Cover Story (view full-size image): Chondrichthyes (sharks, sawfish, skates, rays, and chimaeras) represent a species-rich lineage of cartilaginous fishes and occupy a key position in the phylogeny of vertebrates. We sequenced and annotated the complete mitogenomes of four species of sharks and five species of rays. Subsequently, we analyzed mitogenomes from public databases and reconstructed the phylogenetic relations of 172 chondrichthyan species by maximum likelihood and Bayesian inference methods based on the concatenated sequences of the 13 protein-coding mitochondrial genes. The present study expands our knowledge on the systematics and genetic differentiation of Chondrichthyes and contributes to our understanding of their evolutionary history. View this paper
