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 .

Description

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.

Distribution

Donax fossor lives from the coast of New York State south through New Jersey, Maryland, Virginia, and North Carolina, to East Florida. [3]

Biology

In New Jersey, on exposed beaches, this small bivalve often has the hydroid Lovenella gracilis growing on the posterior tip of the shell. There is some evidence that this protects the clam against predation attempts by the moonsnail Neverita duplicata . [4]

<i>Donax</i> (bivalve) Genus of molluscs

Donax is a genus of small, edible saltwater clams, marine bivalve molluscs. The genus is sometimes known as bean clams or wedge shells; however, Donax species have numerous different common names in different parts of the world. In the southeastern US they are known as "coquina", a word that is also used for the hard limestone concretions of their shells and those of other marine organisms.

Scotch bonnet (sea snail) Species of mollusc

The Scotch bonnet is a medium-sized to large species of sea snail, a marine gastropod mollusk in the subfamily Cassinae, the helmet shells and bonnet shells. The common name "Scotch bonnet" alludes to the general outline and color pattern of the shell, which vaguely resemble a tam o' shanter, a traditional Scottish bonnet or cap. The shell is egg-shaped and fairly large, 2 to 4 inches in maximum dimension, with a regular pattern of yellow, orange or brown squarish spots. The surface sculpture of the shell is highly variable: the surface can be smooth and polished, have grooves, be granulated, or even be nodulose on the shoulder of the whorls.
