For example, some experts say the removal of shells can impact shoreline erosion patterns. This could have dire effects on coastal populations, especially in combination with global warming and rising sea levels. Not only that, but every shell performs some ecological role.
Although January, February and March are some of the best months to go shelling on Sanibel and Captiva, Stefanie Wolf, a marine biologist at the Bailey-Matthews National Shell Museum, said that because of the high winds the islands have been experiencing this spring, now is an opportune time to go shelling.
In fact, Sanibel Island is known as the “Seashell Capital of the World” because of its unique east-west orientation that brings countless seashells in pristine condition to its white-sand beaches.
It has been estimated that there are only 50,000 conches still in existence across the globe. The vast majority of conch shells typically have a high and curled spire, which is the twisted point at the end of the shell. They also have a very noticeable siphonal canal.
The general agreement is that there are three best times to go shelling: early in the morning, at low tide, and at night. If you go early in the morning, you will have a lot more shells on the beach and the visibility of that time of day will make it generally easier to see them.
The Real Reason Sanibel Has an Abundance of Great ShellsIt's because it's one of the very few islands that run perpendicular to the state of Florida, whereas most islands run the same way as Florida, which causes the ocean currents to have the beaches primarily flushing water downward.
A Unique Geography. The reason why Sanibel Island and Captiva Island beaches in particular are filled with shells is because both are barrier islands that are part of a large plateau in the Gulf of Mexico. A ground level swell pushes shells to this natural “shelf” and on to its beaches largely in tact.
