SHELL KEY PRESERVE GUIDE
SHELLING AT SHELL KEY PRESERVE
Why Shell Key Is Known for Shells
Shell Key is an undeveloped barrier island, and barrier islands are natural shell collectors. Waves, currents, and storms carry shells in from the Gulf and sort them along the high-tide line. With no road access, every visitor arrives by water, so the beaches see far less foot traffic than the mainland shore.
What You Might Find
Shells that commonly turn up on Gulf Coast barrier islands like Shell Key include:
-
Lightning whelks, one of the few whelks that spiral left
-
Florida fighting conchs
-
Cockles and ark shells
-
Coquina, small and colorful, often in clusters
-
Cross-barred venus clams
-
Sand dollars, the pale, bleached empty ones
Harder finds include banded tulips, shark's eye moon snails, angel wings, and the occasional Florida horse conch, the state shell and among the largest snail shells in North America. There's a horse conch photo on the Wildlife page.
When to Look
Early morning and low tide tend to turn up the most, because the falling tide leaves fresh shells along the wet sand. The day after rough weather is often the best of all. Midday is hot, and there's no shade on the island.
Live Shell or Empty Shell? How to Tell
Check before you pick anything up.
-
A conch or whelk with a body inside, or a small hard "door" sealing the opening, is alive.
-
A live sand dollar is dark and covered in tiny moving spines. An empty one is pale and bleached.
-
Hermit crabs move into empty shells. If the shell moves, it isn't empty.
Live animals can't be removed from the preserve. If it's alive, kindly set it back in the shallows where you found it.
Shelling Rules at the Preserve
Pinellas County protects all plants and animals in the preserve and prohibits removing live animals, including sand dollars, conchs, and starfish. The county's rules don't spell out empty shells, so check with Pinellas County Parks before taking any home. Many visitors photograph their finds and leave them on the beach. For the full rules, see Conservation and Rules and the county's Shell Key page.
Shelling Responsibly
-
Stay on wet sand and out of the dunes.
-
Keep out of posted nesting areas and the closed central core.
-
Don't dig or turn over large areas of sand.
-
Shuffle your feet in shallow water so you don't step on a ray.
-
Pack out everything you bring.
Planning a Shelling Trip
There are no restrooms, shade, or services on the island, so bring water, sun protection, and water shoes for broken shell edges. Bring a camera too. Reaching the island takes a boat or paddlecraft. See How to Visit for your options. You can also join a guided tour: Island Ferry, the family behind this site, runs small-group Shell Key boat tours, as well as kayak tours, both with time on the island. To identify what you find, see Pinellas County's Beaches & Shells Guide.
