Donax is a genus of small, edible saltwater clams, marine bivalve molluscs with highly variable color patterns. The genus is sometimes called bean clams or wedge shells; however, Donax species bear different common names in different parts of the world. In the southeastern United States, they are called "coquina", a word that is also used for the hard limestone concretions of their shells and those of other marine invertebrates.
