Whāingaroa (Raglan) Harbour - estuary monitoring results

Sediment-dwelling organisms

Bivalves (shellfish – cockles) and polychaetes (marine worms) are the major components of the sediment-dwelling organism communities at all five Whāingaroa (Raglan) Harbour monitoring sites. Crustaceans (amphipods – shrimp like, crabs) were relatively abundant at all monitoring sites. Gastropods (snails) are more rare and not found at all sites in Whāingaroa (Raglan) Harbour.
