The '''dog cockle''', or '''European bittersweet''' (''Glycymeris glycymeris'',) is a saltwater[[species]] of [[marine (ocean)|marine]] clam, a [[coast]]al [[bivalve]] [[mollusc]] of [[Europe]]an waters. Despite the name, it is not closely related to the [[Common cockle]].
 
Despite its [[common name]], it is not closely related to the [[common cockle]].
The dog cockle is a burrowing animal, living in shelly [[gravel]] at depths up to 100 [[metre|m]].
 
While the English [[common name]] "dog cockle" implies an inferior food that might only be suitable for animals, this shellfish is edible and enjoyed in many European countries,<ref>Wendy Sweetser, ''The Connoisseur's Guide to Fish & Seafood'' (Sterling, 2009), p. 137.</ref> although the flesh has a reputation for becoming tough if overcooked. Its name in French (''amande de mer'') and Spanish (''almendra de mar'') means "sea almond", due to its apparently sweet and almond-like flavour.<ref>"Amande de mer: smooth-shelled shellfish, like a small clam, with a sweet, almost almond flavor."

The shell, which reaches 6.5 [[centimetre|cm]] in length, is thick and almost circular. The anterior hinge line curves more steeply downwards than the posterior. The shell varies in colour, being brown, yellow or a light purplish-red in colour. It can be uniformly coloured, or it can show irregular, concentric zigzags on a cream background. The [[periostracum]] is dark brown and forms a broad band around the shell margin; it is [[velvet]]y in texture. The inside of the shell is normally brown within the [[pallial line]]. The inner surface of the shell has 6 to 12 teeth on either side of the beak.
