Just about every creature on Earth needs to grab some Zs from time to time. Imagine trying to doze while dodging great whites and killer whales.
Using urine and signature whistles from other dolphins, a team of scientists has shown that dolphins use signature whistles like names and hold mental representations of other dolphins in their minds.
Many of Africa’s large aquatic animals, such as dolphins, manatees and turtles, are being killed for meat.
North American red squirrels produce a range of sounds, but their distinctive rattle call may have more to do with identifying themselves than warning off other squirrels.
Whale species at higher risk of predation from killer whales are more adversely affected by the sound of sonar.
There are some important issues to consider to best help marine species such as Atlantic puffins, bottlenose dolphins and orcas.
Some animals, such as California sea lions, have small brains relative to their body size, but are still impressively intelligent, showing brain evolution is even more complex than it appears.
The cetacean brain has a specialised thermogenic system that helps the animal’s brain to produce enough heat to maintain a functional brain temperature.
It’s time to listen to warnings from the people of the Pacific.
More than 450 long-finned pilot whales are stranded in Tasmania. Saving them is a race against time.
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.
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.
New research shows how marine mammals ignore the rules of biology to thrive in the world’s coldest waters
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.
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?
