“…Recently, a growing number of newly-recorded scyphozoan species have been reported in different areas of the world's oceans (e.g., Çevik et al, 2006;Gershwin and Zeidler, 2008;Ocaña-Luna et al, 2010;Yahia et al, 2013;Deidun et al, 2017;. Some species were confirmed as invasive or alien species, including Phyllorhiza punctata, Rhopilema nomadica, Marivagia stellata, Cotylorhiza erythraea, and Cassiopea andromeda in the Mediterranean (Çevik et al, 2006;Galil et al, 2009Galil et al, , 2010Yahia et al, 2013;Deidun et al, 2017), and P. punctata in the Gulf of Mexico (Ocaña-Luna et al, 2010). Dispersal in the South China Sea is not restricted, and thus we infer that the rhizostome jellyfish V. anadyomene in the Beibu Gulf may have been transported from the waters of Southeast Asia, i.e., Malaysia, the Philippines, or Indonesia.…”
