The complete mitochondrial genome sequence and phylogenetic analysis for Inimicus japonicus (Scorpaeniformes: Synanceiidae)

The complete mitochondrial genome (mitogenome) of the Inimicus japonicus was analyzed by next-generation sequencing in this study. The mitogenome is 16,978 base pairs (bp) long and codes for 22 transfer RNA (tRNA) genes, 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNA), and 1 non-coding control region. The overall nucleotide composition of the mitogenome is: 29.61% for A, 29.16% for T, 25.26% for C, and 15.97% for G. Twenty-two tRNAs range from 67 to 74 bp in length, and 2 rRNA (12S and 16S) were 953 and 1,687 bp long, respectively. Phylogenetic analysis by neighbor-joining (NJ) method indicated that I. japonicus showed considerable genetic similarity (82%), and had a closer relationship in the phylogenetic tree to Synanceia verrucosa.
