of water shoes may be a good suggestion as some beaches are covered with tiny, sharp shells.

STEP 2

Look for banks of shells as you walk along the beach. Hundreds of beautiful, tiny shells can be found in these areas.

STEP 3

During low tide, go to the edge of the water where the waves stir up the sand as it hits the beach. Dig down into the sand as well. Dip your net in and see what you find.

STEP 4

For a different color scheme, you may want to look higher up on the beach for shells that have been bleached by the sun. These often white-washed specimens can make an unusual collection.


Is “Live Shelling” Prohibited On All Sanibel Island Beaches?


In the late 1980s, worried about the shell population, Sanibel Island petitioned the Florida Marine Fisheries Commission to restrict live shelling.  As a result, the commission passed a special “Sanibel Shelling” rule called the 46-26.  This rule restricted live shell collection to two specimens of any one species per day.

The 46-26 rule was in effect for six years however, enforcement was virtually impossible, and collecting in excess of these limits occurred regularly. So in 1993 Sanibel Island further petitioned the Fisheries Commission to establish a complete ban on live shelling.  This rule included shellfish, sand dollars, starfish, and sea urchins. After a public hearing, the rule was approved and went into effect on January 1, 1995. Thanks to the conservation-minded islanders, who pushed for rule 46-26 we now have beaches with an abundance of shells and sea life just waiting for you.

Keep in mind, no live shells can be taken. Also, don’t take too many shells. Over-shelling can harm the environment. Also, make sure to hang on to any plastic bags you may have brought to hold your new collection. Plastic bags are deadly to sea life.


The Florida & Sanibel Island Sea Shelling Law


The state of Florida and Sanibel Island shelling laws prohibit the collection of any live species within a half-mile of the shore, including urchins, sand dollars and sea stars, pursuant to Florida Department of Environmental Protection Rule 46-26. Violators can face a $500 fine or up to 60 days in jail for a first offense.

Shelling of any kind is prohibited at J.N. “Ding” Darling National Wildlife Refuge.

What Are The Rare Shells Of Sanibel Island?


While each shell found on Sanibel Island is a miracle of nature, die-hard shell enthusiasts can spend a lifetime looking for the elusive Junonia, a shiny, long, brown, and white speckled shell. Find one and you might get your picture in one of the local newspapers.

Other prized samples are the Scotch Bonnet, a ribbed oval, curled buttery-colored gastropod; the Lion’s Paw, coming in various colors and aptly named for its paw-like shape; and the Alphabet Cone, a tapered, banded tan and white patterned shell. Look out for the 3 most desired shells on Sanibel!


What Is The Best Month For Sanibel Island Shelling?


You can find shells all year long but the tourist season from January through April is the busiest on beaches and the best weather. You may have less competition finding shells in the off-season.

Shells also get stirred up during a storm, so hurricane season or after a big tropical storm can also be a good time to go shell-hunting.

The annual Sanibel Shell Festival, the longest-running and largest shell show in the world, takes place in early March so timing a trip to coordinate with attending the event is well worth the planning.


What Is The Best Time Of Day To Look For Shells?


Early morning low tide is the best time for shelling!

While gorgeous shells can be found any time of day, you will have less competition early in the morning, especially an hour before or after low tide. Some shellers say a full moon phase brings in more shells due to higher tides. After a storm is also a great time to look for shells, as they often get swept in by waves. In the winter months with a north wind–although it can be chilly–is another time that may bring in more little surprises.


What Type of Shells Can We Find On Sanibel Island?


Shells come in two categories: bivalves, which have two hinged sides that clamp together to enclose the species; and gastropods, which consist of a single, curled shell with an enclosed chamber. Some common examples of bivalves include scallops, clams, cockles, coquinas, and lion’s paws. Some common examples of gastropods include many varieties of conch, murex, olives and whelks.


CONCH SHELL

This type of shell houses animals in the snail family. This species comes in all shapes, colors and sizes, and their shell is usually conical, spiral and pointed at both ends with an opening along the side.

Common examples include the Horse Conch, with a light tan or brown spiral, bumpy body measuring up to about 20 inches; the commonly found Florida Fighting Conch, measuring up to about 4 ½ inches with a brownish body with about seven tapered spiny swirls coming to a pointy top; and the Crown Conch, measuring up to about 5 ½ inches with a brownish or grayish swirl patterned body with rows of spines. Keep in mind live shelling is prohibited on Sanibel and Captiva, as sometimes this type of shell still holds its resident.

Fun fact, the Horse Conch is the state shell of Florida!

JUNONIA SHELL

An elusive shell which is the golden ticket for Sanibel Island shell-seekers. Measuring up to about 6 inches in length, it has a conical, smooth body with about 5 swirled rows at the top. It is a pretty shell, patterned by white rows spotted with brownish squares. If you find one, send your picture to one of the local papers for publication!

LIGHTNING WHELK SHELL

A commonly found shell comes in many sizes, up to about 15 inches. Usually light tan and creamy white, this pretty shell has a pointed top spiraling toward a shouldered ridge with small knobs. From there, the shell tapers to a slender bottom with a pointy end. These shells often get washed up after a storm.

COCKLE SHELL

The common cockle shell comes in a variety of sizes and colors. Usually only half of this bivalve is found, but occasionally this hinged shell can be found intact. Cockles are “shell-shaped”, with rowed ridges of patterns and colors of pinks, whites, browns, reds and other similar colors. They measure up to around 6 inches. Some examples are the Atlantic Giant Cockle, Painted Egg Cockle and Florida Prickly Cockle.

TULIP SHELL

Tulip shells can be found in shell banks and along breaking surf during low tide. They measure up to about 7 inches and have distinctive, colorful bands of stripes or similar patterns starting at a pointy top and spiraling down in a circular, sloping body to a pointy end. Examples include the Banded Tulip and True Tulip.

SAND DOLLAR

Not technically a shell, the sand dollar is in the sea urchin family. They can mostly be found under water, along the sandy or muddy bottom. They have a five-pointed star pattern surrounded by rounded body. While keeping a live sand dollar is illegal on the islands, occasionally you can find a dried skeleton along the beach, although it is rare to find one intact as they are very fragile.

OLIVE SHELL

This shell species is aptly named, as it looks almost like a long olive. The Lettered Olive measures up to about 2 ½ inches long with a shiny, polished smooth body beginning with a tiny pointed top with about three swirled bands. They are usually tan or brown and white in pattern.
