killer whales

A family of killer whales has made a rare trip into waters off downtown Vancouver for what an expert says was likely a "grocery shopping" hunt for harbour seals.

A pod of killer whales has been spotted far offshore from the remote Vancouver Island inlet where an orphaned orca has been spending time since escaping a lagoon last month, but a member of her rescue team is downplaying the prospect of an imminent family reunion.

A new integrated network of hydrophones along the B.C. coast will allow the public and researchers to listen underwater to the magic of whale sounds and how they can be used to protect marine mammals into the future.

Researchers have solved the puzzle of how whales generate enough airflow 1,000 metres underwater, where pressure is 100 times that at the surface.

Researchers say British Columbia's southern resident killer whales are not only threatened by the decline of the overall salmon population but also the reduction in high-quality fatty salmon, the whales' preferred meal.

After 100 years of absence, large numbers of Pacific white-sided dolphins are back in the northern part of British Columbia's Salish Sea.

Outer coast killer whales, a little-known type of orca, have a vocal dialect and culture distinct from their West Coast cousins in B.C. and specialize in hunting big game, such as gray whale calves, massive elephant seals, and sea lions in California ocean waters.

Endangered southern resident killer whales would have a much better chance of survival if chinook were in their hunting grounds during winter off the coast of British Columbia, a new study says.

Known as “killer whales” for their ability to prey on larger whales, orcas in the Pacific Northwest have suffered from fatal encounters with ships and other vessels, malnutrition, disease, and accidental stranding due to sudden shifts in tides, according to a new study.

Transport Canada confirms it has issued 159 written warnings and logged 51 verbal warnings as of this month, and that those represented the entirety of the enforcement actions it took so far this year, pending some cases still “under review.”

After three years of searching, a U.S.-based conservation group has selected two prospective sites in rural Nova Scotia for a kind of ocean retirement home for beluga whales raised in captivity.

Scientists attending a national gathering of Arctic researchers are outlining a widening range of climate change risks for so-called "sentinel" species, such as ringed seals and beluga whales, which have sustained Inuit for millennia.

For many, declining southern resident killer whales represent an age of human-caused climate change and extinction. For Coast Salish communities, it’s personal.

A judge has dismissed the British Columbia government's request to declare unconstitutional an Alberta law that could restrict the flow of refined oil products to B.C.
