Olive baboons show their ferocious teeth as they playfight

Olive baboons are large, solid primates that can reach 70cm (28 inches) in height and an impressive weight of 50kg (110lbs). They are one of the largest monkey species and one of the most widely spread. Not surprisingly, their teeth are also among the largest of the monkeys. These two olive baboons engage in a friendly playfight in the sunshine, possibly vying for dominance in the troop. As they do so, they display a fearsome set of teeth that are obviously capable of causing severe damage, if the baboon chooses. They have elongated, dog-like muzzles and powerful jaws.
The social structure of these baboons is complex, and fascinating. The troops consist of 15-150 individuals with more females than males. There are dominant males within the troop, and also higher ranking females. The higher ranking females are more likely to reproduce, but the whole process of reproduction involves surprising behaviours.
A female who is pregnant is highly likely to be harassed by males in an apparent attempt to cause miscarriage of offspring that do not belong to the male perpetrator. This creates an opportunity for the male to mate with that female earlier, as well as a higher likelihood of passing on his genes. Following delivery of an infant, males in the troop will protect her and the infant, especially those who are allowed to mate with her. This means that the male is better to focus his attention on pregnant females who do not have the protection of their male allies.
Male olive baboons are highly aggressive with each other in their attempts to mate with females. Younger males are constantly trying to increase their rank in an effort to gain breeding rights. Baboons will often form alliances and coalitions within the troop,
This display could be a matter of complex social interaction for many reasons, but it is clear to see that a fully grown baboon is a force to be reckoned with for any animal.
