Have you ever wondered why hyenas laugh? You would be surprised to know that hyenas don’t really laugh. However, there is a species of hyena called the laughing hyena. When it gets excited it makes a howling and clucking noise that sounds very similar to an insane laughter. But a hyena’s laughter does not mean that it is happy. It also makes this noise when it is feeling anxious or fearful, like when a lion is chasing it.
