Whale carcass scavenging by sharks

Global Ecology and Conservation, 2019
Sharks are well known to scavenge whale carcasses, but observations are rare. Here we (1) describe new observations of whale carcass scavenging behaviour by white (Carcharodon carcharias) and tiger (Galeocerdo cuvier) sharks, and (2) review the ...

Dynamics of whale shark occurrence at their fringe oceanic habitat. [PDF]

PLoS ONE, 2014
Studies have shown that the whale shark (Rhincodon typus), a vulnerable large filter feeder, seasonally aggregates at highly productive coastal sites and that individuals can perform large, trans-boundary migrations to reach these locations.

Multi-Year Impacts of Ecotourism on Whale Shark (Rhincodon typus) Visitation at Ningaloo Reef, Western Australia. [PDF]

PLoS ONE, 2015
In-water viewing of sharks by tourists has become a popular and lucrative industry. There is some concern that interactions with tourists with ecotourism operations might harm sharks through disruption of behaviours. Here, we analysed five years of whale

Spatio-temporal patterns, trends, and oceanographic drivers of whale shark strandings in Indonesia [PDF]

Scientific Reports
Despite the increased international attention to whale shark conservation, their populations remain predominantly depleted due to anthropogenic activities such as fishing, ship collisions, and marine pollution.

The ecological connectivity of whale shark aggregations in the Indian Ocean: a photo-identification approach [PDF]

Royal Society Open Science, 2016
Genetic and modelling studies suggest that seasonal aggregations of whale sharks (Rhincodon typus) at coastal sites in the tropics may be linked by migration.

Whale Shark (Rhincodon typus) Seasonal Occurrence, Abundance and Demographic Structure in the Mid-Equatorial Atlantic Ocean. [PDF]

PLoS ONE, 2016
Whale sharks are generally associated with environmental factors that drive their movements to specific locations where food availability is high. Consequently, foraging is believed to be the main reason for the formation of whale shark aggregations ...

Satellite tracking of juvenile whale sharks in the Sulu and Bohol Seas, Philippines [PDF]

PeerJ, 2018
The whale shark Rhincodon typus was uplisted to ‘Endangered’ in the 2016 IUCN Red List due to >50% population decline, largely caused by continued exploitation in the Indo-Pacific. Though the Philippines protected the whale shark in 1998, concerns remain

The Needle in the Haystack: Uncovering the First Whale Shark (Rhincodon typus) Aggregation in the Coral Sea [PDF]

Ecology and Evolution
Aggregations are key events, supporting critical ecological and biological functions in many species. For highly mobile and elusive species, aggregations often provide the only feasible opportunities for research.

Long-term assessment of whale shark population demography and connectivity using photo-identification in the Western Atlantic Ocean. [PDF]

PLoS ONE, 2017
The predictable occurrence of whale sharks, Rhincodon typus, has been well documented in several areas. However, information relating to their migratory patterns, residency times and connectivity across broad spatial scales is limited.

Biomarkers of whale shark health: a metabolomic approach. [PDF]

PLoS One, 2012
In a search for biomarkers of health in whale sharks and as exploration of metabolomics as a modern tool for understanding animal physiology, the metabolite composition of serum in six whale sharks (Rhincodon typus) from an aquarium collection was explored using (1)H nuclear magnetic resonance (NMR) spectroscopy and direct analysis in real time (DART ...
