That is an exaggeration of a gorilla. Gorillas never get that big. Gorillas can not swim or climb trees because they are too big and heavy. Gorillas walk on the ground with their knuckles on the ground and their fingers clenched to their fist. Most of a gorilla's diet is a lot of rough stringy plants.
Gorillas have a very similar yawn to humans.
They can also shed tears and burp, hiccup and cough. There is a gorilla that is all white named Snowflake. His kind is very rare. There are only two that we know of in the world today. He is not an albino but just a very rare natural white gorilla.
