Donax fossor is a species of small saltwater clam, a marine bivalve mollusc species in the family Donacidae. This species is native to the eastern coast of the US, as far north as New York State; in the past it was sometimes incorrectly considered to be a northern, less colorful form of Donax variabilis.
This small clam was reported in the literature to attain a maximum length of 18 mm.[2] The shell can be almost white in color, or yellow, orange, greyish, or purplish. The darker shells may be rayed with purple on the inside, but these rays are usually only rather faintly visible on the outside.
