…COLLECTING SHELLS FROM THE BEACH COULD IMPACT THE ECOSYSTEM?

In addition to serving as a home for other animals, an empty shell also releases a substance called calcium carbonate, which enriches the marine habitat. In Brazil, anyone who removes any material from aquatic environments without authorization could receive a sentence of one to three years in prison.

…AFTER AN ANIMAL DIES, ITS SHELL CAN BE REUSED BY ANOTHER CREATURE?

Hermit crabs, for example, carry a shell to protect themselves from other animals and to keep their bodies hydrated when they are on the surface.

…SHELLS ARE PRODUCED BY LIVING BEINGS?

Aquatic animals, such as mollusks, build shell structures (also called exoskeletons) to protect themselves from predators.

…YOU CAN HEAR A SOUND LIKE THAT OF THE OCEAN WHEN YOU HOLD CERTAIN TYPES OF SHELLS CLOSE TO YOUR EAR?

This happens with shells that have a spiral-shaped interior, which reverberates and echoes ambient noises, giving the impression that you are listening to the ocean.
