由于其大量繁殖对海洋环境的影响，目前舟水动物正在引起全世界的高度关注。 2015年5月27日，我们在南海北部湾实地考察时，发现了中国海域从未有过记录的根口水母标本。在实验室检查了几个标本的形态特征和DNA序列。这些标本具有以下形态特征：半球形伞状，有网状凹槽；八个大的半圆形软瓣瓣与八个八分圆中每个窄瓣交替；侧面扁平的嘴臂有许多扁平的膜质分支，上面有许多球棒和中间丝；非吻合的宽桡管和吻合的窄桡管。这些根口水母的形态特征与Versuriga anadomene的描述一致。此外，线粒体16S rDNA和核18S rDNA基因片段的系统发育分析证实，这些样本与V属于同一簇。 anadyomene 采集于帕劳。因此，该根口水母被鉴定为V。阿纳迪奥梅内。这是 Versuriga 属和 V 种的首次记录。中国海域的Anadyomene。该物种的到来可能归因于来自东南亚沿海水域的物理运输。
Scyphozoans are currently causing great concern worldwide due to the effects of their blooms on the marine environment. During a field survey in Beibu Gulf, South China Sea, on 27 May 2015, we found specimens of a rhizostome jellyfish that had not previously been recorded in Chinese seas. The morphological characters and DNA sequences of several specimens were examined in the laboratory. These specimens had the following morphological characters: hemispherical umbrella with reticular grooves; eight large semicircular velar lappets alternating with narrow lappets in each of the 8 octants; laterally flattened mouth-arms with numerous flat, membranous branches bearing many clubs and intermediate filaments; non-anastomosed broad perradial canals and anastomosed narrow interradial canals. The morphological characters of these rhizostome jellyfish were consistent with descriptions ofVersuriga anadyomene. Furthermore, phylogenetic analysis of mitochondrial 16S rDNA and nuclear 18S rDNA gene fragments confirmed that these specimens were in the same cluster asV. anadyomenecollected in Palau. Therefore, this rhizostome jellyfish was identified asV. anadyomene. This is the first record of the genus Versuriga and the speciesV. anadyomenein Chinese seas. The arrival of this species may be attributed to physical transport from the coastal waters of South East Asia.
