New research shows how marine mammals ignore the rules of biology to thrive in the world's coldest waters
Two bottlenose dolphins (
Tursiops truncatus) cooperate in a button-pressing task requiring precise behavioural synchronization.

Dolphin pairs had to learn to push buttons at the same time to get a reward. So what happened when one dolphin figured that out, while the other still had to learn?

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.
Bottlenose dolphins, are very coastal and subsist on small fish connected to reefs and smaller bays.
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?
Leaping bottlenose dolphins.
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?
Dolphins contribute important knowledge about ocean health.
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.
Swimming in synchrony is a fundamental social behaviour for dolphins and is thought to reinforce their bonds.
A new study of captive dolphins has found that those engaging in synchronised swimming make more optimistic judgements about an unknown event.
No deep voices here.
Size doesn't always matter when it comes to the pitch of your voice, especially if you're an aquatic mammal.

Some dolphins live close to the shore, where they regularly encounter humans. This is affecting their numbers.
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.

The Great Barrier Reef is home to some 1,600 species of bony fish, 130 sharks and rays, and turtles, mammals and more. Most have had no population monitoring, meaning we don't know how well they are faring.
