How do western lowland gorillas look like?

Although western lowland gorillas are the smallest of the four subspecies of gorilla, they still have exceptional size and strength.

• The average weight of an adult male western lowland gorilla is 140 kilograms.
• The average weight of an adult female western lowland gorilla is 90 kilograms.
• Adult male western lowland gorillas stand up to 5 feet tall
• Adult female western lowland gorillas stand up to 4 feet tall
• A fully grown male can weigh up to 181 kilograms and stand up to 6 feet tall.

The Western lowland gorilla can also be distinguished from other gorilla subspecies by their brown-grey coats, longer arms, auburn chests, and a more prominent ridge along their brow. Their skulls are wider, ears are smaller and their brow ridges are more pronounced.

Infant gorillas possess a tuft of white hair on their backsides, and older gorillas can get streaks of silver in their hair. Western lowland gorilla also has proportionately large hands with nails on all digits, similar to those of humans, and very large thumbs.

They have short muzzles and large nostrils. These gorillas often stand upright, but walk in a hunched, quadrupedal fashion, with hands curled and knuckles touching the ground.

This movement style needs long arms, which works for western gorillas since the arm span of gorillas is larger than their standing height.
