Western lowland gorilla
Gorilla gorilla gorilla
The western lowland gorilla is the largest of the living primates. Males can be up to 6 feet tall and 400 pounds while females range to 5 feet and 200 pounds. They have black to brown-gray coats that turn gray with age.
Adult males have a broad, silvery-white "saddle" on the back, extending to rump and thighs. The species has small ears and nostrils bordered by broad ridges that extend to the upper lip. Young have a white tuft of hair on the rump.
