Scientists are working to find the cause of death of a massive 50,000 pound whale that washed up on shore.

The IWDG says a minimum of 16 beaked whale deaths were recorded along the North West coast of Ireland from Galway to Donegal between 3 and 22 August, 2018.

A member of a species of critically endangered whale that is struggling with poor reproduction has been found dead off of Massachusetts.

A lone hiker in East Iceland found a wandering walrus, and managed to snap some fantastic photos.

Many of the dead seals that washed ashore in northern New England in the past few weeks tested positive for either avian influenza or phocine distemper virus, but it is still too soon to say if those viruses are the primary causes of the unusual die-off.

Nine whales have been stranded so far this year in East Iceland. Bottlenose whales and Curvier’s beaked whales are members of the family Ziphiidae and it’s often been said that they are more sensitive to noise pollution in the ocean.

Preliminary results suggest that avian flu and/or phocine distemper virus may be contributing to the elevated seal strandings in Maine, New Hampshire, and Massachusetts since June 1, 2018.

Marine mammal experts are testing tissue samples for a potential common cause of the surge in carcasses found on the state's beaches this year.

An unusually high number of northern bottlenose whales (Hyperoodon ampullatus) have been sighted in fjords in North and East Iceland.

A rare whale-dolphin hybrid species has been discovered off the coast of Hawaii, scientists say. The animal is the first-ever documented offspring of a rough-toothed dolphin and the rare melon-headed whale, a team from the Cascadia Research Collective concluded in a report released this week.

But an Icelandic whale-watching crew spotted the right whale named Mogul three times this week, leaving a research scientist wondering why the animal ventured so far.

The smelly carcass, identified as that of an adult male minke whale, is the second large marine animal to turn up on shore in southern Maine in the past week.

Polar bears have been rummaging through science camps at the top of Greenland's ice sheet far inland, where they were never expected, and Polar bears are coming into communities more often these days, says Kristin Laidre, a marine biologist at the University of Washington’s Polar Science Center, and an authority on polar bear populations in Greenland. “It’s happening all over the Arctic, and it’s something that’s only going to be an increasing problem as we continue to lose sea ice,” she says.

Residents of Chevak and Hooper Bay found two species of sea bird either dead or approachable near the mouth of the Kiuqliiviq and Aprun rivers near fish camps. Residents of Hooper Bay also found a dead sea mammal on the beach.

The population of endangered killer whales has hit a 30-year-low, numbering only 75 this year.

There’s only one historical record of a great white shark in the Bering Sea: fishermen caught one nearly 40 years ago. But scientists have reason to believe that in recent years there might be more of the predators around.

Rangers discovered the whale on Saturday, the cause of death is unknown.

The Marine Animal Response Society is keeping a close eye on the minke whale population in the Maritimes after at least 14 of them have been observed dead at sea or washed ashore since February.
