A large tube-dwelling bristle worm typically found in estuaries and sheltered sites up to depths of around 30 metres. It has a flexible, leathery tube, up to 80 centimetres tall, topped with a single, spiral fan of feeding tentacles, often banded orange, purple or white.
To help protect our environment:
Attaches to a wide variety of hard surfaces including rocks, wood, steel, concrete, shellfish and artificial materials, and is most commonly spread as fouling species on moored vessels.
Can form dense beds that are likely to out-compete other species, clog fishing gear and dredges, and interfere with biological processes. It has the potential to compete with native filter-feeding organisms for food and space which can impact upon the mauri of the moana.
In high densities, Mediterranean fanworm is likely to also impact commercially on important kaimoana species including kuku / kūtai (mussels), tio (oysters), and tipa / tupa (scallops).
Before moving your boat or other craft to new locations, make sure the hull, anchor chain and all other equipment on board is clean and free of marine pests or other fouling. Think about where you’re taking on or releasing ballast, bilge or holding tank water, or water in any other container such as chilly bins, to avoid spreading marine pests.
