It makes a difference who you are: first record of Dasyatis tortonesei Capapé, 1975 along Sardinian coasts and taxonomic uncertainties within stingrays

The European Zoological Journal
Despite several records of Dasyatis tortonesei Capapé, 1975 in the Mediterranean Sea, its distribution and abundance have been questioned due to the cryptic nature of the Tortonese’s stingray and the frequent misidentification with the common stingray ...

Morphological and molecular insights into diversity of Brevitrygon (Elasmobranchii, Myliobatiformes, Dasyatidae) in Thai waters [PDF]

Acta Ichthyologica et Piscatoria
Stingrays of the genus Brevitrygon in Thailand are captured as bycatch in fisheries, and a proportion of the catch is used for local consumption, but information on their biodiversity remains limited.

The description of two new species of Chloromyxum from skates in the Argentine Sea reveals that a limited geographic host distribution causes phylogenetic lineage separation of myxozoans in Chondrichthyes

Parasite, 2018
During a survey on the myxosporean fauna of Rajiformes from the Atlantic coast of Argentina, in waters off Buenos Aires Province (34°–42°S; 53°–62°W), the gall bladders of 217 specimens belonging to seven species of skates, representatives of two ...

Fisher perceptions of catch and trade of sharks and rays in Angolan small‐scale fisheries

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 5, May 2024.
Abstract Small‐scale fisheries ensure food security and employment in Angolan coastal communities. These dynamic, widespread fisheries remain mostly unregulated, with limited data available despite their likely significant impact on marine megafauna. We used an interview‐based survey to investigate local fisher interactions with elasmobranchs (sharks ...

Comparative assessment of eDNA metabarcoding and longline deployments for elasmobranch surveying across a large tropical marine park network

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 4, April 2024.
Abstract Medium‐ to large‐scale marine protected areas (MPAs) are playing an increasingly important role in global marine biodiversity conservation. A key question is “how do we collect relevant data on biodiversity and population trends to inform their design and measure success?” This question is particularly relevant for marine taxa that are ...

An unusual, dwarf new species of Neotropical freshwater stingray, Plesiotrygon nana sp. nov., from the upper and mid Amazon basin: the second species of Plesiotrygon (Chondrichthyes: Potamotrygonidae)

Papéis Avulsos de Zoologia, 2011
A new species of the relatively poorly known Neotropical freshwater stingray genus Plesiotrygon Rosa, Castello & Thorson, 1987 is described from the main channel and smaller tributaries (Ríos Itaya and Pachitea) of the upper Amazon basin in Peru.

Venom gland transcriptome analyses of two freshwater stingrays (Myliobatiformes: Potamotrygonidae) from Brazil

Scientific Reports, 2016
AbstractStingrays commonly cause human envenoming related accidents in populations of the sea, near rivers and lakes. Transcriptomic profiles have been used to elucidate components of animal venom, since they are capable of providing molecular information on the biology of the animal and could have biomedical applications.
