Comparison of Physicochemical and Structural Properties of Acid-Soluble and Pepsin-Soluble Collagens from Blacktip Reef Shark Skin [PDF]

Marine Drugs, 2022
Fish collagen has been widely used in tissue engineering (TE) applications as an implant, which is generally transplanted into target tissue with stem cells for better regeneration ability.

Sex-based differences in movement and space use of the blacktip reef shark, Carcharhinus melanopterus. [PDF]

PLoS ONE, 2020
Information on the spatial ecology of reef sharks is critical to understanding life-history patterns, yet gaps remain in our knowledge of how these species move and occupy space.

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.

Microbothriid (Monogenean) Infection and Treatment in Captive Blacktip Reef Shark (Carcharhinus melanopterus) [PDF]

Microorganisms
Unlike other microbothriid monogenean infections in elasmobranchs, limited information is available on the biology and treatment of Dermophthirius melanopteri. As parasitic infection with D.

Environmental and Protection Effects of Shark-Companion Associations Across Three Ocean Basins. [PDF]

Ecol Evol
Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.

Inferring leader-follower dynamics in three shark species using acoustic telemetry data [PDF]

Movement Ecology
Background Understanding collective behaviours and interactions in sharks is still in its infancy. Although recent studies have revealed some social structures in several shark species, little is known about complex interactions and social processes such

Behaviour of mesopredatory coral reef fishes in response to threats from sharks and humans [PDF]

Scientific Reports, 2023
Both sharks and humans present a potentially lethal threat to mesopredatory fishes in coral reef systems, with implications for both population dynamics and the role of mesopredatory fishes in reef ecosystems.

Defining ecological roles of sharks on coral reefs. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Sharks have often been perceived to play a critical role in the dynamics of coral reef ecosystems globally. Yet, there is relatively little evidence to support this idea across all but a limited set of species and contexts. Research on the roles and importance of reef sharks has been complicated by logistical challenges in collecting data on ...

Trouble in the Tank: A Case Report of Fatal Scuticociliate Encephalitis in a Whitetip Reef Shark (Triaenodon obesus). [PDF]

J Fish Dis
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.

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean. [PDF]

J Fish Biol
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.
