"Going forward, the priority is to continue using these methods for long-term surveillance." Scientists make troubling ...

Scientists have discovered a new, much less invasive method for testing whales for pathogens. In the past, scientists needed to take biopsies from whales, which left a small wound, to test for ...

A new study found that neurotoxins in whales pose risks to Native whale-hunting communities. Arctic whales are ingesting higher levels of toxic algae as warming waters create more suitable conditions ...

In a warming Arctic, noise from growing shipping traffic is interfering with the ability of narwhals to hunt and communicate.

For most of their evolutionary history, narwhals have relied more on sound than sight to survive in the Arctic’s dark icy ...

Beluga whales can disappear beneath Arctic sea ice for long stretches, which makes them far tougher to follow than many other whale species. That is why researchers have increasingly turned to ...

With the rapid melting of Arctic ice, the waters have opened up to more human traffic, which is disturbing the underwater ...

In the icy waters of Alaska's Bristol Bay, a new study reveals how a small population of beluga whales (Delphinapterus leucas) survive the long haul through a surprising strategy: they mate with ...

Beluga whales indulge in wife swapping to enhance their long term survival chances, reveals new research. Ground-breaking DNA analysis shows both males and females of the species that live in the cold ...

For around three decades, researchers have been extracting samples of whales and prey at Gulf of St. Lawrence and found ...

Among marine mammals, beluga whales ( Delphinapterus leucas) are particularly difficult to study in their icy habitat. To better understand and protect this endangered species, scientists must piece ...
