Two groups of Pacific walrus have been found dead along the Chukchi Sea northwest of Alaska. One incident is the subject of a criminal investigation. The other has been blamed on natural causes.
Walrus carcasses were found last week on a northwest Alaska beach, but the U.S. Fish and Wildlife Service says the deaths appear to be natural.
The U.S. Fish and Wildlife Service said Friday it is investigating the deaths of 25 Pacific walrus found on an isolated northwest Alaska beach.
The U.S. Fish and Wildlife Service has declined for now to create artificial floating platforms for Pacific walrus that come ashore in Alaska because they lack summer sea ice.
