National Seashell Day – June 21, 2024

National Seashell Day is celebrated every year on the first day of summer — on June 21. This day encourages you to head to your nearby beach and admire the beautiful shells left behind by creatures, typically snails and mollusks. There are so many different types of shells that you can find on beaches, all you have to do is look. However, make sure you only pick up empty shells and not ones with creatures still living inside them. If you do find such shells, it’s best to release them gently back into the ocean. Get ready to head to sandy beaches where seashells await you!

History of National Seashell Day

National Seashell Day was founded by Lee County Visitor & Convention Bureau on the first day of summer in 2016. This day was created as a marketing gimmick to attract tourists to celebrate the seashells found on the beaches of Fort Myers and Sanibel in Southwest Florida. National Seashell Day was first celebrated on Captiva Island with the morning TV news show called “Good Morning, America.”

Did you know Sanibel Island has earned the title of the Seashell Capital of the World, owing to its abundance of seashells? Every year, people flock to Captiva and Sanibel Islands to search for over 400 species of shells. The calm waves and location make these islands the top pick for people to look for beautiful seashells.

However, while shelling is allowed, it is illegal to collect live shells, which is any shell that still has an inhabitant. The shell serves as their home and it is cruel to disrupt their environment. This day is also celebrated to alleviate the issue of the illegal shell trade. In fact, shellers are also encouraged to keep their empty shell collection to a minimum.

National Seashell Day is an ideal opportunity to simply be grateful for the existence of the beautiful shells that are home to certain sea creatures.
