Illegal Trade in Protected Sharks: The Case of Artisanal Whale Shark Meat Fisheries in Java, Indonesia [PDF]

Animals, 2023
Illegal, unreported, and unregulated fishing, including that of sharks, poses a significant threat to marine ecosystems and individual species. I use data from the media, tourists, and artisan fishermen to gain insight into the trade in the world’s ...

In-water observations highlight the effects of provisioning on whale shark behaviour at the world's largest whale shark tourism destination [PDF]

Royal Society Open Science, 2020
The whale shark is the world's largest fish that forms predictable aggregations across its range, many of which support tourism industries. The largest non-captive provisioned whale shark destination globally is at Oslob, Philippines, where more than 500

Armored eyes of the whale shark. [PDF]

PLoS ONE, 2020
This report elaborates on adaptations of the eyes of the whale shark Rhincodon typus (Elasmobranchii, Rhincodontidae), including the discovery that they are covered with dermal denticles, which is a novel mechanism of eye protection in vertebrates.

Global collision-risk hotspots of marine traffic and the world's largest fish, the whale shark. [PDF]

Proc Natl Acad Sci U S A, 2022
Significance Global vessel traffic is increasing alongside world economic growth. The potential for rising lethal ship strikes on endangered species of marine megafauna, such as the plankton-feeding whale shark, remains poorly understood since areas of ...

Pieces in a global puzzle: Population genetics at two whale shark aggregations in the western Indian Ocean [PDF]

Ecology and Evolution, 2022
The whale shark Rhincodon typus is found throughout the world's tropical and warm‐temperate ocean basins. Despite their broad physical distribution, research on the species has been concentrated at a few aggregation sites.

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 ...

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.

Whale shark rhodopsin adapted to deep-sea lifestyle by a substitution associated with human disease. [PDF]

Proc Natl Acad Sci U S A, 2023
Spectral tuning of visual pigments often facilitates adaptation to new environments, and it is intriguing to study the visual ecology of pelagic sharks with secondarily expanded habitats.

Persistent Organic Pollutants in Whale Shark (Rhincodon typus) Skin Biopsies from Bahía de Los Ángeles, Mexico. [PDF]

Bull Environ Contam Toxicol, 2023
The whale shark ( Rhincodon typus ) is a filter-feeding organism that can be considered a sentinel species, and Bahía de los Ángeles (BLA) in the Gulf of California is an important sighting site for these elasmobranchs.

Emergent community architecture despite distinct diversity in the global whale shark (Rhincodon typus) epidermal microbiome. [PDF]

Sci Rep, 2023
Microbiomes confer beneficial physiological traits to their host, but microbial diversity is inherently variable, challenging the relationship between microbes and their contribution to host health.
