The pteriomorphs are a large clade of mostly epifaunal bivalves that consistently occupy a fairly basal position within the Bivalvia
In the latter site, the polychaetes of the family Capitellidae and the class Bivalvia
were the most abundant, with 114 and 44 individuals respectively.
Benthic communities are usually dominated by different species of polychaete, oligochaete worms, gastropods, bivalvia
and various minor insect larvae.
Dentro de los moluscos, Bivalvia
es la clase especializada para perforar y vivir bajo la superficie de un sustrato firme como rocas, corales y estructuras arrecifales, entre otros.

Besides Oligochaeta, Chironomidae maggots and Bivalvia
These layers, composed primarily of protein, have been retained throughout the evolutionary history of the Corbulidae despite the high metabolic cost of the protein fraction of the shell (Palmer 1983, 1992) and the repeated evolutionary tendency within the Gastropoda and Bivalvia
toward loss of organic-rich microstructures from the shell (Taylor 1973; Carter 1980).
