The phylogenomic position of the Critically Endangered Largetooth Sawfish (Rhinopristiformes, Pristidae), inferred from the complete mitochondrial genome.

The complete mitogenome of the Critically Endangered Largetooth Sawfish (Rhinopristiformes, Pristidae) is presented in this study. The genome is 16,912 bp in length with a nucleotide base composition of 32.0% A, 26.5% C, 13.2% G, and 28.3% T, containing 37 genes typical of vertebrates. Two start (GTG and ATG) and two stop (TAG and TAA/T) codons are found in the protein-coding genes. The 22 tRNA genes range from 66 bp (tRNA-Ser2) to 75 bp (tRNA-Leu1). The tRNA-Pro gene is duplicated with an unknown sequence between the two copies. Bayesian phylogenetic reconstruction showed that clusters with the clade with strong posterior probability (100%).
