Characterization of the complete mitochondrial genome of blacktip shark Carcharhinus limbatus (Carcharhiniformes: Carcharhinidae). [PDF]

Mitochondrial DNA B Resour, 2022
In this study, we aimed to determine the complete mitochondrial genome of blacktip shark Carcharhinus limbatus. The mitochondrial genome was 16,705 bp in length, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region ...

Ion Torrent data for the genome assembly and phylogenomic placement of mitochondrial genomes with a focus on houndsharks (Chondrichthyes: Triakidae). [PDF]

Data Brief
Here, we present, for the first time, the Ion TorrentⓇ next-generation sequencing (NGS) data for five houndsharks (Chondrichthyes: Triakidae), which include Galeorhinus galeus (number of bases pairs (bp) 17,487; GenBank accession number ON652874 ...

Reappraisal of the extinct barbelthroat shark †Bavariscyllium and the nebulous origin of carcharhiniform galeomorphs. [PDF]

Commun Biol
We present a revised diagnosis of the extinct galeomorph shark †Bavariscyllium based on dental and skeletal material from the Upper Jurassic of Germany and test its purported carcharhiniform affinity through morphometric and phylogenetic analyses ...

Combining palaeontological and neontological data shows a delayed diversification burst of carcharhiniform sharks likely mediated by environmental change. [PDF]

Sci Rep, 2022
Estimating deep-time species-level diversification processes remains challenging. Both the fossil record and molecular phylogenies allow the estimation of speciation and extinction rates, but each type of data may still provide an incomplete picture of ...

Phylogeny explains capture mortality of sharks and rays in pelagic longline fisheries: a global meta-analytic synthesis. [PDF]

Sci Rep, 2022
Apex and mesopredators such as elasmobranchs are important for maintaining ocean health and are the focus of conservation efforts to mitigate exposure to fishing and other anthropogenic hazards.

Extensive MHC class IIβ diversity across multiple loci in the small-spotted catshark (Scyliorhinus canicula). [PDF]

Sci Rep, 2023
The major histocompatibility complex (MHC) is a multigene family responsible for pathogen detection, and initiation of adaptive immune responses. Duplication, natural selection, recombination, and their resulting high functional genetic diversity spread ...

Three-dimensional fossils of a Cretaceous collared carpet shark (Parascylliidae, Orectolobiformes) shed light on skeletal evolution in galeomorphs. [PDF]

R Soc Open Sci
A rich fossil record of teeth shows that many living shark families’ origins lie deep in the Mesozoic. Skeletal fossils of the sharks to whom these teeth belonged are far rarer and when they are preserved are often flattened, hindering understanding of ...
