Nota sobre la biologia de los depositos fangosos circalitorales frente a Punta del Este, Uruguay

Abstract

A circalitoral muddy bottom community is studied off Punta del Este, Uruguay. From this study a relevant fact is observed: the coexistence between deposit-feeders and suspension-feeders. It has long been thought that they are excludent trophic groups. The coexistence may be explained by the deposit stability favourished by a dense population of the tube-building polychaete Onuphis setosa.
