Sphyrna alleni sp. nov., a new hammerhead shark (Carcharhiniformes, Sphyrnidae) from the Caribbean and the Southwest Atlantic.

Zootaxa
Hammerhead sharks (Family Sphyrnidae) comprise a monophyletic Miocene radiation of carcharhiniform sharks characterized by their laterally expanded and dorsoventrally compressed head ('cephalofoil').

The appendicular skeleton of the enigmatic shark Leptocharias smithii in comparison with other sharks of the order Carcharhiniformes (Elasmobranchii: Leptochariidae)

Journal of morphology
Leptocharias smithii has been poorly explored in anatomical terms. This species bears a mosaic of morphological characters and is considered to represent an intermediate condition between other carcharhiniform clades. In the present paper, the anatomy of

Biological observations on the broadfin shark Lamiopsis temminckii (Carcharhiniformes: Carcharhinidae)

Journal of Fish Biology, 2017
Biological information was collected from 214 individuals of the broadfin shark Lamiopsis temminckii measuring 418 to 1782 mm total length, LT. Size at maturity (L50) for females and males was estimated at 1430 and 1368 mm LT, respectively, while mature and gravid females were observed from 1350 mm LT with litter sizes 2–8 and size at birth 418–650 mm ...

Complete mitogenome of the Graceful Shark Carcharhinus amblyrhynchoides (Carcharhiniformes: Carcharhinidae)

Mitochondrial DNA Part A, 2014
In this manuscript we describe the first complete mitochondrial sequence for the Near Threatened Graceful Shark Carcharhinus amblyrhynchoides. It is 16,705 bp in length, consists of two rRNA genes, 22 tRNA genes, 13 protein-coding genes and one control region with the typical gene arrangement pattern and translate orientation in vertebrates.

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

Description of the chondrocranium of the silky shark Carcharhinus falciformis with comments on the cranial terminology and phylogenetic implications in carcharhinids (Chondrichthyes, Carcharhiniformes, Carcharhinidae)

Journal of morphology, 2021
The definition and scope of the genus Carcharhinus has undergone several changes over the years and recent molecular studies have questioned its monophyly by the inclusion of other carcharhinid genera.

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.

Aspects of the biology of carcharhiniform sharks in Indonesian waters

Journal of the Marine Biological Association of the United Kingdom, 2007
A total of 13 species of carcharhiniform sharks (excluding the families Carcharhinidae and Sphyrnidae) belonging to four families was recorded in fish landing site surveys in eastern Indonesia. Of these, the Triakidae were most abundant in the landings with Hemitriakis sp. 1 and Mustelus cf.

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

A new genus of Phyllobothriidae (Cestoda: Tetraphyllidea) in carcharhiniform sharks from Iran and Australia

Journal of Helminthology, 2010
AbstractThe collection of cestodes from the carcharhiniform shark Carcharhinus cf. dussumieri in the Persian Gulf off Iran resulted in the discovery of the new genus and species of tetraphyllidean tapeworm, Doliobothrium haselii n. gen. n. sp. Collections from the carcharhiniform shark Rhizoprionodon acutus in the Timor Sea off northern Australia ...
