NOTE: This is not a fictive image but the real image of an animal. However two views have been taken and were stitched together into one for better representation side by side! Now read the rest and enjoy!
I try to entertain my viewers with less common species, views or things and this serie that’s 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 ol’ 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 what’s 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 time the image is in fact a stitch of two images of exact same animal, one direct posterior view and one dexterous semi-profile from the back. The specie here is a black crested macaque (Macaca nigra) an Indonesian primate endemic to only north-east Celebes (Sulawesi) archipelago. Local language names are “ kera yaki ” or “monyet hitam ” meaning black ape. They look quite impressive, even outside their extreme example of ischial callosities, like you see portrayed here. They look like little gorillas, in almost everything they do, males even resemble the silverbacks and have crests and are just as aggressive and territorial. Very little is still known about this specie but currently famous primatologists are in the field by the lowland tropical forests surrounding volcano Tangkoko to much different Gunung Sibela the high up, mountainous rainforest sometimes over 2000 meters high! Crested black macaques are mainly frugivorous but they consume a huge variety of foods including seeds, leaves, flowers, pith, herbs, grass seeds, fungus, bird eggs, birds, and small vertebrates such as lizards and frogs.

Hi Radu,
What a funny pose, and how beautifully captured. Great colors and stunning details and all topped of by a very informative note. Good control over the exporure considering the huge difference between light and shadows.

They really look like they were posing for you :)I like the fact that the one at the right is looking at you. Interesting notes, without them, I would never have known what was the utility of such big buts :-) Thanks,

Those are definitely extreme butts, Radu.
An amazing sight, for sure.
Those monkeys look unfamiliar.
So they are black crested macaques?
So many species of primates.

LOL - lovely!

Very amusing and a great shot too. Interesting POV :-)

Excellent details and colours.



Picture not suitable for all viewing ages! (kidding) man, this is quite disgusting and disturbing. They are both showing off their bums!? Not very nice ones too! Very interesting and good note! This really made me cringe!

Impressive in all the senses captured POV Radu, with good sharpness and an framing something adjusted.

I like it a lot: composition (with stich included), POV, DOF, sharpness, focus, color, lighting, background, notes.

I like it: framing.

I don't like it: the lack of the values of the image.

Nice job.
TFS and greetings... Ricardo

Hi Radu,
Great shot ,some thing unusual and extra ordinary.I never knew that some animals are born with sofas fixed to their bottom.Joke part,the photograph is excellent,with good colours,DOF and POV.

Wow, great POV... I'm a biologist but there some things in nature that do not stop to amaze me...
Best greetings,

Hi Radu,
Very cool image and interesting capture!

Oh My Gosh. I started my diet today, but after seeing this, I'm actually very pleased about myself.

If mankind walked around like that we all would never get any work done. I'd laugh all the time.

Hilarious but very interesting to say the least.
