Bowhead whales come to Cumberland Sound in Nunavut to exfoliate

Wed, 22 Nov 2017 15:10:41 EST ~ Aerial drone footage of bowhead whales in Canada's Arctic has revealed that the large mammals molt and use rocks to rub off dead skin. Find out more...

Righty blue whales sometimes act like lefties, study finds

Mon, 20 Nov 2017 12:09:43 EST ~ To support their hulking bodies, blue whales use various acrobatic maneuvers to scoop up many individually tiny prey, filtering the water back out through massive baleen plates. In most cases, the whales roll to the right as they capture their prey, just as most people are right-handed. But, researchers now show that the whales shift directions and roll left when performing 360 barrel rolls in shallow water. Find out more...

Recovery of West Coast marine mammals boosts consumption of chinook salmon

Mon, 20 Nov 2017 08:54:19 EST ~ The researchers estimate that from 1975 to 2015, the yearly biomass of chinook salmon consumed by pinnipeds (sea lions and harbor seals) and killer whales increased from 6,100 to 15,200 metric tons, and from five to 31.5 million individual salmon. Find out more...

Shifting presence of North Atlantic right whales tracked with passive acoustics

Wed, 15 Nov 2017 10:48:37 EST ~ A new study confirms what marine mammal researchers have suspected for a while: right whales use nearly the entire eastern seaboard during the winter, and they move around a lot more than was previously thought. How long they spend in some areas of their range has also changed in recent years. Find out more...

Right whales, already an endangered species, may face a dim future

Mon, 30 Oct 2017 15:44:41 EDT ~ Researchers show that right whales, already an endangered species, may face a dim future. Find out more...

Weak social ties a killer for male whales

Tue, 24 Oct 2017 23:28:27 EDT ~ Male killer whales are more likely to die if they are not at the center of their social group, new research suggests. Find out more...

Whales and dolphins have rich 'human-like' cultures and societies

Mon, 16 Oct 2017 12:22:01 EDT ~ Whales and dolphins (cetaceans) live in tightly-knit social groups, have complex relationships, talk to each other and even have regional dialects -- much like human societies. A major new study has linked the complexity of Cetacean culture and behavior to the size of their brains. Find out more...

'Killer' toothaches likely cause misery for captive orca: Whales chew concrete and steel tank surfaces

Wed, 11 Oct 2017 18:05:50 EDT ~ An international research team has undertaken the first in-depth investigation of the teeth of captive orca (killer whales) and have found them a sorry state, which raises serious concerns for these majestic mammals' overall health and welfare. Find out more...

Scientists eavesdrop on little-known beaked whales to learn how deeply they dive

Wed, 11 Oct 2017 12:03:07 EDT ~ Scientists have reported the first dive depths for Gervais' and True's beaked whales, two of the least known beaked whale species known as mesoplodonts. The study is also the first to use a towed linear hydrophone array to document dive depths for beaked whales, and researchers say it's a promising method to obtain dive depths for other beaked whale species.

Humpback whale blow microbiome described

Tue, 10 Oct 2017 13:39:30 EDT ~ For the first time, scientists have identified an extensive conserved group of bacteria within healthy humpback whales' blow -- the moist breath that whales spray out of their blowholes when they exhale. Find out more...
