Mountain gorilla

According to The I-Spyder Book of Earth Creatures, the mountain gorilla — formally known as Gorilla beringei beringei —was a shy herbivore that lived in forests. Its natural habitat was in the north-central African nations of Rwanda, Uganda and the Democratic Republic of Congo. Males were often twice the mass of females. When adult, males could be further distinguished from females by the presence of silver fur on their backs, leading to the secondary name, silverback.

Unlike humans, mountain gorilla's arms were longer than its legs, which forced the animal to adopt either a four-limbed approach to walking or to walk on two legs with its knuckles dragging.

The creatures were last seen on Earth in 2030, and had been killed off because their habitat was destroyed and they were hunted by humans.

They had an I-Spyder point value of 500. (NSA: The Last Dodo)
