The cetacean brain has a specialised thermogenic system that helps the animal’s brain to produce enough heat to maintain a functional brain temperature.
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.
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.
Hector’s dolphins (Cephalorhynchus hectori) are found only in New Zealand.

The endangered Hector’s dolphins are found only in coastal seas in New Zealand, but conservation experts describe New Zealand’s proposed protection plan for the marine mammals as misleading.
New research shows dolphins have a large clitoris that is similar to the human organ.

It was not until the late 1990s that the anatomy of the human clitoris was accurately described by Australia’s first female urologist. And now research in animals is starting to catch up.
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?
Three allied male dolphins in Shark Bay, Western Australia.

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.

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?
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.
