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.

Sand dollars can represent many things spiritually including choosing your own path, strength, flexibility, and freedom. Choosing your own path- sand dollars represent freedom and the ability to walk away from environments or people that are no longer working for you.

When threatened by pink sea stars, a sand dollar buries itself under the sand. Observers have seen a pink sea star leave a wide path of buried sand dollars as it moves across a sand dollar bed.

How Much Is a Sand Dollar Worth? Because sand dollars are so prolific, they are very common. The cost of a live sand dollar for an aquarium might run between five and fifteen dollars. You can pick up a sand dollar skeleton at many local beach souvenir shops from anywhere from a dollar to five dollars.
