(Corvallis, OR) -- New research from Oregon State University shows wolves on a remote Alaskan island ate nearly the entire deer population and then turned to sea otters. OSU researchers believe it's the first case of sea otters becoming the primary food source for a land-based predator. When the deer population dwindled to almost nothing, the researchers thought the wolves would leave or die from starvation. Instead, they started eating sea otters while they were in shallow water or on rocks at low tide. The research is now being expanded to Katmai National Park & Preserve, where the same thing appears to be happening.
