The complete mitochondrial genome of the hydrozoan jellyfish Turritopsis lata Lendenfeld, 1885 (Cnidaria; Hydrozoa; Anthoathecata) with molecular phylogenetic analysis.

In this study, we sequenced and analyzed the complete mitochondrial genome (mtgenome) of the hydrozoan jellyfish Turritopsis lata. The mtgenome was a complete linear form (15,047 bp in length, 30.9% A, 42.1% T, 12.5% C, and 14.5% G), including 13 protein coding genes (PCGs) (cox1, cox2, cox3, atp6, atp8, nad1, nad2, nad3, nad4, nad4L, nad5, nad6, and cytb), 2 tRNAs (tRNAMet and tRNATrp), and 2 rRNAs (12S and 16S rRNA). The genome structure of the T. lata was completely identical to those of other species within the subclass Hydroidolina. In addition, our molecular phylogenetic analysis using 13 PCGs within hydrozoans showed that T. lata was the closest to Turritopsis dohrnii.
