Gustavus Wolves and Sea Otters

While most wolves prefer moose, deers, and mountain goats, the Gustavus pack in northern Southeast Alaska has developed a taste for sea otters, most likely due to a a rapid growth in the population in the Glacier Bay National Park.

It’s not certain how the wolves are killing the sea otters. Otters are known to come ashore during inclement weather, and it’s possible that the wolves are hunting them them then. Research also suggests that the sea otter population in Glacier Bay has reached “carrying capacity” (the point at which a habitat can no longer support the number of animals living there without damage to the habitat or animals). If this is the case, wolves could be scavenging dead animals that wash up onshore or going after weakened otters.
