My fourth image in this series, not too sharp but worth observance for its uniqueness:

I try to entertain my viewers with less common species, views or things and this serie thats 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!
This particular image is a young Hamadryas Baboon
Papio hamadryas a primate from the Ethiopian highlands in central-east Africa.
More to come, regardless not too many are looking forward to it... :) Mother Nature has many faces...

Hi Radu!

Is this symbiotic organism? I mean monkey + its butt :-) ? This looks SO weird! Like big, red vegetable attached to animal. Or alien fungus if you like sf more :-) I'm ready for next picture from this interesting serie my friend :-)

Another interesting shot Radu.
Hardly attractive,and one would think,a nuisance to carry around,but I guess they know what they're doing.
I wonder if humans will evolve with bum pads too.

wow that is a bad case of piles :-)

Certainly an interesting view



Hi Radu,
I cannot belive that they are used to it. He seems not to be bothered at all; in fact he looks quite comfortable. This looks almost unreal. How can they move with it? Are they actives animals or they stay still all day long? Your notes are very interesting but I still do not understand. It is my "human" vision I guess; like you said so well "nature has many faces"... Thanks,

LOL, bum pads! What a bizarre site, bully to you for showing it!
