Live Sand Dollar (Echinarachnius parma)
Please Note This Is A, Live Science Specimen

The Sand Dollar (Echinarachnius parma) is a flat, burrowing echinoderm commonly found in shallow sandy areas along the Gulf of Maine’s coast. Its distinctive disk shape and intricate surface patterns make it a fascinating specimen for marine education and live display. When alive, sand dollars are covered with tiny purple spines and tube feet that they use for movement and feeding — a key adaptation to life in shifting sand environments.

Perfect for marine biology classes, aquariums, or touch tank exhibits, these live specimens help students and visitors observe real-time echinoderm behavior, symmetry, and anatomy.

Take a quick tour of a low tide sandy cove with Tidepool Tim as he views thousands of live Sanddollars on a beach in Eastern Maine.

Tidepool Tim says, "It's important to recognize the difference between a dead sand dollar and a live one! You may have seen bright white sand dollars for sale in gift shops, these are definitely bleached, and definitely dead. Dead dollars on the beach will usually be a much lighter color than live ones, probably a tan or light grey color. These have smooth bottoms. In contrast, live dollars have 'fuzzy' bottoms, which are their tube feet."
