Description
The Coarse Dosinia is a species of marine bivalve mollusk known for its robust, nearly circular shell. It is characterized by prominent, regular, concentric ridges on its exterior surface, giving it a 'coarse' texture. The shell is typically thick and heavy, with a smooth, glossy white interior. These clams are infaunal, burrowing in sandy or muddy substrates.
