A tunicate that forms large colonies.
To help protect our environment:
Hard surfaces such as marinas and rocky sub-tidal and inter-tidal habitats.

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.
