Top 10 Rarest Seashells

What are seashells?

Seashells are the shells of mollusks, which are a type of marine invertebrate. They come in an extraordinary variety of shapes, sizes, and colors – from spiral-shaped conch shells to fan-like scallop shells. As mollusks live their lives underwater, many seashells can only be found in shallow coastal areas or even further out at sea. This means that beachcombers have to be alert and determined if they want to find some of the rarest specimens!
