Mitochondrial genome of the spotless smooth-hound Mustelus griseus (Carcharhiniformes: Triakidae)
Mitochondrial DNA Part A, 2014The complete mitochondrial genome of Mustelus griseus was first determined in this study. It is 16,754 bp in length, consisting of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region with the typical gene order in vertebrates. Overall nucleotide base composition of the mitogenome is 30.7% A, 24.9% C, 14.0% G and 30.3% T.

Complete mitochondrial genome of the blue sharkPrionace glauca(Elasmobranchii: Carcharhiniformes)
Mitochondrial DNA, 2013In this study, we first presented the complete mitochondrial genome of the blue shark Prionace Glauca, a pelagic and oceanic species. It is 16,705 bp in length and contains 2 rRNA genes, 22 tRNA genes, 13 protein-coding genes and 1 putative control region. The overall base composition is 31.6% A, 24.4% C, 13.1% G and 30.9% T.

AbstractThe triple‐layered enameloid organization of neoselachian teeth has proven to be a reliable systematic character of the group. This study uses scanning electron microscopy to investigate the orientation of the parallel enameloid bundles in the area of the serrated cutting edges in certain fossil elasmobranchs.

This paper examines the alpha level taxonomy of the genus Haploblepharus Garman, 1913 (Chondrichthyes; Scyliorhinidae). Three species are endemic to South Africa, with one species occurring in Namibia and South Africa. Haploblepharus pictus exhibits considerable colour variation which has led to some confusion between that species and H.

A new species of catshark (Carcharhiniformes, Scyliorhinidae), Scyliorhinus ugoi sp. nov., is described from off Northeastern and Southeastern Brazil. The new species is closest to the Scyliorhinus haeckelii/besnardi group and S. hesperius but differs in background coloration, head width, sexual maturity, and in cranial and body proportions.
