Environmental DNA Reveals Distinct Regions of Extraordinary Marine Biodiversity to Inform a Newly Established Marine Park—Exmouth Gulf, Western Australia

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Exmouth Gulf, Western Australia, is a globally significant refuge for many marine megafauna species. The recent designation of a marine park in Exmouth Gulf underscores its environmental, social and cultural significance but remains a site of competing interests.

Dental Morphology, Palaeoecology and Palaeobiogeographic Significance of a New Species of Requiem Shark (Genus Carcharhinus) from the Lower Miocene of Peru (East Pisco Basin, Chilcatay Formation)

Journal of Marine Science and Engineering, 2022
Nowadays, the requiem sharks comprise one of the most diverse and widespread families of selachians, i.e., Carcharhinidae. Among the carcharhinids, the genus Carcharhinus has the largest number of living species, namely, at least 35.

Citizen Science for Sharks and Rays: Evaluating iNaturalist Records to Document Elasmobranch Diversity and Occurrence in the Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Elasmobranchs in the Mediterranean Sea face intense human‐induced pressures, with nearly half of their populations at risk of extinction. Overexploitation, limited data availability, lack of international cooperation and uneven public awareness hinder effective management.

Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

Journal of Fish Biology, Volume 108, Issue 6, Page 2053-2068, June 2026.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

Geographical Variation in Body Size and Sexual Size Dimorphism (SSD) in the Epaulette Shark (Hemiscyllium ocellatum)

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim Body size is of paramount importance to the survival of all organisms because of the intimate associations between size, physiological processes and ecology. Sexual size dimorphism (SSD: differences in size between the sexes) is a direct consequence of these ecomorphological relationships, arising due to sex‐based differences in selection ...

Ecological function of the Ariake Bay as a scalloped hammerhead shark (Sphyrna lewini) nursery in the northwestern Pacific

Global Ecology and Conservation
The scalloped hammerhead (Sphyrna lewini), a cosmopolitan shark inhabiting temperate and tropical waters, is highly vulnerable to fisheries owing to late maturity and low reproductive output.
