When you first think of baboons, what comes to mind? It's OK. It's the same thing most of us think of: their, ahem, big red butts. So let's just get this out of the way upfront. Why are baboon butts red? First, to clarify, the swollen red bottom happens only on female baboons. It's a sign that they're ready to mate, so yes, it's about sex.
And when we say their bottoms are swollen, we do mean swollen. LiveScience reports that the swelling has been recorded between 4 and 6. But all this exaggerated swelling doesn't necessarily have any real function or benefit for baboon baby-making.
The baboons with the reddest rumps didn't attract the most mates, or have the most sex, according to a study published in the journal Animal Behaviour. The female baboons with the most swelling didn't seem to have better odds of their offspring surviving past infancy, either. The male baboons, it seems, were more interested in how long it had been since the females had their last infant than how red their rumps were.
Females that had older infants and weren't nursing, regardless of swelling, were the ones more likely to mate. So again, what's the deal with the red bums? It appears it's simply a function of ovulation. For 10 to 20 days each month, this hind area swells up, and reaches its peak when the female is most fertile. Then it returns back to normal. We can unfortunately?
They even get callouses on their bums from sitting on them all the time, similar to the callouses dogs develop on their elbows from lying down. Now that we have all the baboon butt talk out of the way, let's answer some other questions about baboons, because they are cool regardless of their ugly rear ends.
Baboons Papio are primates and they're one of the 23 types of Old World monkeys , so they do not have prehensile tails. That means, unlike their New World monkey cousins in South America, they can't use their tails to swing from trees. They're also the world's largest monkeys. So with their size — and the fact that they don't have a tail that can help them out much — baboons tend to spend most of their time on the ground, using both their feet and hands to walk, rather than in trees.
Most scientists agree that there are five species of baboon. Interbreeding is common , so there are hybrids, which makes strict classification tricky. Baboons are indigenous to sub-Saharan Africa and are found widely throughout the southern half of the continent. Hamadryas baboons are the northernmost species. The swollen red bottom of a female baboon has long been thought to be an irresistible come-hither signal for males. But now, a new study suggests that male baboons are much more sophisticated than that.
In fact, a male baboon's Papio cynocephalus motivation to mate with a female is based more on the length of time since her last pregnancy than on the size of her derriere, scientists have found.
The female baboon's famously red bottomis a sign of sexual readiness; when female baboons ovulate, their butts swell, making it clear to available males that they are fertile. Evolutionary psychologists have even argued that human males share some of the love of red that drives our primate cousins, suggesting that red lipstick and clothing mimics the function of a red baboon butt.
However, research suggests the line between the color red and sexual appeal may not be quite so straightforward. Fitzpatrick and her colleagues wanted a precise measurement of female rump swelling, to see if bigger bottoms did, in fact, correlate with more mating and infant survival. What is a group of baboons called? What is the most dangerous monkey? As far as physically I would say baboons are potentially The Most Dangerous Ones you're likely to run into.
They are extremely strong extremely large they have huge teeth and are aggressive. What is the strongest monkey? That would be the Mandrill, whose males are the most massive of all monkeys, with individuals having been weighed at up to 54kg pounds. Mandrills tend on average to be slightly shorter than Chacma Baboons, but are so heavily muscled that they outweigh them regardless.
What type of monkey is Abu? Do mandrills eat humans? Grass, fruit, seeds, fungi, roots and, although they are primarily herbivorous, mandrills will eat insects and small vertebrates. Leopards, crowned hawk-eagles, chimpanzees, snakes, and humans. What does a baboon look like? Baboon bodies are 20 to 40 inches long, not including substantial tails of varying lengths.
Like other Old World monkeys, baboons do not have prehensile gripping tails. But they can and do climb trees to sleep, eat, or look out for trouble. They spend much of their time on the ground. Are mandrills violent?
