Description

Thin Tellin (Tellina tenuis)
Very thin brittle, flattened, brightly coloured shells (pink, orange or white) often still hinged together. Found on fine sand. Up to ¾ inch. Common

or Bivalve ..

Bivalves can be grouped into a number of functional groups i.e. oysters, boring bivalves, mussels and false mussels. To find more information on the specific groups please follow the links below
The Bivalvia is a class of Mollusca, like Gastropoda (snails and slugs), Cephalopoda (squid, cuttlefish and octopus), Polyplacophora (chitons) and Scaphopoda (tusk shells). The bivalve shell is composed of two valves ("bi-valves"). The valves are joined by a hinge composed of tiny "teeth" and usually also an elastic ligament. The number, size and shape of the teeth as well as the position of the ligament are important characters for the identification of bivalves. In addition bivalves have one or two strong adductor muscles, which are responsible for the closing of the valves. They attach to the inside of both valves and leave more or less distinct "scars" that are also used for identification. The shell is composed of calcium carbonate embedded in an organic matrix. The shell is secreted from the mantle, a thin tissue fold covering the body of the bivalve. Externally the shell usually has a thin organic layer, the periostracum, which is often pigmented. The inner surface is nacreous ("mother-of-pearl"), and scars from attachment of muscles and mantle edge are visible
