Saving the Species
Western lowland gorillas, although still the most abundant of the four types of gorillas, are listed as critically endangered by the International Union for Nature (IUCN), with threats including poaching and disease. Conservationists estimate that the total population has declined by more than half over the last 25 years. Philadelphia Zoo does its part to help save this species by participating in the Gorilla Species Survival Plan.

Famous Moves
You may have seen a gorilla beat its chest while visiting the Zoo. Gorillas of all ages and sexes beat their chests, and it is often an indicator of excitement or play for the young. Adult males also chest beat for these reasons, and as a display to intimidate potential threats to the family.
Other displays from a gorilla can also include ground beating, tearing up of vegetation and short sudden sideways rushes. These are mostly for show; gorillas are peaceful animals, with chest-beating and other displays showing how big and strong they are, so that actual fights are seldom necessary. The largest and heaviest primates, gorillas can weigh 400 pounds or more.
Philadelphia Zoo is home to a family troop that includes Motuba, Honi, Amani, Kira and Ajabu.
