A researcher says her team couldn't believe the distance travelled.

Mexico has spent US$17 million to remove over a half-million tons of sargassum seaweed from its Caribbean beaches, and the problem doesn't seem likely to end any time soon.

A satellite-tracked Arctic fox stunned researchers by making a 3,500-kilometer trek across Arctic sea ice and glacier to travel from the Norwegian archipelago of Svalbard to Canada’s Ellesmere Island in about two and a half months. “We first did not believe it was true,” rone of the researchers, Eva Fuglei, said about the amazing run

The glowing algae is suffocating sea life.

Two summers ago, federal scientists discovered something shocking: The Northern Bering Sea was teeming with cod and pollock. Those two commercially valuable species had never been found in such large huge numbers that far north.

'There's nothing good about them.' They carry disease and cause billions in damage

Scientists have identified a spike in ‘vagrant’ species of fish including damselfish, wrasse and triggerfish

The survey started in 1971 as a review of commercially important fish like cod and halibut, but has grown into an annual scientific assessment of all sea life hauled up from the deep.

A new study has documented unexpected consequences following the decline of great white sharks from an area off South Africa. The study found that the disappearance of great whites has led to the emergence of sevengill sharks, a top predator from a different habitat. A living fossil, sevengill sharks closely resemble relatives from the Jurassic period, unique for having seven gills instead of the typical five in most other sharks.

Climate change has opened region up for more of the year

Thousands of female penguins are being stranded along the coast of South America because of water pollution and fishing, research shows. A new study of Megellanic penguins, which breed in Patagonia in southern Argentina, explains for the first time why so many become stuck on beaches hundreds of miles further north.  Researchers found the man-made threats encountered as the

A 2008 report by the Canadian Food Inspection Agency said there were at least 486 invasive alien plant species alone in Canada.

The catch is shifting northward as water temperatures rise, forcing crews to retool their boats and rework their businesses. Pollock is retreating from Alaska while black sea bass throng around Rhode Island.

In 2016 and 2017 commercial fishers near Cambridge Bay in Nunavut were surprised when they pulled in sockeye salmon — because they were expecting to see only Arctic char. While these are just two fish, found far from their usual home waters, the two salmon are likely an indication that Pacific salmon will continue to

Polar bears, black bears, and grizzlies have been found together for the first time during a University of Saskatchewan research project in northern Manitoba.

This cute little guy makes you trip so hard you'll want to die, and could soon start popping up on the Gold Coast.

Crayfish were first observed on Kodiak around 2015. Now, a local tribal organization is studying their movement, distribution and diet.

Scientist warns of "seagrass crisis" in Caribbeans MEXICO CITY (Rahnuma): Massive quantities of Sargassum seaweed are invading Caribbean beaches mostly thanks to global warming and countries should work closely with scientists for a sustainable solution, said a researcher at a leading Mexican university on

A team of biologists is surveying a lake on Kodiak Island for crawfish, an invasive species in Alaska that has been observed in higher frequency over past several years.
