Risso’s dolphin ( Grampus griseus Cuvier, 1812) is the only species of genus Grampus and a cosmopolitan marine inhabitant. Here, we report a polymorphic complete mitochondrial genome of G. griseus . The size of the total mitochondrial genome was 16,386 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. 37 single nucleotide polymorphic sites (SNPs) were identified compared to the references. Based on the available total mitochondrial dolphin genomes’ phylogenetics, G. griseus has formed a clade with 0.1415 distance, sister to the following species of the subfamily Globicephalinae and the taxonomy of Orcinus orca still needs further investigations.
