A family of killer whales was spotted near downtown Vancouver in a rare sighting likely linked to hunting for seals.

A headless harbor seal was discovered at Letnikof Cove, raising questions as scientists from NOAA investigate the cause of death and post-mortem scavenging.

A 47-foot fin whale washed ashore near Anchorage's Westchester Lagoon. Biologists believe it is a young female and are investigating the cause of its beaching.

The Orca Conservancy said the sightings made history. Some whale watchers hope it will again raise awareness of the need to protect them.

Researchers in Washington reported observing orcas in Puget Sound balancing salmon on their heads, a behavior not seen in decades.

A new plant species is establishing itself in the area and impacting native beach greens.

No obvious cause of death for this adult and juvenile otter.

Orcas are starting to show new feeding behaviors around large trawler nets. They’re trying to steal fish caught in nets that are typically being hauled back. Scientists aren’t sure why orcas are doing this, but it’s dangerous for them because it increases their chances of getting caught in the net and dying.The problem is so bad that some fishermen have decided to skip fishing for black cod this year.

RÚV received a video this week that shows a whale just off the beach at Reynisfjara; the second time in about a week. Guðjón Már Sigurðsson, marine biologist and cetacean expert at the Icelandic Marine Research Institute, says the whale swims shallow in a search for food.

A worker with a logistics company that operates the North Warning System in Nunavut has died after being attacked by two polar bears on Thursday. 

“Last year we got several reports from tourists and scientists that they saw around six walruses dead here on the west side of Svalbard. Unfortunately, we couldn’t sample them as the dead walruses drifted away by the time we got to the place. But it’s not normal to get so many reported dead walruses in such a small area," said Christian Lydersen, senior scientist at the Norwegian Polar Institute. Now samples (collected by a Station Manager in July 2023) have tested positive for highly pathogenic avian influenza.

A polar bear was shot in Ittoqqortoormiit after being spotted wandering the streets, marking the second such incident in the town within a week.

An extremely rare Spade-toothed Beaked Whale Mesoplodon traversii washed ashore in Otago, providing the first chance to dissect and study such a specimen, with DNA analysis underway to confirm its species.

At least 65 long-finned pilot whales have died after being stranded on an island off the north coast of Scotland, a rescue charity said on Thursday, in one of the largest mass strandings in Britain in recent times.

Two harbor seal pups, one from Naknek and another from Wrangell, were recently rescued and are receiving care at the Alaska SeaLife Center due to malnourishment and other health issues.

A humpback whale named Stanislav was successfully freed from a fishing net in a first-of-its-kind rescue operation in Russia's Barents Sea.

A second seal pup has been rescued on Kenai Beach, marking the fourth such case for the Alaska SeaLife Center's Wildlife Response Program.

Observers in Port Heiden, Alaska report significantly reduced sea gull populations and fewer gull eggs for subsistence, coinciding with decreased seal numbers and increased fox populations.

While the population increased, the assessment did find that narwhals are sensitive to sound from boats and move away from boat traffic, Mike Hammill, the co-chair of COSEWIC’s marine mammals subcommittee, told Nunatsiaq News. Previously the species was listed as being of “special concern.”

Before she knew what was happening, a large female killer whale lifted Bloom’s paddleboard up out of the water. “And at that moment it was like terror,” Bloom said.
