    How can polychaetes be used to monitor the quality of the environment? They accumulate toxic compounds and are therefore often found in polluted waters where they out-compete less tolerant species Why is the presence of Capitella capitata in a marine environment significant? The Río de la Plata is an extensive and shallow coastal plain estuary on the western South Atlantic coast (35–36°S).
