A wolf and a wolverine were caught on camera fighting over dinner inside Denali National Park and Preserve, Alaska, in February. The park service released the video on Wednesday, June 13, after researchers retrieved it from a wolf kill site.The video contains three segments, one showing the wolverine feeding on a moose carcass, then a wolf appearing and attacking the wolverine and, finally, the wolf feeding on the moose carcass after having chased off the wolverine.Motion-triggered cameras, along with radio collars, flight surveys and field observations, are used by researchers to understand the activities of wolves inside the park. The wolf in the video has a radio collar around her neck and was identified as a breeding female of the Riley Creek pack. Credit: National Park Service via Storyful
