Bittersweet Clams [Glycymeris]

Description

Glycymeris is a genus within the family Glycymerididae, known commonly as bittersweet clams. These bivalves are characterized by their robust, equivalve shells that are often rounded or ovate in shape. The exterior of the shell features concentric growth rings which may be pronounced or subtle, depending on the species. The interior is notable for its glossy surface, often displaying a pearlescent quality. Glycymeris species inhabit a range of marine environments from shallow to deep waters, typically burying themselves in sandy or muddy substrates where they filter-feed on plankton and detritus. The genus is widespread, found in oceans around the world, and includes species of both commercial and ecological importance.
