Genetype and phylogenomic position of the frilled shark inferred from the mitochondrial genome.

The genetype of from Australian waters is described using the whole mitochondrial genome obtained from Illumina NGS technology. Total length of the mitogenome is 17 313 bp, consisting of 2 rRNAs, 13 protein-coding genes, 22 tRNA genes and 2 non-coding regions thus updating the previously available mitogenome for this species. The phylogenomic reconstruction comprising all available species of Superorder Squalomorphi supports the inclusion of . in a divergent clade inside Order Hexanchiformes. Phyletic relationships inferred from the whole mitochondrial genomes are in agreement with traditional taxonomy. The low divergence between genomes (>99.9% genetic identity) is consistent with a widespread population in the west Pacific Ocean.
