Beach Finds That Aren't Shells

The finds beyond shells

Once you stop looking only for shells, the beach opens up. The keyhole sand dollar is our local one, a flat disc with five neat slots punched through it. Its plumper cousin is the sea biscuit urchin. A sea star washing in is always a thrill, frosted sea glass is the patient collector’s prize, and fossil shark teeth turn up as little black triangles. Then there are the oddities: leathery black mermaid’s purses (skate egg cases) and the curly chains of whelk egg cases that look like dried rattlesnakes.

Working the wrack line

The single best habit a beachcomber can build is to read the wrack line — the curving ribbon of seagrass, sticks and shell hash the high tide drops as it falls back. That’s where the small, light, easy-to-miss finds collect: tiny sand dollars, sea glass smoothed by years of tumbling, the odd tooth. Get there at low tide, right after a cold front or storm has pushed fresh material ashore, and walk slowly with the sun at your back so the glass winks at you. On our trips, the boat-only islands give you wrack lines almost nobody has walked.

Empty and dead only

Here’s the part that matters most. A sand dollar or sea star with any color — brown, purple, gray, or tiny moving spines — is alive, and in Collier and Lee Counties it’s illegal to take live sand dollars, urchins or starfish. Keep only the ones that are bone-white, dry and clearly long dead. Learn to tell a live sand dollar from a dead one, and when in doubt, leave it. The full rules are in our Florida shelling-law guide. Take photos of the living ones — they’re the best souvenirs anyway.

From the Helm: Beach Finds: working the wrack line from Keewaydin to the calmer lee cuts on a falling tide

Before we ever drop the ladder, our captains are already deciding which stretch of shoreline gets the stop. A falling tide on the Gulf side of Keewaydin piles a different wrack line than the calmer lee cuts behind the islands, and the two beaches run differently on the same afternoon. We watch the wind first — a stiff westerly stacks weed and debris high on the open beach, while a light easterly leaves the bay-side flats clean and easy to sort through. That decision, made before anyone steps off the boat, is most of the work.

We like to walk the newest wrack line first, the darker ribbon of seaweed and shell hash marking where the last high tide quit pushing. Older lines, bleached pale and picked over, sit higher and drier up the beach and rarely reward the effort. A fresh line still smells faintly of the Gulf, and the material inside it is loose, not packed — you can run a hand through it and feel individual pieces separate rather than a solid mat. That’s the tell we teach guests in the first minute at the rail.

The best finds turn up fresh, not sun-bleached. A test or a case that’s just washed in still holds some color, a bit of give, sometimes sand still damp in its folds; something that’s tumbled through a few tide cycles goes chalky white and brittle at the edges. We hand guests both kinds when the wrack offers them, so the difference is obvious in the palm rather than explained in words. Most mornings we’re moving guests along the line slowly, letting them set their own pace instead of racing to the next stop.

When the first stretch is picked clean, or the wind swings onshore and churns the water milky, we shift plans rather than force it — running instead to a protected cut where the wrack settles calmer even on a rough day. Guests planning a stop with us can lean on the shelling tours page for the tide logic behind both beach finds and shells, and the full Seashell Guide covers what else typically turns up along the same stretches.

We always remind folks before they start filling a bag: everything we’re collecting today is empty and dead — no live sand dollars, no live starfish, nothing still occupied. Collier and Lee County protect the living animals, and honestly the empty, bleached versions look better on a shelf anyway, without the smell or the guilt. Our captains would rather guests leave with a few honestly empty finds than a bucket of live ones that don’t belong off the beach in the first place.
