The record attempt will happen on National Seashell Day!

By Marisa Spyker

Any diehard shell hunter knows it sometimes takes a little digging to find those true diamonds in the sand.

But on June 21 (National Seashell Day!), the greatest find won’t require a shovel and a bucket—instead, it may require an airplane.

Right on the sand in Fort Myers, Florida—a magnet for seashells from the Caribbean and beyond—1,500 people will make history by forming the largest human image of a seashell. (The current Guinness World Record—yes, there is one—is held by Shell Oil Co. and consisted of a mere 855 people in 2017.)

The record attempt, organized by the Lee County Visitor & Convention Bureau, is the signature event of National Seashell Day, a holiday first formed by the beaches of Fort Myers and Sanibel in 2016. On the morning of June 21, participants will gather on the sand in front of Fort Myers’ Outrigger Beach Resort, where they’ll receive matching T-shirts and their spot in the seashell. While all 1,500 slots are full, you can still stop by to watch the historic attempt take place (visitors are also encouraged to bring canned food for donation to area food banks).

And even if you can’t make it to Fort Myers for the event, there are still plenty of ways to shell-ebrate National Seashell Day, like learning about America’s most commonly found sea treasures, displaying your favorite finds around your home, or planning a beachcombing trip to Florida’s idyllic and shell-rich southwest coastline soon. (We’ll be doing all three!)
