Which is ferocious Baboons or Orangutans?

Baboons are generally more aggressive than orang-utans. Baboons live in large groups, in which males fight for dominance and access to females. They will also hunt small animals, and viciously defend themselves against predators. They have huge canine teeth to aid them in these activities. Orang-utans are largely solitary. Since they seldom interact with others of their kind, they don't need to be aggressive all the time - males may fight over females in the breeding season, but often only one male at a time will find the female and mate with her. Rape is well documented in this species, however - it's a matter of opinion whether this can be called 'ferocious'.
