On New South Wales’ southern coast, First Nations groups and European whalers hunted alongside orcas. But what happened to this unusual group?
Unusual human-wildlife interactions raise questions about managing the risks. What’s driving these wacky whale antics? How and when should we intervene?
Orcas appear to be imitating the behaviour of one in particular by damaging sailboat rudders.
By analyzing small samples of killer whale fat, scientists can learn about the diets of different killer whale populations. This has implications for our understanding of changing ecosystems.
Women live longer than men, yet they cease reproductive life earlier than men because of the menopause. Why this apparent contradiction?

A pair of killer whales are hunting and preying on South Africa's great white sharks, forcing the sharks to flee.
A terrifying sight in ancient waters, the megalodon shark was once the most feared creature in the sea.
Whale species at higher risk of predation from killer whales are more adversely affected by the sound of sonar.
Killer whales among the animals at risk from a ‘second wave’ of pollutants, as coasts erode and sea levels rise.
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.
Scientists had been uncertain about why killer whales are dying in the northeastern Pacific Ocean. A new study takes an in-depth look and provides the tools to help prevent additional deaths in the future.
Regulations have lowered mercury emissions globally, but the risks to ocean ecosystems and human health may be getting worse.
