Marine‐Derived Type I Collagen From Scyliorhinus canicula: Extraction, Characterization, and Biomedical Applications

Journal of Applied Polymer Science, EarlyView.
Marine‐derived type I collagen is extracted from Scyliorhinus canicula skin and characterized by physicochemical and morphological analyses. The collagen exhibits excellent biocompatibility, promotes wound healing, reduces inflammatory mediators, and inhibits melanogenesis.

Regional hotspots and drivers of shark meat consumption in India

Conservation Science and Practice
Over one third of shark and ray (henceforth elasmobranch) species are threatened by global extinction. Overfishing, driven largely by human consumption of various products is a key threat to >95% of threatened elasmobranch species.

Spatial heterogeneity in fishing creates de facto refugia for endangered Celtic Sea elasmobranchs. [PDF]

PLoS ONE, 2012
The life history characteristics of some elasmobranchs make them particularly vulnerable to fishing mortality; about a third of all species are listed by the IUCN as Threatened or Near Threatened.

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Fishers' interactions with endangered “rhinorays” in Karimunjawa National Park, and factors influencing willingness to engage in pro‐conservation behavior

Conservation Science and Practice
The “rhinorays” (giant guitarfish‐Glaucostegidae and wedgefish‐Rhinidae) are a critically endangered group of “shark‐like rays,” which have experienced steep global population declines in the past decade due to overfishing.

A Long-Term Overview of Elasmobranch Fisheries in an Oceanic Archipelago: A Case Study of the Madeira Archipelago

Fishes
Elasmobranch species are considered a global conservation priority due to their susceptibility to fishing pressure. In the Madeira Archipelago, Northeastern Atlantic, most elasmobranch species are caught as bycatch in artisanal drifting longline fishery ...

Addressing data-deficiency of threatened sharks and rays in a highly dynamic coastal ecosystem using environmental DNA

Ecological Indicators, 2023
Marine biodiversity loss is accelerating, leading to the elevated extinction risks of many species, including sharks and rays. To mitigate these losses, information on their distribution and community composition is needed.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Elasmobranch bycatch distributions and mortality: Insights from the European tropical tuna purse-seine fishery

Global Ecology and Conservation, 2020
Despite bycatch of elasmobranch (sharks and rays) being a major concern in most fisheries worldwide, there is a lack of knowledge on their spatio-temporal species distribution, biology (life stage and sex-ratios), as well as their at-haulback mortality ...
