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.
