Dolphins

Gripping onto the edge of an iceberg in East Greenland, a polar bear looks out across the sea ice and sniffs the air. “The scene reflects a landscape that never stays still, where ice fractures, drifts and reforms around it,” photographer Rhiannon Lawler of the United Kingdom writes in a caption. Lawler captured the photo with a drone, keeping a safe distance from the animal.

Orcas and dolphins might hang out together off the coast of British Columbia to hunt for food as a team, new research suggests.

Watch These Orcas Follow Dolphins to Snag a Salmon Feast. It Might Be the First Evidence of These Species Working Together

Off the coast of British Columbia, killer whales are tailing dolphins, and both seem to be rewarded with fishy meals. But not everyone is convinced it’s teamwork—and the behavior may hint at other ocean stressors

The new world of information supplied by drones hovering above is allowing researchers to more easily measure whale size, body condition and health; to identify individual animals from features on their bodies; and more.

From Collecting Whale Snot to Capturing Surprising Behaviors, Aerial Drones Are Giving Scientists a New View of Sea Life

The robots can hover over marine mammals and gather all sorts of information in a way that’s less invasive to the animals than researchers trying to approach them by boat or plane

The epigenetic clock is emerging as a wildlife conservation tool.

This ‘Clock’ Could Warn of Hidden Stresses to Animals, Offering a Long-Sought Signal That a Population Is Nearing Collapse

The epigenetic clock measures biological age and could help scientists assess the health of polar bears, dolphins, baboons and other threatened creatures “while recovery is still possible”

Many different types of animals, from birds to orcas, are affected by human noise.

Five Dramatic Ways Animals Respond to Human Noise, From Mimicking Car Alarms While Wooing Mates to Calling Higher Over the Din of Traffic

As human-caused sound gets louder around the world, some animals change their behavior and many creatures suffer health issues

A bottlenose dolphin is seen "bow riding," or swimming just in front of a humpback whale, potentially getting a boost from the wave created by the larger mammal.

Whales and Dolphins Interact More Often Than Scientists Thought, Engaging in Mutual Play, Study Suggests

Researchers analyzed nearly 200 videos and photographs documenting interactions between the various kinds of cetaceans

Killer Whales Hunt Fish in Highly Coordinated Pairs and Perfect Their Movements With Practice, Drone Videos Reveal

Footage taken off the coast of Norway reveals that orcas team up to maximize their prey, according to a new study

Orcas are highly social creatures that often share prey with each other. Now, new research suggests they're extending this behavior to humans.

Orcas Appear to Be Sharing Their Prey With Humans—but What Does It Mean?

Researchers documented 34 instances of purported prey-sharing behavior, which suggests orcas may be altruistic and capable of recognizing sentience in another species

These Killer Whales Make Tools From Kelp to Massage Each Other in a Newly Discovered Grooming Behavior

Dubbed “allokelping,” it might be a unique cultural phenomenon that’s as endangered as the orca population itself
