A tunicate that forms colonies of transparent tubes about 5cm long, with white, yellow or pink bands that make it appear to glow like a light bulb.
To help protect our environment:
Can form large colonies on hard surfaces such as marinas and rocky sub-tidal and inter-tidal habitats. The lightbulb tunicate is most commonly spread as fouling on boat hulls.
This species is relatively newly documented as an invasive species, so its potential impacts are still uncertain. However, given its ability to form large colonies, it is likely to be able to outcompete native species and may impact upon the mauri of the moana.
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.
