ECOLOGY OF BENTHIC POLYCHAETES IN THE HEATHCOTE ESTUARY, NEW ZEALAND

New Zealand Oceanographic Institute, Department of Scientific and Industrial Research, Wellington

Abstract The distributions of 19 species of polychaetes burrowing in the intertidal sand and mudbanks of the Heathcote Estuary, New Zealand, are related to salinity, sediment grade, and length of time of exposure at low tide. Only Nicon aestuariensis Knox and Scotecolepides benhami Ehlers appear to be truly estuarine species reaching their greatest population densities in low salinities. Incidental observations of feeding and reproduction are reported.
