    Beschrijving invasiviteit (Engels) The invasiveness of this species is shown by the spread in Poole Harbour, were it spread from pontoons in a marina to the neighboring rocky shores within 5 years and became locally ‘superabundant’ (Bamber 2012). In the Netherlands just two very small samples yielded a total of 17 individuals indicating a high density. Among these and later found specimens were males carrying egg bundles in the ovigers and others with oocytes in advanced development. Thus, although there is no dispersive phase in the species' life cycle, which usually means dispersal will be very slow, further spread in the Netherlands is to be expected. (See also NB)
    Beschrijving (potentiële) ecologische impact (Engels) According to R.N. Bamber (JNCC 2006) there are no effects on the environment known. This is also the case in The Netherlands. Theoretically spoken however, there may be some competition for food and space with other indigenous (and introduced) sea-spiders and other fauna-elements.
    Beschrijving (potentiële) economische impact (Engels) Effects on commercial interests are unknown (JNCC 2006). This is also the case in The Netherlands.
    Beschrijving verspreiding binnen Nederland (Engels) A. hilgendorfi originates from the Mid- and North Pacific, where it lives in the tropical and temperate North Pacific littoral zone of south-east Asia, including a.o. Japan and the Westcoast of America: Bamber, 2012). In 1979–1981 it was found near Venice in the Mediterranean, probably introduced via intercontinental shipping (Krapp & Sconfetti 1983). In 1978 and in 1988 it was found near Southampton in south England (Bamber 1985) and later dispered to other localities (Bamber 2012). The first record from the Atlantic coast of continental Europe is from the Netherlands, where it most certainly did not live before (Wolff 1976, 2005). A total of 17 specimens were found in bottom material on 31 August 2013, soon followed by other records from the Oosterschelde-area (Perk & Faasse 2014). As yet the occurrence in the Netherlands is still local (province of Zeeland), but further expansion is to be expected. Faasse (2013) discusses the probability of the species being transported from England to The Netherlands with (recreational) vessels, but also mentions the fact that the species was found on a former mussel plot in The Netherlands, which suggests that imported shellfish could have been a vector for primary introduction.
