'Alpha'

Chacma baboons are sexually dimorphic with females weighing as little as 50% of that of males. Males can reach a height of 120cm and weigh as much as 40kg. Males also brandish huge canines measuring up to 5cm, longer than a lions. The dominant 'Alpha' male will generally be the largest and has the task of protecting the group, in particular the females and youngsters. One moment a tender father, the next a formidable fighter as he protects his position from other males in the troop.
This is the closest I have ever been to an Alpha male baboon (around 3 meters), this guy normally remains on the outskirts of the group keeping a watchful eye on me when taking photos, so it was quite an exhilarating experience!
