What is dentalium shells?

Dentalium shells are long, tubular mollusk shells that belong to the scaphopod family. They are commonly known as "tusk shells" due to their elongated, tusk-like shape. These shells are typically smooth, cylindrical, and come in a range of sizes, from a few millimeters to several centimeters in length.

Dentalium shells are found in oceans worldwide, primarily in sandy or muddy seabeds, where they burrow into the substrate for protection. They are filter feeders, using a foot-like appendage to capture plankton and other small particles from the water.

In some indigenous cultures, dentalium shells have historically been used as currency, jewelry, and adornments. They hold cultural significance in many Native American tribes, where they are often used in traditional regalia and ceremonies.

Overall, dentalium shells are valued for their unique shape, durability, and versatility in various cultural and artistic practices.
