A wildlife photographer in Alaska caught two massive male grizzly bears on video in what he said was "the longest, most intense bear interaction I have ever witnessed."

On May 8, Brad Josephs was visiting Lake Clark National Park and Preserve in southern Alaska when he caught the two grizzly bears (Ursus arctos horribilis) going head-to-head in a show of dominance during mating season, according to Outside magazine. The fight wasn't between equals, either; one male was larger and older while the other was smaller and younger, according to PetaPixel
