Genetic Evidence of Killer Whale Predation on White Sharks in Australia [PDF]

Ecology and Evolution
Killer whales (Orcinus orca) have been documented to prey on white sharks (Carcharodon carcharias), in some cases causing localised shark displacement and triggering ecological cascades.

Does bathymetry drive coastal whale shark (Rhincodon typus) aggregations? [PDF]

PeerJ, 2018
Background The whale shark (Rhincodon typus) is known to aggregate in a number of coastal locations globally, however what causes these aggregations to form where they do is largely unknown.

Improving sightings-derived residency estimation for whale shark aggregations: A novel metric applied to a global data set

Frontiers in Marine Science, 2022
The world’s largest extant fish, the whale shark Rhincodon typus, is one of the most-studied species of sharks globally. The discovery of predictable aggregation sites where these animals gather seasonally or are sighted year-round – most of which are ...

Analysis of the temporal and spatial variability of whale shark (Rhincodon typus) aggregation in the South Ari Marine Protected Area, Maldives, Indian Ocean

The European Zoological Journal, 2021
Whale sharks are known to aggregate in coastal areas. In the South Ari Marine Protected Area (Maldives) a aggregation, mostly represented by young males with a high level of residency, has been described in the literature.

Prospects for whale shark conservation in Eastern Indonesia through bajo traditional ecological knowledge and community-based monitoring

Conservation & Society, 2012
The whale shark, Rhincodon typus, is a long-lived migratory species inhabiting tropical and warm-temperate waters worldwide. Seasonal aggregations of whale sharks in shallow coastal waters of many countries have led to the development of ecotourism ...

Fear at the top: killer whale predation drives white shark absence at South Africa’s largest aggregation site [PDF]

African Journal of Marine Science, 2022
Risk-induced fear effects exerted by top predators are pervasive in terrestrial and marine systems, with lasting impacts on ecosystem structure and function.

A Cocktail of Plankton and Organochlorines for Whale Shark in the Foraging Areas of Nosy Be (Madagascar)

Diversity, 2023
Seas and oceans are contaminated by persistent organic pollutants (POPs), which are released into the environment by human activities. The chemical-physical properties of POPs induce high persistence and toxicity in marine organisms from the lowest to ...

Draft sequencing and assembly of the genome of the world’s largest fish, the whale shark: Rhincodon typus Smith 1828 [PDF]

BMC Genomics, 2017
Background The whale shark (Rhincodon typus) has by far the largest body size of any elasmobranch (shark or ray) species. Therefore, it is also the largest extant species of the paraphyletic assemblage commonly referred to as fishes. As both a phenotypic

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 ...

Whale shark economics: a valuation of wildlife tourism in South Ari Atoll, Maldives [PDF]

PeerJ, 2014
Whale sharks attract large numbers of tourists, divers and snorkelers each year to South Ari Atoll in the Republic of Maldives. Yet without information regarding the use and economic extent of the attraction, it is difficult to prioritize conservation or
