    Beschrijving invasiviteit (Engels) This species is considered a serious pest outside its native range (Northwest Pacific). It is spreading rather rapidly and has the ability to overgrow almost everything, covering large areas in a relatively short period. Within a year after the first record in the Netherlands, the species has developed into a dominant species in the Eastern Scheldt and locally in Lake Grevelingen and the Western Scheldt. It already has spread to the Dutch part of the Wadden Sea (Gittenberger 2007, Gittenberger et al. 2010).
    Beschrijving (potentiële) ecologische impact (Engels) Indigenous species are overgrown and/or diminish through competition. In this respect this colourful species will have an obvious impact on the ecosystem in the Dutch province of Zeeland and the Wadden Sea.
    Beschrijving (potentiële) economische impact (Engels) In the Netherlands until now there is no evidence of economical impact.
    Beschrijving verspreiding binnen Nederland (Engels) This species was found in 1999 in the Oosterschelde in 'Het Zijpe' (Gittenberger & Schrieken 2000b) from where it spread through mainly the eastern part. Later it was also recorded from Lake Grevelingen (Gittenberger 2007) and the Wadden Sea (Gittenberger et al. 2010). The species first was recorded under a different name: B. leachi. It is highly likely that at least part of the West-European records of B. leachi will prove to be in fact B. violaceus. The 'Slingerzakpijp' B. violaceus can be confused with another Botrylloides-species: Botrylloides cf diegensis, which is already recorded from the Netherlands (Faasse 2006).
