A collection of nine shark specimens from six different species, obtained in 1993 from the Gulf of Thailand, was examined in this study. The sharks were determined, morphometrically and meristically analyzed, photographically documented, and compared with relevant literature. Additionally, further available material from the fish collections of the Zoological Museum Hamburg, the Senckenberg Naturmuseum Frankfurt, and the Museum national d’Histoire naturelle, Paris, was examined by way of… 
Taxonomic assessment of sharks, rays and guitarfishes (Chondrichthyes: Elasmobranchii) from south-eastern Arabia, using the NADH dehydrogenase subunit 2 (NADH2) gene
TLDR
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.
Annotated checklist of the living sharks, batoids and chimaeras (Chondrichthyes) of the world, with a focus on biogeographical diversity.

TLDR
This checklist represents the first global checklist of chondrichthyans to include information on maximum size, geographic and depth distributions, as well as comments on taxonomically problematic species and recent and regularly overlooked synonymizations.
New specimen of the rare requiem shark Eogaleus bolcensis from the Bolca Lagerstätte, Italy.
A rare carcharhinid specimen (slab and counter-slab, MSNPV 24625-24626) from the world-renowned Eocene Bolca locality was recently rediscovered during a restoration project started in 1989 by the
Redescription of Paragaleus tengi (Chen, 1963) (Carcharhiniformes: Hemigaleidae) and first record of Paragaleus randalli Compagno, Krupp & Carpenter, 1996 from the western North Pacific.
TLDR
The presence of Paragaleus randalli from off Taiwan in the western North Pacific is confirmed and the conservation status of these two species needs to be reassessed based on this new information.
Annotated checklist of the fishes of the Persian Gulf: Diversity and conservation status
TLDR
This checklist aims to reviews and summarize the results of the systematic researches on the Persian Gulf ichthyofauna that has been carried out for more than 200 years based on literature and taxon occurrence data obtained from natural history and new fish collections.
Carcharhinus humani sp. nov., a new whaler shark (Carcharhiniformes:Carcharhinidae) from the western Indian Ocean.
A new species of whaler shark, Carcharhinus humani sp. nov., is described based on five type specimens from the western Indian Ocean near the Socotra Islands, off Kuwait, Mozambique, and South
New records of sharks (Elasmobranchii) from the Andaman and Nicobar Archipelago in India with notes on current checklists
TLDR
Reports on shark species examined during fish landing surveys conducted from January 2017 to April 2018 increase the reported shark species for the Andaman and Nicobar Archipelago from 47 to 59 and for India from 114 to 116.
Catch composition and aspects of the biology of sharks caught by Thai commercial fisheries in the Andaman Sea.
TLDR
The results from this study emphasize the urgency for additional research and monitoring efforts and also the need for management incentives in order to manage shark fisheries effectively in the Andaman Sea.
Population Status of Two Wedgefish Species in Western Indonesian Inner Waters, Inferred from Demographic Models with Limited Data
Wedgefish (family Rhinidae) is a group of elasmobranchs that experience a global threat due to its highly valued fins. Similar condition happens to most species of wedgefish inhabiting Indonesian

Elasmobranchs of the Persian (Arabian) Gulf: ecology, human aspects and research priorities for their improved management
  • A. Moore
  • Environmental Science
    Reviews in Fish Biology and Fisheries
  • 2011
TLDR
Priorities for research in the near future should include: resolution of taxonomic issues; species-level monitoring and reporting of fisheries landings by all Gulf states; establishing the degree of connectivity of Gulf populations to those in adjacent waterbodies; and identification of key spatio-temporal sensitivities.
Inter‐ and intraspecific variation in the distribution and number of pit organs (free neuromasts) of sharks and rays
  • M. Peach

    Journal of morphology
  • 2003
TLDR
All of the species examined here had few pit organs compared to the pelagic sharks previously documented, but it is not clear whether this is due to ecological or phylogenetic causes.
The effects of fishing on sharks, rays, and chimaeras (chondrichthyans), and the implications for marine ecosystems
TLDR
The effects of fishing on sharks, rays, and chimaeras (chondrichthyans), and the implications for marine ecosystems are examined at the single-species level and through trophic interactions.
Identification of Shark Species Composition and Proportion in the Hong Kong Shark Fin Market Based on Molecular Genetics and Trade Records
TLDR
This work designed a sampling strategy for collecting statistically sufficient numbers of fins from traders and categories under conditions of limited market access because of heightened trader sensitivities, and incorporated the concordance information and available market auction records for these categories into stochastic models to estimate the contribution of each taxon by weight to the fin trade.
Identifying sharks with DNA barcodes: assessing the utility of a nucleotide diagnostic approach
TLDR
The results demonstrate that a character‐based, nucleotide diagnostic (ND) approach to barcode identification is feasible and also provides novel insights into the structure of haplotype diversity among closely related species of sharks.
Sharks and their Relatives: Ecology And Conservation
TLDR
The widely-acknowledged need to improve shark fishery monitoring, expand biological research and take management action is emphasized, with the introduction of new conservation and management initiatives.
Rapid worldwide depletion of predatory fish communities
TLDR
The analysis suggests that management based on recent data alone may be misleading, and provides minimum estimates for unexploited communities, which could serve as the 'missing baseline' needed for future restoration efforts.

Global estimates of shark catches using trade records from commercial markets.
TLDR
The results provide the first fishery-independent estimate of the scale of shark catches worldwide and indicate that shark biomass in the fin trade is three to four times higher than shark catch figures reported in the only global data base.
