In this study, we obtained the complete mitochondrial genome sequence ofSphyraena jelloand analyzed its phylogenetic position. The complete mitogenome ofS. jellois 16 699 bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region. Among the 37 genes, 28 were encoded on heavy strand, while 9 were encoded on light strand. The overall base composition was 28.97% for A, 16.14% for G, 29.64% for C, and 25.25% for T, with a higher A + T content (54.22%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested thatS. jellois a sister species toSphyraena barracudain the family Sphyraenidae. This result should be useful for understanding the genetic structure, molecular evolution, and phylogeny ofS. jelloand related species. [ABSTRACT FROM AUTHOR]
