The gorilla is considered to be a highly intelligent animal on a similar level with humans and dolphins. The real extent of the gorillas intelligence is unknown, however one gorilla bred in captivity was successfully trained in human sign language.
The senses of a gorilla are very similar to the senses of the human and include hearing, taste, touch, smell and sight, although the sight of the gorilla is not quite as acute as the sight of the human but the gorilla is thought to be able to see in color vision.
The gorilla spends the night sleeping in a nest which the gorilla makes out of leaves and other plant materials. The nest of the gorilla is shaped like a bowl and is where the mother gorilla will sleep with the baby gorillas.
Despite what many people think, the gorilla is not an aggressive animal as the gorilla is known to be shy and peaceful in nature. The gorilla will generally only display aggressive behavior towards another animal if the gorilla feels under threat but the gorilla will only tend to make lots of noise rather than attacking an unwanted intruder.
