Gorillas play the childhood game of "tag" just like humans do. They even give the weaker or younger gorillas advantages by running more slowly or letting them win sometimes. Scientists believe that their playing tag is a way of learning the rules of social interaction.
More facts about gorillas:
- Another important social interaction for gorillas is grooming. In fact, they can become so relaxed by it that they go into a trance-like state.
- Gorillas laugh when they are tickled and make crying sounds when they are sad, though they do not produce tears like humans do.
- When gorillas drink, they soak the backs of their hands in water, then suck the water out of the fur.
