Two dead whales have washed up on Unalaska's shores in the past week: an adult fin whale — which is the second largest mammal in the world — and a juvenile humpback.

It is thought to be either an aborted fetus or a very young calf. The calf is one of six belugas that have been found dead this year, five in the last month.

It is still not clear if the family was brought so close to people by hunger as most locals believe or, as one account suggests, out of fear of being followed by an aggressive large male.

The seven northern bottlenose dolphins were spotted stranded on a beach in Rossnowlagh, County Donegal, on the north west coast of Ireland, earlier today.

Between 2015 and 2020, two Unusual Mortality Events have been declared for wales along the western coast of British Colombia and the United States, indicating the possibility of a disturbance to the marine ecosystem.

This was a first expedition by volunteers and activists to rescue seals trapped in plastic rubbish on the island, a breeding ground in the Sea of Okhotsk, off Sakhalin.

The sea lions have posed a long-running conundrum for wildlife officials, pitting mammals protected under federal law against protected — and valuable — fish runs.

Officials have been receiving reports of Steller sea lions hauling out on beaches in poor condition, but have been unable to retrieve the animals for research — largely because they are in remote areas.

This orca born in 2018 is called Tl’uk, a Coast Salish word for “moon.” Tl’uk is a greyish moon color, without the typical black and white pattern.

"It's been sitting up on the beach just putting his head up towards the sky and not making a sound."

Southern resident killer whales made their first appearance in the Salish Sea on Canada Day after more than two months with only a brief sighting off the west coast of Vancouver Island.

First time we have ever seen a dead pup.

A beluga whale was spotted Friday off San Diego -- the farthest south the species has been documented on the West Coast, the National Oceanic and Atmospheric Administration confirmed.

The Seward facility began housing five seals found in the Cook Inlet area and another that was rescued in Juneau.

A public health advisory sent out Friday says anyone who has eaten uncooked walrus recently, and has experienced stomach pain, muscle pain, diarrhea, swollen eyelids, sweating and weakness, may be infected with trichinella, 'a parasite that causes worm disease.'

A video posted to social media shows the seal sunbathing on a floating dock in Laval, close to where the Mille Îles River joins the St. Lawrence River.

Female Stellar sea lion found dead on the beach, partially scavenged by eagles. There was no sign of any bullet holes. In addition, there wasn't any other evidence of what happened to the sea lion.

The early arrival of the dolphins can be attributed to rainfall from cyclone Nisarga that caused rainfall over the Chure range.
