Abstract

We determined the complete mitochondrial genome of the Atlantic Gnomefish, Scombrops oculatus (Scombropidae). The total length of mitochondrial DNA (mtDNA) was 16,515 bp and included 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one control region. The gene arrangement of S. oculatus was identical to those of three Japanese scombropid species and those of other teleosts. The phylogenetic analysis using the whole mtDNA, excluding the control region, indicates the Atlantic species is distinct from the Japanese clade, whereas that using cytochrome c oxidase subunit I gene showed the Atlantic species is most closely related to the African species.
