This past weekend a group of hunters on all-terrain vehicles found four dead bowhead whales lying on a beach about 60 kilometres north of the Nunavut community of Kugaaruk. Photos of the bowhead whales taken by Rene Kukkuvak, appear to have a torn tongues and rake-like gouges.

The Moray Firth dolphins have been moving out of their normal range in Scotland waters. A dolphin known as Yoda is the latest member to be spotted far from home. Another Moray Firth dolphin has been seen in the Irish Sea.

Khalaktyrsky Beach near Petropavlovsk is littered with hundreds of dead sea animals, from deep-sea Giant Pacific octopuses, to seals, sea urchins, stars, crabs and fish. Surfers were the first to raise alarm after problems with eyesight, fevers and throat aches.

Scientists worry for the pup's survival. Due to the pup’s albinism, it not only has bad eyesight, but could also be ostracized by the colony due to its unique characteristics.

“For the killer whales, I honestly don’t know if this is normal or not,” said Mandy Keogh, the Regional Marine Mammal Stranding Coordinator for NOAA Fisheries in Alaska. Dead killer whales simply aren’t seen that often.

The man, identified as 38-year-old Dutch citizen was attacked in his tent before dawn and died shortly afterwards of his injuries. Svalbard officials say there were seven people on the site at the time and they are being looked after by health services.

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.
