The complete mitochondrial DNA genome of the Queensland seahorse Hippocampus queenslandicus Horne, 2001 (Gasterosteiformes: Syngnathidae)

The complete mitochondrial genome of the Queensland seahorse Hippocampus queenslandicus Horne, 2001 (Gasterosteiformes: Syngnathidae) has been amplified and sequenced in this study. The mitogenome was 16,527 bp long with protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region. The overall base composition of the genomes was 32.2% for A, 30.1% for T, 14.9% for G, and 22.8% for C with an A + T-rich characteristic (62.3%). According to the phylogenetic analysis, H. queenslandicus showed a closer genetic relationship with H. spinosissimus.
