The term "sand dollar" refers to the round flat shape of the rigid endoskeleton which apparently reminded American sailors and sea-farers of a large coin when they spoted them washed up on beaches, bleached a dazzling white by the sun. This comparison to coinage and money led to the eventual use of the term "fortune" to describe a large group of these marine animals, which can congregate by the hundreds on sandbars just below the surface of the sea floor.
