Fun fact, this is actually the first documented proof of chimpanzees reacting to music in a rhythmic way

Rhythmic swaying induced by sound in chimpanzees (Pan troglodytes)
Significance
In humans, listening to music induces rhythmic movement, suggesting a close connection between the auditory and motor areas in the brain. Sound also induces rhythmic swaying in chimpanzees. Male chimpanzees are more responsive to sound than female chimpanzees, consistent with previous research on acoustic communication in their patriarchal societies. We also found an effect of beat tempo on movement periodicity and tendency to seek the sound. These results suggest that prerequisites for music and dance are deeply rooted and existed in the common ancestor shared by humans and chimpanzees, approximately 6 million years ago.

Abstract
Music and dance are universal across human culture and have an ancient history. One characteristic of music is its strong influence on movement. For example, an auditory beat induces rhythmic movement with positive emotions in humans from early developmental stages. In this study, we investigated if sound induced spontaneous rhythmic movement in chimpanzees. Three experiments showed that: 1) an auditory beat induced rhythmic swaying and other rhythmic movements, with larger responses from male chimpanzees than female chimpanzees; 2) random beat as well as regular beat induced rhythmic swaying and beat tempo affected movement periodicity in a chimpanzee in a bipedal posture; and 3) a chimpanzee showed close proximity to the sound source while hearing auditory stimuli. The finding that male chimpanzees showed a larger response to sound than female chimpanzees was consistent with previous literature about “rain dances” in the wild, where male chimpanzees engage in rhythmic displays when hearing the sound of rain starting. The fact that rhythmic swaying was induced regardless of beat regularity may be a critical difference from humans, and a further study should reveal the physiological properties of sound that induce rhythmic movements in chimpanzees. These results suggest some biological foundation for dancing existed in the common ancestor of humans and chimpanzees ∼6 million years ago. As such, this study supports the evolutionary origins of musicality.

While I have this link:


I used to say "man, these things are so alien, they might actually be from another planet," but I only thought that because it's so different from my norm. I don't regularly encounter creatures with ballooning color-changing skin cells, but it's nice to know they exist.
