It’s usually good news when a once-scarce species starts to recover – unless it starts getting in humans’ way. An ecologist explains how science can help predict unwelcome encounters.
No country has a higher diversity of sharks than Australia. That means we have a special responsibility to protect them.
The ‘SharkSmart’ approach, adopted by the Queensland government, aims to educate people to take responsibility for reducing shark bite risk by changing their own behaviour. But can humans change?
The death of 57-year-old Paul Millachip at Fremantle’s Port Beach is a reminder that shark bites, though rare, can be tragic. New research aims to reduce the risk by understanding sharks’ vision.
Nearly all species of sharks and rays are captured in fishing operations. But research shows that fishing quotas and closing some areas to fishing can help rebuild threatened populations.
Sharks have been around for more than 400 million years — but not all sharks are equally resilient to changes around them. Why do some groups thrive, while others dwindle?
Which species are becoming endangered and which are recovering, according to the IUCN World Conservation Congress?
These giant predators are helping solve the mystery of Earth’s cooling shift some 50 million years ago.
As part of the nation’s massive wartime mobilization effort, millions of Americans, for the first time, traveled abroad – where many had their first encounters with the marine predators.
From working on Jaws to putting herself in danger, Valerie Taylor vowed to change public attitudes to sharks. A new film dives deeply into her underwater life.
Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.
Scientists have long believed that sharks were the first vertebrates to evolve teeth. Our new study reveals a more complex history.
Tackling bycatch in large-scale fishing can make our seafood habit more sustainable
By measuring how and when elephant seals sleep, researchers were able to figure out how elephant seals change their risk-taking behavior as they gain weight.
As more and more plastic trash permeates the oceans, fragments are making their way into fish and shellfish – and potentially into humans.
A high seas treaty could help rebuild populations – but time is running out.
New fossil detective work sheds light on the life of megalodon, the biggest predatory shark ever discovered.
Parthenogenesis, a form of reproduction in which an egg develops into an embryo without being fertilized by sperm, might be more common than you realized.
You’re more likely to drown at a beach than be killed by a shark. But there are things people can do to reduce the already low risk even further.
