This is the second largest group of mountain gorillas. It has 35 individuals with four silverbacks. It was originally studied by Dian Fossey and lives on the slopes of mountain Karisimbi. The most particularity of this group is having rare twin gorilla born twice in the same group.
The last event was on 19.05.2004 when 12 years old female Nyabitondore gave birth to twins male and female and on 27.05.2011; another old female Ruvumu produced two twins male and female. All have been successfully raising these twins. Those of 2004 are now 8 years old and others of 2011 are now 8 months. These might be the first ever twins to survive in the history of Mountain gorillas. However, Susa family has recently separated to form their own group of 17 individuals.
