The shocking footage shows the two aggressive bears in the middle of a vicious fight, which ended up with both walking out alive.
The two brown bears are clearly clawing each other and the smaller one eventually lost.
Daniel Bunker, 42, from Homer, Alaska, captured the moment at coast of Cook Inlet near Lake Clark National Park, on the 27th of May.
Daniel said: “It was quite a roller coaster of emotions watching this bear fight unfold.
“At first I was hoping the bears interact but then I was cringing as they violently bit and clawed each other.
“It was the longest and fiercest bear fight I have ever seen. The smaller bear eventually lost and was pinned in the mud by the bigger bear, but both walked away alive.
“This area has one of the highest concentrations of brown bears in the world.
“Early in the summer, similar sized bears may face off or fight to see who is more dominant.
“These two male bears walked near each other and faced off before deciding who was boss with a gnarly, all-out fight.”
