A new redescription of Galeus atlanticus (Vaillant, 1888) (Chondrichthyes: Scyliorhinidae) based on field marks [PDF]

open access: yes, 2006
The Atlantic sawtail catshark, Galeus atlanticus, has long been synonymous with the blackmouth catshark, Galeus melastomus, until the validity of G. atlanticus was resurrected by Muñoz-Chapuli and Ortega (1985).

Genome‐wide identification and solute selectivity of aquaporins in the sharpnose sevengill shark, Heptranchias perlo

open access: yesPhysiological Reports, Volume 14, Issue 8, April 2026.
Abstract The aquaporin genes (aqps) are widely distributed among vertebrates. In cartilaginous fish, aqp3 and aqp10 are duplicated, whereas many species have lost aqp8. While the solute permeability of aquaglyceroporins and Aqp8 exhibits significant diversity, systematic evaluations of their activity within species are limited.

Increasing the data on elasmobranch plasma protein electrophoresis: electrophoretogram reference values determination in the undulate skate (Raja Undulata) and the nursehound shark (Scyliorhinus stellaris) maintained under human care

open access: yesBMC Veterinary Research, 2022
Background This study determined plasma protein electrophoresis (PPE) reference intervals in two elasmobranch species: the undulate skate (Raja undulata) and the nursehound shark (Scyliorhinus stellaris), using a reference population of 48 undulate ...

Comparison of Environmental DNA Metabarcoding and Trawl Data Highlights Gear Selectivity of Marine Demersal Fish Surveys on the Faroese Plateau

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
The study compared trawl and eDNA metabarcoding of demersal fish communities in an open ocean environment around the Faroe Islands. eDNA provided a comparable assessment of demersal species biomass and revealed additional spatial information on keystone species known to be under‐sampled by demersal trawls due to size and behavioral traits.

Seascape Genomics Uncovers Genomic Patterns Shaped by Temperature and Salinity Outlier Loci in Dolphinfish (Coryphaena hippurus Linnaeus, 1758) Across the Atlantic Ocean and Mediterranean Sea

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT In this study, we explored the population genetic structure and its relation to environmental adaptations of the dolphinfish (Coryphaena hippurus) in the western Atlantic Ocean and Mediterranean Sea. Although previously two populations within the Mediterranean Sea were identified, recent evidence suggests more complex structuring.

Regional variability in the trophic requirements of shelf sea fisheries in the Northeast Atlantic, 1973-2000 [PDF]

open access: yes, 2005
Hydrographic, plankton, benthos, fisheries landings, and fish diet data from shelf sea areas in the Northeast Atlantic have been combined into an analysis of the foodweb structure and secondary production requirements of regional fisheries. Fish landings

The Shark Basal Hypothalamus: Molecular Prosomeric Subdivisions and Evolutionary Trends

open access: yesFrontiers in Neuroanatomy, 2018
The hypothalamus is a key integrative center of the vertebrate brain. To better understand its ancestral morphological organization and evolution, we previously analyzed the segmental organization of alar subdivisions in the catshark Scyliorhinus ...
