Complete mitochondrial genome of the jellyfish, Nemopilema nomurai (Cnidaria: Scyphozoa) and the phylogenetic relationship in the related species.

The complete mitochondrial genome of giant jellyfish Nemopilema nomurai collected from East China Sea was determined by next-generation sequencing. The mitogenome is a circular molecule 17,024 bp in length, including 13 protein-coding genes (including Cox 1, Cox2, Atp 8, Atp 6, ND5, ND 6, ND3, ND41, ND1,ND4, Cytb), 6 tRNAs (tRNA-Trp, tRNA-Met, tRNA-Val, tRNA-Arg, tRNA-Glu, tRNA-Asn), 2 rRNA genes (small subunit RNA and large subunit RNA), and 1 putative control region. The phylogenetic tree in the related species showed that giant jellyfish is close to Hydraoligaclis.
