This study provides the first evidence that penguins emit sounds underwater when they hunt.
The Great Pacific Garbage Patch, a floating accumulation of rubbish the size of a continent, has whales and dolphins in its heart.
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.

Researchers have discovered male bottlenose dolphins can retain individual vocal labels – or “names” – to help them recognise each other in their social network, much like humans.
A new report will supply some information needed for science based conservation measures in the Red Sea.
Researchers have found evidence of the same brain pathologies in dolphins that are present in the brains of humans who died with Alzheimer's. What might this suggest about Alzheimer's in humans?
The dolphin population in parts of Western Australia more than halved one year, just as an El Niño event hit over in the Pacific. So what's the connection?
Marine mammals are often referred to as sentinels of the ocean and research on whales and dolphins in particular contributes important knowledge about the health of our seas.
It's not easy to tackle a live octopus - so many arms, all those suckers! But some bottlenose dolphins have found a way to defuse and eat these eight-armed sea creatures.
A new study of captive dolphins has found that those engaging in synchronised swimming make more optimistic judgements about an unknown event.
Size doesn't always matter when it comes to the pitch of your voice, especially if you're an aquatic mammal.
Dolphin-watching tourism has pros and cons — so what should you think about next time you head out?
The most recent episode of the BBC's Planet Earth II has got people asking some hard questions about the world's most mysterious big cats.
Understanding this will boost conservation efforts.
Globally, a quarter of whale and dolphin species are endangered. Though South African dolphin populations are generally in good heath, the humpback dolphin is cause for concern.
Indian Ocean humpback dolphins, which live close to the shore, need protection. The total population is estimated to be just 10,000, with fewer than 1,000 of them off the coast of South Africa.
It didn't turn out well for the whale who went to Westminster, but others have made a happy home in British waters.
