An introduced species, this colonial ascidian can be found in estuarine environments, in a variety of colours, from translucent grey to greenish or reddish. Each cushion has one or more large shared cloacal apertures, almost invisible due to a lack of pigmentation on the rim. In contrast, the branchial apertures have a thick white rim that is circular, with slightly pinched ends. This species is not easily mistaken for any others known to be present in SA.
