I try to entertain my viewers with less common species, views or things and this serie thatís about to be is definitely no exception. We all at one point or another looked at a zoo, a movie or an image of monkeys specially chimps or baboons with striking rumps, big olí red buts and no matter what the personal conclusion was the darn thing looks shocking! Depending on persona or mood it is viewed as vulgar, libidinous, comic, disgusting, interesting or strange but always a sight you just simply just cant ignore. Some people rush out or even cover the eyes of their children when such unveil their behinds. So whatís the story with the bizarre monkey buts?
First of all the correct term for it is (are you ready?) it is ischial callosity and it is defined as: a thickening of the skin overlying a posterior section of the pelvis (ischial tuberosity); found in the Old World monkeys and some apes. Or in 1913 Webster said: one of the patches of thickened, hairless, and often bright-colored skin, on the buttocks of many apes, as the drill.
First impression is to believe that t has to do with animals being in heat and these ischial callosities acts as extreme visual signals to attract attention. Well biologists came to the conclusion that they are simply bum-pads. Which makes lots of sense if you think that you can pretty much find them on the terrestrial monkeys & apes: baboons, macaques & the chimpanzee. So it is an evolutionary development that helps them sit on surfaces for long periods of time. It also enhances its color greatly during mating season. So both opinions were true!
Third image on this series is an amazing primate from the baboon family, a male mandrill Papio shinx, .The Mandrill (Mandrillus sphinx) is a primate of the Cercopithecidae (Old-world monkeys) family, closely related to the baboons and even more closely to the Drill. Both the Mandrill and the Drill were once classified as baboons in genus Papio, but recent research has determined that they should be separated into their own genus, Mandrillus. The Mandrill is the world's largest monkey species. The word mandrill means "man-ape".Males can weigh up to 60 lb (30 kg), females about half as much. They can grow to be about 1 m long (39 in) and can survive up to 25 years in captivity. The Mandrill is found in the tropical rainforests of West Africa (Southern Nigeria, South Cameroon, Gabon, and Congo). It is a social creature and may be found in groups ranging from 5 to 50 individuals, led by an older dominant male. Six to seven of these groups may come together during the dry season to form a troop of over 200 individuals.

Another amazing example of extreme ischial callosity.
Well done, Radu.
You are going to end up with the world's most complete catalog on the subject.
Excellent POVs and colors.
TFS. : )

I like this series :o)
"So it is an evolutionary development that helps them sit on surfaces for long periods of time." Spending 9 hours a day sitting on an office chair I wonder what my evolutinoary development would be till I retire ! lol...
haha, the monkeys just getting weirder each time! What is that tail!? Good that u included both views, makes the picture more interesting so i don't have to imagine how its butt looks like (not that i like to imagine about butts....)
Well it seems a little soft to me, and i might be tempted to play with the color saturation a little. But i think the naturalness works well here. :)
