This study presented the complete mitochondrial genome of the Torpedo scad Megalaspis cordyla, the only member of its genus, as well as its phylogenetic position in Carangidae. The genome is 16,566 bp containing the usual 2 rRNA genes, 13 protein-coding genes, 22 tRNA genes, and 1 control region. Gene organization is similar to that observed in most other vertebrates. Gene overlapping and separating were also observed in M. cordyla mitogenome. The overall base compositions of mitogenome was 28.83% A, 25.81% T, 15.93% G, and 29.43% C. Phylogenetic analyses using the concatenated sequence of the protein-coding genes of the reported Carangidae mitogenome showed similar results in the neighbour-joining and Bayesian inference trees. Three clades were formed as Subfamilies Caranginae, Seriolinae and Trachinotinae in Carangidae. M. cordyla was most closely related to the species in genus Caranx.
