Abstract

The genetype of Chlamydoselachus anguineus 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 C. anguineus 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 C. anguineus genomes (>99.9% genetic identity) is consistent with a widespread population in the west Pacific Ocean.
