Extinction risk, reconstructed catches, and management of chondrichthyan fishes in the Western Central Atlantic Ocean
Chondrichthyan fishes are among the most threatened vertebrates on the planet because many species have slow life histories that are outpaced by intense fishing. The Western Central Atlantic Ocean,
Sixth sense in the deep-sea: the electrosensory system in ghost shark Chimaera monstrosa
Ampullary organs of the ghost shark Chimaera monstrosa, a deep-sea species commonly captured as by-catch in the bottom trawl fishery, are described for the first time using macroscopic, ultrastructural and histological approaches, showing some anatomical peculiarities never described before in others cartilaginous fishes.
The auditory system of cartilaginous fishes
Leopard Seals (Hydrurga leptonyx) in New Zealand Waters Predating on Chondrichthyans
Leopard seals (Hydrurga leptonyx) are top-order predators that prey on a wide variety of species including crustaceans, cephalopods, fishes, birds, and pinnipeds. While multiple diet studies have
Comparative Study of Semen Parameters and Hormone Profile in Small-Spotted Catshark (Scyliorhinus canicula): Aquarium-Housed vs. Wild-Captured
Evidence of good in vitro semen quality in S. canicula housed in an aquarium is provided, underlining their excellent potential for application in reproductive technologies for this and other chondrichthyan species.
State of Shark and Ray Genomics in an Era of Extinction
It is proposed that this field is in dire need to move forward quickly to increase protection for marine species and ecosystems through improved collaboration between marine, molecular, and computer sciences.
Chimaera compacta, a new species from southern Indian Ocean, and an estimate of phylogenetic relationships within the genus Chimaera (Chondrichthyes: Chimaeridae)
A new species of shortnose chimaera, described from a single specimen collected at 595–655 m depth, off Amsterdam Island, in the southern Indian Ocean, which has a nucleotide sequence divergence for the studied genes of 4.2 and 4.1% with its closest relatives.


Spatially congruent sites of importance for global shark and ray biodiversity
Low congruency is found among all three measures of species richness, with the threatened species comprising a smaller subset of the overall species patterns irrespective of hotspot definition, and evolutionarily distinct species richness had the highest overlap with total species richness regardless of resolution or definition of hotspots.
On the presence of the Eastern Pacific Black Ghostshark Hydrolagus melanophasma (Chondrichthyes: Chimaeridae) in northern Chile, with notes on its distribution in the Eastern Pacific
This work presents new records for this species based on specimens collected as bycatch in the Chilean Seabass, Dissostichus eleginoides Smith, 1898 fishery at a depth of 1800 m off Taltal (25°S), northern Chile, and reports the first record of a Gyrocotyle species as parasite in this species.
Trends in Chondrichthyan Research: An Analysis of Three Decades of Conference Abstracts
Given the conservation status and ecological, cultural, and commercial importance of chondrichthyan fishes, it is valuable to evaluate the extent to which research attention is spread across taxa and
Description and characterization of the artisanal elasmobranch fishery on Guatemala’s Caribbean coast
This study can serve as a baseline to determine future trends in the elasmobranch fisheries conducted by Guatemala’s Caribbean coastal communities and support assessments on the persistence of the fisheries.
Foreign Illegal, Unreported, and Unregulated Fishing in Somali Waters Perpetuates Conflict
Somali waters have the potential to support some of the most productive fisheries in the world, but the sustainability of those fisheries is compromised by the presence of foreign fishing vessels,
Reproductive biology of the cockfish , Canorhynchus callorhynchus ( Holocephali : Callorhynchidae ) , in Patagonian waters ( Argentina )
The data suggest that reproductive activities extend nearly throughout the year; mating and spawning occur in spring and early summer, followed by a short period lca.
Identification of essential habitats: Including chimaeras into current shark protected areas
1. Essential habitats are areas required to support specific functions, such as providing foraging grounds, shelter or used for reproductive purposes. For mobile aquatic species that move throughout
