Other bivalves of commercial importance known to suffer severe growth retardation include the mussel (Mytilus edulis) and the palourde (Tapes decussatus), while the Manila clam (Tapes philippinarum) has proved to be quite resilient. Species of molluscs other than bivalves affected by TBT poisoning include the dogwhelk (Nucella lapillus) and offshore populations of the common whelk (Buccinum undatum) where they occur near to major shipping lanes. Rather fortuitously, the introduced American tingle (Urosalpinx cinerea), a major pest of flat oysters in Essex and Kent in the 1940s to 1960s, has also suffered severely from TBT poisoning.

Shell and mantle The most obvious feature of the bivalve is the shell, consisting of two calcified valves joined together by an uncalcified elastic ligament. The outer fold of the edge of the mantle secretes the shell. g. scallops, eyes. During growth, the shape of the shell depends on the amount of marginal increase around the mantle rim. With unattached bivalves such as cockles and clams, there is symmetry around both ends, producing a rounded cockle shape or an oval venerupid shape.
