Looks like the set for the next Mission Impossible, but for Nubian Ibexes, the high-altitude rocky terrains are home. The vulnerable ibex species is known for many things–large semi-circular horns, the ability to scale mountains with ease and the territorial fights that males engage in during the rutting season. Displays of dominance begin with showing off their impressive horns. If that doesn't do the trick, it's time to escalate by pushing and shoving the opponent and literally locking horns with them. Ibexes also stand on their hind legs as they get ready to strike.
