Nearly a century after we almost hunted them to extinction, fewer than 360 right whales remain.

About 44 per cent of migratory species worldwide are declining in population, the report found. More than a fifth of the nearly 1,200 species monitored by the UN are threatened with extinction.

According to a new report, plastic bag bans can eliminate nearly 300 single-use plastic bags per person per year.

Marine scientist Kieran Cox calls it "probably the most pervasive, unregulated pollutant in Canada and globally."

The decline of one of the rarest whales in the world appears to be slowing, but scientists warn the giant mammals still face existential threats from warming oceans, ship collisions and entanglement in fishing gear.

From great white sharks around Quebec's Îles-de-la-Madeleine to lobsters conquering new territory, oceanographers say the warming of the Gulf of St. Lawrence is having an impact on the creatures that live in its unique ecosystem.

Five years ago today, the orca mother J35 — also known as Tahlequah — gave birth to a calf who died shortly thereafter. In response, Tahlequah proceeded to carry her daughter’s body across the Salish Sea for 17 days, a 1600 kilometre journey of mourning that went viral at the time.

Marine scientists and conservationists are calling on officials to pause Newfoundland and Labrador's commercial capelin fishery.

As wildfires from coast to coast scorch large swaths of forest, sometimes changing it irreversibly, experts have zeroed in on an often overlooked casualty of the blazes: wildlife.

Whales seem to find food by sniffing for a chemical cue. Scientists are hoping to turn this into an early warning system to help save the imperilled species.

As climate change causes more marine heat waves, finding space for both is getting even more difficult.

Understanding why some animals are more susceptible to the disease could lead to improved screening for humans.

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

Praise poured in from Canadian environmental groups on Sunday, March 5, 2023, for a newly signed treaty that will help protect biodiversity in the high seas, where conservation efforts across vast stretches of the planet have historically been hampered by a confusing patchwork of laws.

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.
