Gorilla beringei beringei
Mountain Gorillas are listed as critically endangered - less than 900 of these gentle giants remain today.
They occur in the Virunga Volcanoes area between the DRC, Rwanda and Uganda and in Bwindi Impenetrable Forest in Uganda.
Many threats still remain - people pressure, deforestation, poaching and human disease.
Huge international conservation efforts are helping to protect their habitat.
Ecotourism plays a large role by channeling millions of dollars into developing surrounding communities and protecting the integrity of the National Parks the Gorillas live in.
