Panbiogeographical analysis of the shark genus Rhizoprionodon (Chondrichthyes, Carcharhiniformes, Carcharhinidae)

Journal of Fish Biology, 2010
The distributional patterns of the seven species of Rhizoprionodon were analysed using the panbiogeographical method of track analysis. The individual tracks of Rhizoprionodon suggest that the genus is mainly an Indian–Atlantic Ocean group. Five generalized tracks were found: (1) Caribbean, defined by R. porosus and R. terraenovae; (2) eastern coast of

Mitochondrial genome of the bull sharkCarcharhinus leucas(Carcharhiniformes: Carcharhinidae)

Mitochondrial DNA, 2014
The bull shark Carcharhinus leucas is a large elasmobranch species widespread in tropical and warm oceans, rivers and lakes. We first determine the complete mitogenome of C. leucas in this article. It is 16,704 bp in length, consists 37 genes and one control region with the typical gene order in vertebrates. The ND6 gene used the rare AGG as stop codon.

Caudal musculature in ground sharks, Carcharhiniformes, with remarks on their phylogenetic interrelationships

Journal of Morphology, 2018
AbstractRelationships among families of the shark order Carcharhiniformes are still being debated, for example, in relation to the inclusion of hammerhead sharks (Sphyrnidae) and the tiger shark (Galeocerdo cuvier) in the Carcharhinidae. Previous morphological studies have not analyzed the phylogenetic significance of axial caudal muscles among ...

Genetic identification of lamniform and carcharhiniform sharks using multiplex-PCR

Conservation Genetics Resources, 2009
Nowadays, because of the constant increase in the capture and trade of sharks all over the world and reports of several species already showing important signs of over-exploitation, the establishment of registration mechanisms, evaluation and fishery control become urgent. Morphological identification of captured sharks is very difficult, and sometimes

Hemitriakis complicofasciata, a new whitefin topeshark (Carcharhiniformes: Triakidae) from Japan

Ichthyological Research, 2004
Hemitriakis complicofasciata sp. nov. is described from 18 specimens from the waters of the Ryukyu Islands, southern Japan. This new species is distinguishable from other congeners by the following characters: higher vertebral counts (46–52 monospondylous vertebrae and 124–131 precaudal total vertebrae), presence of a developed posterior nasal flap ...

Complete mitochondrial genome of the Spadenose shark Scoliodon laticaudus (Carcharhiniformes: Carcharhinidae)

Mitochondrial DNA Part A, 2015
The complete mitochondrial genome of the Spadenose shark Scoliodon laticaudus has been determined for the first time in this study. It was 16,695 bp in length and consisted of 37 genes with typical gene order in vertebrate mitogenome. The nucleotide base content of S. laticaudus mitogenome was 31.5% A, 23.7% C, 13.2% G and 31.6% T.

Mitochondrial genome of the spot-tail sharkCarcharhinus sorrah(Carcharhiniformes: Carcharhinidae)

Mitochondrial DNA, 2014
In this article, we first presented the complete mitogenome of the spot-tail shark Carcharhinus sorrah, which is a medium-sized shark distributed in the tropical Indo-Pacific and is currently listed as "Near Threatened" on the International Union for Conservation of Nature (IUCN) Red List. The complete mitogenome of C. sorrah is 16,707 bp in length and

Complete mitochondrial genome of the Pigeye Shark Carcharhinus amboinensis (Carcharhiniformes: Carcharhinidae)

Mitochondrial DNA Part A, 2014
In this manuscript we describe the first complete mitochondrial sequence for the Data Deficient Pigeye Shark Carcharhinus amboinensis. The mitogenome is 16,704 bp long and consists of 1 control region, 2 rRNA genes, 22 tRNA genes and 13 protein-coding genes with an overall base composition of 31.6% A, 24.9% C, 13.1% G and 30.4% T.
