Abstract In an effort to provide a framework for the accurate identification of elasmobranchs, driven in large part by the needs of parasitological studies, a comprehensive survey of DNA sequences derived from the mitochondrial NADH2 gene was conducted for elasmobranchs collected from around the world. Analysis was based on sequences derived from 4283 specimens representing an estimated 574 (of ∼1221) species (305 sharks, 269 batoids), each represented by 1 to 176 specimens, in 157 (of 193… 
A molecular approach towards taxonomic identification of elasmobranch species from Maltese fisheries landings.
Taxonomic assessment of sharks, rays and guitarfishes (Chondrichthyes: Elasmobranchii) from south-eastern Arabia, using the NADH dehydrogenase subunit 2 (NADH2) gene
The results provide strong molecular support for the existence of an undescribed Echinorhinus species and for cryptic speciation within Rhynchobatus djiddensis, and reinforce previously reported geographical divisions within certain putative species, which has important implications for fishery management and conservation.
Mitochondrial DNA sequencing of a wet-collection syntype demonstrates the importance of type material as genetic resource for lantern shark taxonomy (Chondrichthyes: Etmopteridae)
This study illustrates the importance of mitochondrial DNA from an aged, wet collection type specimen for taxonomy by shotgun-sequencing additional 9 million reads from this same DNA library and confirming the almost global distribution of E. pusillus.
Patterns of specificity and diversity in species of Paraorygmatobothrium Ruhnke, 1994 (Cestoda: Phyllobothriidae) in Moreton Bay, Queensland, Australia, with the description of four new species
The findings of this study indicate that the description of species of this genus on the basis of morphological data alone is problematic and that the inclusion of multi-locus molecular data is essential for future work on Paraorygmatobothrium.
New insights into the identities of the elasmobranch fauna of Sri Lanka.
The high amount of novelty discovered as a result of a survey of such short duration emphasizes the importance of more intensive survey efforts in this region now that the civil unrest that precluded such work for nearly three decades has come to an end.
Occurrence of Apristurus species in the Galicia Bank Seamount (NE Atlantic)
These are the first records of the Apristurus species from Galician waters, which extends their known area of distribution and provides more information on different biological and ecological aspects of this complex taxonomic group.
A New Genus of Tapeworm (Cestoda: Onchoproteocephalidea) from Sawfish (Elasmobranchii: Pristidae)
Abstract Collections from the dwarf sawfish, Pristis clavata, near Darwin, Australia, in 1997 led to the discovery of the new onchoproteocephalidean genus Matticestus n. gen.—a taxon that has been


A test of the utility of DNA barcoding in the radiation of the freshwater stingray genus Potamotrygon (Potamotrygonidae, Myliobatiformes)
A phylogenetic analysis of the family Potamotrygonidae based on mitochondrial cytochrome c oxidase I gene suggests that the family passed through a process of rapid speciation and that the species PotamOTrygon motoro, P. scobina, and P. orbignyi share haplotypes extensively.
DNA barcoding Australasian chondrichthyans: results and potential uses in conservation
It is concluded that cox1 barcoding can be used to identify shark and ray species with a very high degree of accuracy and also highlights some taxonomic issues that need to be investigated further.
Molecular barcoding of north-east Atlantic deep-water sharks: species identification and application to fisheries management and conservation
This is the first attempt to test the suitability of using a DNA barcode approach to discriminate accurately among the four most important commercial deep-water shark species, and Amplification of the COI gene coupled with MboI restriction digests was found to be a fast and inexpensive strategy to resolve within genera identification problems.
Mitochondrial gene sequences useful for species identification of western North Atlantic Ocean sharks
DNA sequence variation of a 1.4-kb region from the mitochondrial genome covering partial sequences from the 12S r DNA, 16S rDNA, and the complete valine tRNA from 35 shark species from the Atlantic fishery indicates that this locus is suitable for species identification.
Elasmobranch Phylogeny: A Mitochondrial Estimate Based on 595 Species
Interest in elasmobranch biodiversity and taxonomy has grown in recent years, catalyzed primarily by four influences: (1) the large number of new species that have been described over the past 30
Mitochondrial DNA supports the identification of two endangered river sharks (Glyphis glyphis and Glyphis garricki) across northern Australia
Nine species-specific nucleotide differences were found between G. glyphis and G. garricki and no intra-specific variation provides strong support for the separation into distinct species, with Glyphis forming a distinct clade from Carcharhinus.
