Male deer are known to see other males as competition, especially during the autumn mating season. They will entangle their horn onto the other male horn, to try to take them out. @honeoyaji from Twitter took this photo and it’s amazing that the neck from the lost deer was torn and half skeletonized. 2ch comments: ・Wow, I couldn’t see the other deer from fist glance at this photo ・What’s this? Did it tear off the enemy’s neck? ・He’s just hallucinating with the feeling of guilt for the enemy he killed. ・↑Wow, he’s so guilty the illusion was embodied ・It was so entangled and couldn’t be removed, so was screwed off…
