The Phenomenon of Piebaldism in Sharks: A Review of Global Sightings and Patterns. [PDF]

Ecol Evol
Chromatic disorders like piebaldism—a rare form of leucism causing partial pigment loss—have been documented in 25 wild shark cases across 17 species and 11 families, with varying anatomical distribution. This study compiles published and unpublished records to better understand the taxonomic and geographical spread of piebaldism and its potential ...

Potential metabolic records in isotope signals of chondrichthyan hard tissues. [PDF]

J Fish Biol
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.

A blacktip's black tip: The reliability of using dorsal-fin patterns for photo identification of blacktip reef sharks (Carcharhinus melanopterus). [PDF]

J Fish Biol
Abstract Photo identification (photo ID) has increasingly become a valuable technique serving not only to identify individual animals but also to monitor populations, track migration patterns and assess wildlife health, among others uses. Various species of sharks are amenable to photo ID, among which the blacktip reef shark (Carcharhinus melanopterus)

The risk assessment of Lead, Cadmium and Zinc in the two edible fishe species (Carcharhinus limbatus) and (Epinephelus coioides) of Persian Gulf in 2016 [PDF]

Pizhūhish dar Bihdāsht-i Muḥīṭ., 2018
Background and aim:With the development of coastal industries and cities, aquatic ecosystems and organisms are exposed to contaminants, especially heavy metals. Heavy metals accumulate in aquatic tissues and eventually enter the food chain and human body.

Secondary predation constrains DNA-based diet reconstruction in two threatened shark species

Scientific Reports, 2021
Increasing fishing effort, including bycatch and discard practices, are impacting marine biodiversity, particularly among slow-to-reproduce taxa such as elasmobranchs, and specifically sharks. While some fisheries involving sharks are sustainably managed,

In Situ Thrust Measurement of Fish During Locomotion; Test Case: Sharks. [PDF]

Ecol Evol
We present a novel method that uses in situ video data of fish locomotion to calculate thrust. This methodology was applied to several large elasmobranch species, which are typically challenging to measure. Our findings indicate that coastal pelagic species exhibited lower scaled thrust than benthic species, suggesting that benthic species may be less ...

Diet of the Blacktip Shark (Carcharhinus limbatus) in the Northwestern Gulf of Mexico

Gulf and Caribbean Research, 2020
The stomach contents of 90 Blacktip Shark (Carcharhinus limbatus) specimens caught in the northwestern Gulf of Mexico (GOM) were examined. Stomach contents were identified to the lowest possible taxon, and quantified using percent weight, percent number, percent frequency of occurrence, and percent index of relative importance (IRI).
