The elasmobranchs (sharks, rays and skates) being the extant survivors of one of the earliest offshoots of the vertebrate evolutionary tree are good model organisms to study the primitive vertebrate conditions. They play a significant role in maintaining the ecological balance and have high economic value. Due to over-exploitation and illegal fishing worldwide, the elasmobranch stocks are being decimated at an alarming rate. Appropriate management measures are necessary for restoring depleted…

Molecular Phylogeny of Elasmobranchs

This chapter summarizes the phylogeny studies reported on elasmobranchs and highlights the significance of molecular phylogeny in resolving taxonomic uncertainties and providing insights into the evolutionary relationship among elasmOBranchs.

Mitogenomics of electric rays: evolutionary considerations within Torpediniformes (Batoidea; Chondrichthyes)

The phylogenetic analyses support the hypothesis that electric rays are closely related to thornback rays (Platyrhinidae), forming a clade in a sister position to a group containing the remaining three batoid orders.

A Review of the Mitogenomic Phylogeny of the Chondrichthyes

The phylogenetic trees generated rejected the “Hypnosqualea” hypothesis and confirmed the monophyly of the Neoselachii and Batoidea as sister groups of the sharks.

Complete Mitochondrial DNA Genome of Nine Species of Sharks and Rays and Their Phylogenetic Placement among Modern Elasmobranchs

The present study expands the knowledge on the systematics, genetic differentiation, and conservation genetics of the species studied, and contributes to the understanding of the evolutionary history of Chondrichthyes.

Introductory Chapter: The Elasmobranchs as a Fishery Resource

However, the full diversity of the elasmobranchs is still unclear, and a number of species have been described in recent years, principally from the waters of Asia and Oceania [5–8]. In one of the…

DNA Barcoding and Molecular Phylogeny

The significance and utility of DNA barcoding in various fields is discussed, including biodiversity assessment, life history and ecological studies, forensic analysis, and many more.

Delimiting cryptic species within the brown-banded bamboo shark, Chiloscyllium punctatum in the Indo-Australian region with mitochondrial DNA and genome-wide SNP approaches

It is found that SNP data provided more robust results than mtDNA data in determining the boundary between population and cryptic species, and it is recommended that future studies use a comprehensive sampling regime that encompasses the full range of a species complex.

Phylogenetic significance of clasper morphology of electric rays (Chondrichthyes: Batoidea: Torpediniformes)

The present article analyzes the external and skeletal clasper anatomy of electric rays and reports newly discovered characters that can be useful for taxonomic diagnoses and higher‐level systematic studies.

Molecular phylogenetic inference of White-Spotted Guitarfish (Rhynchobatus australiae) collected from local Malaysian fish markets

This study has proven the efficiency of the COI mitochondrial locus in revealing the phylogenetic position of R. australiae and increased the understanding of the phylogenetically relationships among guitarfish, sharks, and rays, and their respective taxonomic positions are given their shared morphological characters.

Revision of the fossil batomorphs from the Cretaceous of Lebanon, and their impact on our understanding of the early step of the evolution of the clade

The attribution of three lebanese shark-like rhinobatids species included into two new genera to Rhynchobatidae are discussed, which possess a combination of primitive characters such as propterygium failing to reach the level of the nasal capsules and pectoral fin posterior corner not reaching thelevel of the pelvic fin.
