The video, filmed at Twycross Zoo at Atherstone, England, shows the two bald chimps, chasing and hitting each other along with dozens of others. The two chimpanzees with alopecia had caused a fight to break out between a group of apes at the zoo.
The pair are believed to be father and son and their scrap leds the entire group of chimps becoming involved.
Speaking about the ferocity of the fight, the video uploader later wrote online: “A few scratches and some minor wounds and probably a few more scars.”
Scientists believe alopecia can be induced in chimpanzees due to stress or trauma, which can also happen to humans.
