The '''dog cockle''' or '''European bittersweet''', (''Glycymeris glycymeris'',) is a [[species]] of [[marine (ocean)|marine]] clam, a [[coast]]al [[bivalve]] [[mollusc]] of [[Europe]]an waters.
 
Despite its [[common name]], it is not closely related to the [[common cockle]].
 
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. In France it is called an ''amande de mer'' or "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."

==Habitat==
The dog cockle is a burrowing[[burrow]]ing animal, living in shelly [[gravel]] on the [[ocean floor]] at depths up to 100  m (330 ft).
 
==Shell description==
The shell, which reaches 6.5  cm in length, is thick, and almost circular in outline. 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 6six to 12 teeth on either side of the beak.
