Whale breaches and tail slaps look great from a distance. But they can pose a threat if you want to get up close and swim with these giants of the ocean.
How we worked out when whales first evolved asymmetrical skulls.
Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.
Some species, including blue whales, spend little time at the surface. So despite their overwhelming size, they can be hard to find and tough to study.
Icelandic whalers have killed more than 1,700 whales since a global ban was adopted in 1986 – up to 2019, when no hunts took place. Is Iceland quietly getting out of the business?

The Great Pacific Garbage Patch, a floating accumulation of rubbish the size of a continent, has whales and dolphins in its heart.
Do animals have their own culture? A researcher studying the culture of whales argues that they do. She says understanding that may be one way to save them from extinction.
These small shrimp-like creatures are more than just whale food.
Dead whales usually sink, so most evidence of 'ship strikes' quickly disappears beneath the waves.
Scientists have used drones and 3D modelling to work out the weight of Earth's largest mammals without killing them.
The Trump administration is changing implementation of the Endangered Species Act in ways that conservationists say would reduce protection for some of America's most threatened wildlife.
As the field of animal law continues growing, so does public awareness of the problems with inconsistent ways that Canadian law protects some animals, while leaving others behind.
