Thermal tolerance and hypoxia tolerance are associated in blacktip reef shark (Carcharhinus melanopterus) neonates [PDF]

Journal of Experimental Biology, 2020
ABSTRACT Thermal dependence of growth and metabolism can influence thermal preference and tolerance in marine ectotherms, including threatened and data-deficient species. Here, we quantified the thermal dependence of physiological performance in neonates of a tropical shark species (blacktip reef shark, Carcharhinus melanopterus) from ...

Defining distribution and habitat use of west‐central Florida’s coastal sharks through a research and education program

Ecology and Evolution, 2021
Identifying critical habitat for highly mobile species such as sharks is difficult, but essential for effective management and conservation. In regions where baseline data are lacking, non‐traditional data sources have the potential to increase ...

Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity. [PDF]

J Anat
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

On the Movements of the Blacktip Reef Shark (Carcharhinus melanopterus)

, 2023
One challenge in studying the natural behaviour of wild animals is the requirement of detailed observations spanning extended periods of time, which is particularly difficult in the case of sharks. As a result, remote sensing technologies are increasingly employed in which the data received is considerably simplified.

Vulnerability of tropical fish communities across depth in the central Indian Ocean. [PDF]

Conserv Biol
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Human‐induced shifts in habitat use and behaviour of a marine predator: the effects of bait provisioning in the blacktip reef shark [PDF]

Animal Conservation, 2020
AbstractWhile the negative effects of consumptive pressures on marine predators are well established, the effects of increasing non‐consumptive activities such as wildlife tourism are still understudied. As such, the long‐term effects of the provision of bait on shark behaviour are still unclear.

Blacktip Reef Shark Aggression in Moorea v1

, 2023
On the island of Moorea, French Polynesia, tourism operators have engaged in consistent elasmobranch provisioning at specific sites since the 1990s, conditioning the area’s shark and ray populations to human feeding and developing profitable lagoon tours based on close-contact elasmobranch encounters.

First record of the blacktip reef shark Carcharhinus melanopterus (Carcharhiniformes: Carcharhinidae) from the Tropical Eastern Pacific

Revista de Biología Tropical, 2012
The blacktip reef shark Carcharhinus melanopterus, is one of the most common Indo-Pacific reef sharks. On April 29, 2012, a juvenile male blacktip reef shark measuring 89 cm total length (TL), was incidentally caught during a research expedition in ...
