Biofluorescence in Catsharks (Scyliorhinidae): Fundamental description and relevance for elasmobranch visual ecology [PDF]

, 2016
Biofluorescence has recently been found to be widespread in marine fishes, including sharks. Catsharks, such as the Swell Shark (Cephaloscyllium ventriosum) from the eastern Pacific and the Chain Catshark (Scyliorhinus retifer) from the western Atlantic,

Biodiversity and species-environment relationships of the demersal fish assemblage at the Great Meteor Seamount (subtropical NE Atlantic), sampled by different trawls [PDF]

, 2002
Quantitative data collected with different bottom trawls at the Great Meteor Seamount (subtropical NE Atlantic, 30°N; 28.5°W) in 1967, 1970 and 1998 are compared. Bootstrap estimates of total catch per unit effort increased from 6.96 and 10.8 ind.

Seasonal Changes of Fish Assemblages in a Subtropical Lagoon in the SE Gulf of California

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
The composition and seasonal changes of the fish assemblage in a coastal lagoon system in southeastern Gulf of California were assessed from December 2001 to July 2005. A total of 20,877 organisms belonging to 191 species and 47 families were analyzed. We determined that almost all the species inhabiting the system were found; however some rare species

First record of the electric ray Narcine leoparda (Batoidea: Torpediniforms: Narcinidae) in Ecuadorian waters

Marine Biodiversity Records, 2015
Six electric rays, Narcine leoparda, were caught off the coast of Manta, Ecuador between August 2013 and January 2014. These specimens represent the first record in Ecuadorian waters and the southernmost report in the eastern Pacific for the distribution of Narcine leoparda.

Earliest Danian outer neritic elasmobranch assemblages reveal an environmentally controlled faunal turnover at the Cretaceous–Palaeogene boundary in the northern Tethyan Realm (Austria)

Papers in Palaeontology, Volume 10, Issue 1, January/February 2024.
Abstract This study reports elasmobranch remains from two fossil‐rich horizons in the earliest Danian Olching Formation at Waidach, Austria. These outer neritic assemblages complement previous fine‐scale bulk‐sampling of latest Maastrichtian horizons at Waidach and document a regional elasmobranch faunal turnover across the Cretaceous–Palaeogene (K–Pg)

From historical expedition diaries to whole genome sequencing: A case study of the likely extinct Red Sea torpedo ray

Zoologica Scripta, Volume 53, Issue 1, Page 32-51, January 2024.
Abstract Torpedo rays (Torpedinidae, Torpediniformes) are small to moderately large batoids that produce an electric discharge. They are distributed worldwide in temperate and tropical seas and are, as a result of their bottom‐dwelling behaviour, susceptible to trawl fishing and often end up as victims of bycatch.
