Northern sea otters, once hunted to the brink of extinction along Alaska's Panhandle, have made a spectacular comeback.

The first right whale of the season has been spotted in Canadian waters after an unprecedented winter in which not a single calf was spotted.

Sea ice has shrunk, but scientists are seeing signs that Alaska's bowhead whales are flourishing.

The Finnish Coast Guard came to the rescue of a whale caught in a fish trap on Saturday in the narrow region of the Gulf of Bothnia known as Kvarken.

At the time of the encounter, Einar had been line fishing for a while. He and his boatmate had just been talking about how many whales were around.

Two hundred walruses surprised residents on an Alaskan peninsula after arriving en masse on a beach.

The ice conditions are similar to last year (with) lots of young ice and close leads," said Captain Frederick Brower. "We all went out and broke trail to the edge, but a high west wind came along and added about three-quarters to 1 mile of ice and (we) had to break trail through that and began whaling from the new edge ... . The conditions were not favorable but we made due with what we had and continued on with our whaling season."

Residents saw a few hundred walrus hauled out at the beginning of April. By the end of April, they reported seeing about a thousand. On a recent flight over the shoreline, an ADF&G biologist saw only 100.

Unalaskans are used to spotting marine mammals around the island. But lately, they're not just seeing whales or otters. They're seeing ringed seals — an Arctic species that typically lives far north of the ice-free Aleutian Islands.

Biologists are investigating a surprising connection between two animals that aren’t exactly well loved in parts of Southeast. Gustavus locals suspect wolves are picking off deer at a popular hunting spot on an island near the mainland.

Pregnancy rates in the southern oceans are high, according to a study that showed that Humpbacks are rebounding.

Underwater recordings confirm that a new killer whale population is poking its head into British Columbia.

The walrus count at this location was approximately 500-1000, and looks like they are here to stay well at least for this season of time before they return to the north.

The herds are increasingly moving around in Bristol Bay, perhaps seeking new feeding grounds, a biologist said.

We discovered numerous large marine bivalve shells (and two chiton shells) that had been cracked recently by sea otters. Ocean View Beach is around the southern extent of Vancouver Island and back again north in the Strait of Georgia. The present observation is evidence of sea otters traveling into the Strait of Georgia.

Walrus in Bristol Bay and Port Heiden are not uncommon in summer. The fact they are present in April is unusual and residents believe factors such as the lack of sea ice, lack of food and warming ocean temperatures may be the reason.
