Jellyfishes of the order Rhizostomeae include ecologically and economically important species predisposed to forming massive aggregations. This study reports the first complete mitochondrial genome of two rhizostomes: (Forskål, 1775) and Stiasny, 1920. The linear mitochondrial genomes are 16,667bp and 16,707bp in length and 65.5% and 68.4% AT respectively; each comprises 15 protein-coding genes (PCGs; dpo, orf314, cox1-3, nd1-6, nd4L, atp6, atp8 and cytB), two ribosomal RNAs (16S and 12S rRNA), and two tRNAs (trnM and trnW). The phylogenetic analysis reveals strong support for monophyly of the suborder Kolpophorae and of the infraorder Actinomyaria as sister to Krykomyaria which includes .
根口水母目水母包括在生态和经济方面具有重要意义且易于形成大规模聚集的物种。本研究报告了两种根口水母的首个完整线粒体基因组：（福尔斯科尔，1775年）和（斯蒂亚斯尼，1920年）。线性线粒体基因组长度分别为16,667bp和16,707bp，AT含量分别为65.5%和68.4%；每个基因组包含15个蛋白质编码基因（PCGs；dpo、orf314、cox1 - 3、nd1 - 6、nd4L、atp6、atp8和cytB）、两个核糖体RNA（16S和12S rRNA）以及两个tRNA（trnM和trnW）。系统发育分析显示，有力支持了钵口亚目的单系性以及与包括在内的克里科水母亚目为姐妹群的放线肌亚目的单系性。
