A rich man refused to help a poor traveler the night before New Year’s. The Japanese macaque, aka the snow monkey, has a colorful folk tale from Okinawa about their red behinds. They’re adaptable, highly intelligent, cute, very social – and both males and females have red or bright pink faces and butts. They are the second most successful primates in the world, with humans being the first. The size and shape of buttock swellings differ greatly from one chimp to another.Ģ3 species make up the group of monkeys known as the macaques (pronounced ma KAKS). Butts not only signal if a female is ready for mating, but also let a chimp know if this is a relative, friend, enemy, and how healthy they are. It’s thought that our ancestors also recognized others from their butts, but lost this when we began walking upright.Ĭhimpanzees also recognize faces, but they also remember butts. The red butts let males quickly know that they are ready for action.Ī 2016 study has also discovered that both male and female chimpanzees recognize other chimps by their butts in the same way that humans recognize individuals by their faces.īutts are quite prominent in a chimpanzee’s world. Like many female monkeys, female chimp behinds get red and swollen when they are fertile and advertising for a mate. Both live in Africa.Ĭhimpanzees or chimps are technically apes and not monkeys since they lack tails, but they are still primates with red or bright pink bottoms. There are two species of chimps, the regular and the bonobo. Females find these colorful males irresistible. The highest-ranking male always has the highest testosterone levels in the troop. It’s this rise in testosterone that causes the drastic color changes. Why is this so? When a male wins a fight to become the leader of the troop, his testosterone levels rise. Sometimes faces will also have splashes of yellow or light purple.Īll the other males in the troop are far less colorful. Their faces are also more colorful, with a bright red stripe going up a bright blue or white face. Some will even get shades of light purple. They, too, like baboons, live in Africa.įemales also have swellings of the buttocks when they are ready to mate, but their behinds pale in comparison to the buttocks of the dominant male.ĭominant males have spectacular technicolored butts. Now, they are considered a separate species from baboons. However, they only have a stub of a tail. Mandrils were once thought to be a kind of baboon since they share many physical features. They also did not have a better chance of keeping a baby alive to adulthood. This study also shows females with bigger butts did not attract more mates. It was once thought that the bigger a bottom the female baboon had, the healthier, more desirable, and more fertile she was. Males also did not like females who were still nursing. Males prefer to wait until a female has gone through more than one cycle before mating. They know and remember when a particular female was last pregnant. Male baboons pay close attention to the health of all of the females in their troop. Not only do the butts get bright red, but they become hugely swollen.Īlthough swollen red butts were thought to be the ultimate aphrodisiac for baboon males, a 2015 study has shown that it takes more than a red booty to get a male baboon’s attention. Females produce the most spectacular red bottoms when they are in season. They are the hamadryas, the olive, the yellow, the Chacma, and the Guinea.Īll of them have red or dark pink bottoms. There are five species of baboons living in Africa and Arabia. The highest-ranking mandril male has a multi-colored butt, which includes red, blue, yellow, and sometimes purple. Species of monkeys having red or bright pink butts include baboons, Japanese macaques, Rhesus macaques, Celebes crested macaques, chimpanzees, and mandrils.
