Complete mitochondrial genome of the jellyfish, Chrysaora pacifica (Goette, 1886) (Cnidaria, Scyphozoa) and the phylogenetic relationship in the related species

Abstract

The complete mitochondrial genome sequences of giant jellyfish Chrysaora pacifica, a scyphozoan species inhabiting the Bohai Sea water in China, is firstly described and analyzed in this research. The mitogenome is a circular molecule 16,964 bp in length, including 13 protein-coding genes (Cox 1, Cox2, Atp 8, Atp 6, Cox 3, ND2, ND5, ND 6, ND3, ND4L,ND1,ND4, Cob), 2 tRNAs (trnW, trnM), 2 rRNA genes (small subunit RNA and large subunit RNA). The neighbor-joining (NJ) phylogenetic tree in the related species showed that C. pacifica is close to Chrysaora quinquecirrha.
