Abstract
We sequenced and annotated the complete mitochondrial genome of Ctenochaetus tominiensis (Randall 1955) from Indonesia. The genome was assembled into a circular molecule of 16,429 bp with 44.45% GC content. This genome consisted of 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and 1D-loop. Phylogenetic analysis based on 13 PCGs showed that Ctenochaetus and Acanthurus were recovered in a single clade. The mitochondrial genome of C. tominiensis is helpful for species identification and phylogenetic position of fish.
