Sand dollars inhabit sandy or muddy ocean floors and often coexist with various marine organisms. Common companions include sea cucumbers, small crabs, and various species of sea urchins. Additionally, they may share their environment with mollusks, polychaete worms, and other benthic invertebrates that thrive in similar habitats. These interactions create a vibrant ecosystem on the ocean floor.
