Sand dollars breathe through a process known as diffusion, using their tube feet.

Sand dollars are typically found in sandy, shallow waters along the coasts of the Atlantic and Pacific Oceans, where they thrive in specific environmental conditions. The Louisiana coast, characterized by its muddy, brackish waters and significant freshwater inflow from the Mississippi River, does not provide the ideal habitat for sand dollars. Additionally, factors such as strong currents and the presence of marshlands can further limit their distribution in this region. As a result, sand dollars are rarely, if ever, found along the Louisiana coast.
