In this study we present the first complete mitogenome for the speartooth shark Glyphis glyphis, a rare euryhaline elasmobranch from northern Australia and Papua New Guinea. The mitogenome is 16,702 bp in length and the overall base composition is 31.5% A; 26.0% C; 13.0% G and 29.5% T. It includes 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, 13 protein-coding genes and a putative 1066 bp long control region. The COI gene is initiated by GTG codon whereas the remaining protein-coding genes started with the ATG codon. This study will help elucidate the taxonomy of this poorly known group of sharks.
