In eastern Canada, the common sand dollar (Echinarachnius parma) forms dense groups called beds that occur from shallow intertidal waters out to the offshore continental shelves (Figure 17). Contrary to their name, sand dollars are found in a range of sediment types, from coarse gravelly sand to fine silt.

We often find sand dollars on our beaches, and their beautiful skeletons make a great souvenir, but it's illegal to collect them when they are alive.

In addition to their religious symbolism, Sand Dollar represents wealth and abundance. Their delicate, intricately patterned shells are considered lucky finds. Overall, they signify transformation, rebirth, prosperity, spiritual growth, and awakening.

California sheephead, starry flounders and large pink sea stars prey on the sand dollar. When threatened by pink sea stars, a sand dollar buries itself under the sand.
