Researchers on an expedition 300 kilometers west of Vancouver Island stumbled upon a group of 25-30 endangered sei whales.

The whale had earlier been spotted stranded.

The community of Gambell fought a distemper outbreak among its dog population this spring and managed to squash the epidemic in its early onset. Distemper is a deadly disease that can afflict dogs and wildlife alike and also has been documented in the North Atlantic to jump from dogs to marine mammals like seals.

The beluga had a ruptured intestine probably related to parasites, which were found in the whale’s abdomen, lungs and kidneys, Burek said. The parasites likely led to an entanglement within a section of the intestines, leading it to rupture. “Very unusual,” Burek said. “I’ve never seen anything like that before.”

A long-deceased adult gray whale washed ashore near Klipsan Beach last week.

The 60 ft blue whale carcass drifted ashore near Walvis Bay, Namibia on Tuesday. Local authorities were alerted and are planning to move the body, which had several injuries.

The carcass of a 41-foot adult female gray whale landed at San Francisco’s Crissy Field on March 31. A second adult female was found April 3 at Moss Beach in San Mateo County. A third was found April 7 floating near the Berkeley Marina and the following day another at Muir Beach. A video of the fifth dead whale was posted on social media Friday.

Researchers in Canada find that population did not bother making the 6,000km roundtrip in 2018-2019

The carcasses of four gray whales have been found around the San Francisco Bay Area in eight days -- an alarming string of deaths that constitutes an unusual mortality event, defined by the National Oceanic and Atmospheric Administration (NOAA) as a significant die-off of a marine species.

A gray whale carcass washed ashore at Crissy Field on Wednesday morning. Veterinarians and biologists from the center and from the California Academy of Sciences plan to perform a necropsy in coming days on the island to determine the cause of death.

More than 27 people in Inukjuak may have been exposed to botulism after consuming contaminated walrus meat served at two recent feasts. The Nunavik regional health board made the announcement on its Facebook page on Saturday.

Marine biologist and director of Dingle’s OceanWorld Aquarium, Kevin Flannery, told the Irish Times it is “very unusual” for a walrus to be spotted in this part of the world, although there have been potential sightings from surfers and fishermen in Ireland in the past.

The racing predator was seen 60km south of Batagai, north-east from republic’s capital Yakutsk.

The Coast Guard reported the dead 47-foot female humpback to NOAA on Sunday evening. It had washed ashore on the south end of Kruzof Island. The whale looked healthy and its belly was full of fish — most likely herring. But they did find some evidence of blunt trauma.

A dead humpback whale has washed ashore on North Carolina’s Outer Banks. The Charlotte Observer reported Thursday that the 18-foot whale was found on Pea Island about half-mile north of Rodanthe.

A harp seal pup sits on a snow-covered beach near the town of Blanc-Sablon, Québec, in early March. Normally harp seals give birth and raise their pups on sea ice in the Gulf of St. Lawrence, but this year’s ice coverage is at an all-time low, throwing pups’ survival into jeopardy.

As sea ice off Alaska continues its long-term vanishing trend, two seal species that depend on ice may be showing the effects in their bodies. Ribbon seals, distinctive for their black-and-white striped patterns on their fur, and spotted seals, known for their speckled coats, became thinner over time.

A roughly 25-foot gray whale washed ashore and died Wednesday on Dockweiler State Beach south of Marina Del Rey.

A walk in the woods behind Glanleam beach on Valentia Island for local man Alan Houlihan and his daughther, Muireann (Mimi) (5) on Sunday morning took a rather unusual twist when the pair spotted a walrus out on the rocks, just off the beach.

Cold stress accounts for at least 39 of the deaths, or about 10%. For 277 others, almost 70%, the cause is unknown. Biologist suspect the sea cows are starving to death as the marine mammal’s main diet of seagrass wilts under ongoing years-long ecological collapse, driven by excess algae.
