Response of blacktip reef sharks Carcharhinus melanopterus to shark bite mitigation products [PDF]
Scientific Reports, 2020 AbstractGlobally, the frequency of shark bites is rising, resulting in an increasing demand for shark deterrents and measures to lessen the impact of shark bites on humans. Most existing shark protection measures are designed to reduce the probability of a bite, but fabrics that minimise injuries when a shark bite occurs can also be used as mitigation ...

Genetic evidence for plastic reproductive philopatry and matrotrophy in blacktip reef sharks (Carcharhinus melanopterus) of the Moorea Island (French Polynesia) [PDF]
Scientific Reports, 2023 The exploitation of sharks and the degradation of their habitats elevate the urgency to understand the factors that influence offspring survival and ultimately shark reproductive success.

Quantifying changes in umbilicus size to estimate the relative age of neonatal blacktip reef sharks (Carcharhinus melanopterus) [PDF]
Conservation Physiology, 2023 ABSTRACT Sharks can incur a range of external injuries throughout their lives that originate from various sources, but some of the most notable wounds in viviparous shark neonates are at the umbilicus. Umbilical wounds typically heal within 1 to 2 months post-parturition, depending on the species, and are therefore often used as an ...

Blacktip reef sharks (Carcharhinus melanopterus) show high capacity for wound healing and recovery following injury [PDF]
Conservation Physiology, 2015 Wound healing is important for sharks from the earliest life stages, for example, as the 'umbilical scar' in viviparous species heals, and throughout adulthood, when sharks can incur a range of external injuries from natural and anthropogenic sources. Despite anecdotal accounts of rapid healing in elasmobranchs, data regarding recovery and survival of ...

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean [PDF]
Journal of Fish Biology, Volume 108, Issue 4, Page 1347-1360, April 2026.Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

Observations of sharks (Elasmobranchii) at Europa Island, a remote marine protected area important for shark conservation in the southern Mozambique Channel. [PDF]
PLoS ONE, 2021 Sharks have declined worldwide and remote sanctuaries are becoming crucial for shark conservation. The southwest Indian Ocean is a hotspot of both terrestrial and marine biodiversity mostly impacted by anthropogenic damage.

Potential metabolic records in isotope signals of chondrichthyan hard tissues [PDF]
Journal of Fish Biology, Volume 107, Issue 3, Page 1001-1017, September 2025.Abstract Recent advances have demonstrated that the field metabolic rates (FMRs) of teleost fishes can be quantified from stable isotope compositions of carbonate‐biomineralized otoliths. Bones and teeth, in addition to bioapatite, contain carbonate and should retain a similar isotopic expression of metabolic rate.

Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity [PDF]
Journal of Anatomy, Volume 247, Issue 5, Page 924-952, November 2025.This study investigates the morphology, abundance, and distribution of taste papillae in the oropharyngeal cavity of a range of elasmobranchs using SEM, histology, and topographic analyses. The interspecific importance of gustation is reflected in quantitative differences in the size, density, and distribution of taste papillae, which have implications

Trouble in the Tank: A Case Report of Fatal Scuticociliate Encephalitis in a Whitetip Reef Shark (Triaenodon obesus) [PDF]
Journal of Fish Diseases, Volume 49, Issue 3, March 2026.Abstract This case report presents a recent case of scuticociliatosis in a whitetip reef shark (Triaenodon obesus), housed at a zoo (Haus des Meeres Aqua Terra Zoo, Vienna, Austria). Clinical signs such as uncoordinated swimming and body tilt were observed prior to death.

Genetic Diversity and Population Structure of Squalus cf. mitsukurii (Chondrichthyes: Squalidae) Revealed by ddRAD Sequencing [PDF]
Animal Genetics, Volume 57, Issue 2, April 2026.ABSTRACT Assessing genetic structure across ocean basins is essential to understand connectivity and guide conservation in data‐deficient open‐water sharks. In this study, we examined the population genomics of Squalus cf. mitsukurii by analyzing tissue samples collected from two distant regions: California, USA (Pacific Ocean) and Pernambuco, Brazil ...
