In just a few short years, the Northern California waters stretching from Sonoma to Southern Humboldt have undergone a dramatic transformation, with stretches stripped bare of their once varied marine life in a phenomenon known as "urchin barren."
There are many types of crabs that are green in colour, but only the European green crab has five spines on the outside of each eye. The aggressive invasive species was discovered in Skidegate Inlet; and now working group formed to decide next steps.
Scientists said the critically-endangered species had previously only been found in rivers and know pearl mussels have been discovered in the Scotland Lochs.
Thousands of lobsters, clams, quahogs and crabs have washed up on the shore at Robinson's Island, a consequence of no sea ice and big waves.
Victoria's biggest-ever reef restoration project is underway, in attempt to restore the once abundant populations of native oysters in Port Philip Bay.
Biologist Jackie Hilderling says four years of decline in B.C.'s sea star population is due to climate change warming local waters and making the animals susceptible to sea star-associated densovirus.
The colourful Portuguese man-of-war is more commonly seen in warmer waters. Their painful stings can be fatal to some.
For years, researchers thought an infectious pathogen was behind sea star wasting disease. A new study found that multiple species of bacteria deplete oxygen from the water effectively suffocating sea stars. These microbes thrive when there are high levels of organic matter in warm water and create the low oxygen conditions.
I've asked quite a few of the elders here if they had ever seen and none of them said they had ever seen it, said Skidegate Chief Councillor Bill Yovanovich, who took the photos Saturday on Lina Island. They show small bits of white shells arranged into what appears to be an intentional grid pattern that stretches at least a hundred metres along the beach.
The threshold for closure is set at 80 parts per million, but concentration in those areas were found to be as high as 1,300 parts per million.The warning applies to oysters, clams, scallops, mussels and geoduck.
Volunteers at the Whittier Slug-Out learned about Alaska’s invasive species and helped mitigate European black slugs near a popular cove on Prince William Sound.
Pyrosomes were first seen on the Oregon coast in 2014 and every year since. Recently they have been reported in Washington, BC and Alaska. These weird organisms that resemble large pink thimbles, could signal really big changes in the marine ecosystem.
What has eight hairy legs, one eye, no mouth and haunts the frigid waters below the frozen ocean? A speck of a creature you'd never know exists in Canada's Arctic, were it not for one researcher's accidental discovery off the shores of Cambridge Bay, Nunavut.
A big emphasis in the last few years has been updating and adding to the list of species known to occur in the Yukon. This past year, a whopping 1,973 species of plants, insects and animals have been added.
The so-called 'warm blob' of water in the North Pacific has brought unusual plankton, which lack the nutrients wild salmon and other marine animals count on.
Sea star wasting disease, a type of densovirus, reduced the count of sea stars in Kachemak Bay from 180 last spring to a measly five this year.
