Next-generation sequencing yields the first complete mitochondrial genome of the ruby dragonet (Syngnathiformes, Callionymidae).

The complete mitogenome sequence of the ruby dragonet was first determined using next-generation sequencing strategy in this study. The circle genome was 16,656 bp in length and consisted of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and 1 control region. The mitochondrial gene arrangement of is similar to those of most other fish species. Results from neighbor-joining phylogenetic analysis showed that clustered with and other species of the family Callionymidae. This study will be valuable for phylogenetic analysis of the genus and the other genera of the order Syngnathiformes.
