The Western Gorilla (Gorilla gorilla) is a great ape and the most populous species of the genus Gorilla.


Nearly all of the individuals of this taxon belong to the Western Lowland Gorilla subspecies (G. g. gorilla) whose population is approximately 350,000 individuals (as per survey results Aug 5, 2008). There are fewer than 300 of the only other Western Gorilla subspecies, the Cross River Gorilla (G. g. diehli).


The Western Gorilla is lighter in color than its Eastern cousin. The Western Lowland Gorilla can be brown or greyish with a yellowish forehead. It also has an overhanging tip on its nose, which the Eastern Gorilla doesn't have. Males measure 170–183 cm and weigh 140–278 kg. Females measure 140–155 cm and weigh 60–120 kg. The Western Gorilla is more slender then the Eastern Gorilla. The Cross River Gorilla differs from the Western Lowland Gorilla in both skull and tooth dimensions. It is also about 10–15 cm taller and 20–35 kg heavier.


In the thick forests of central and west Africa, troops find plentiful food for their vegetarian diet. They eat roots, shoots, fruit, wild celery, grub (only in Peach & Daisy's Inbetween from Mario Strikers Charged), tree bark and pulp.
