This is Cercopithecus lomamiensis, a new species of monkey discovered in Africa (one of only two new species discovered in the past 26 years). It has a creepy, human-like face and a bright blue ass. Kind of like a Na'vi. There's a worthwhile shot of one's ass and balls after the jump because regret is something we all have to learn to live with.
Hit the jump and exercise your coping mechanisms.
Thanks to Sicero, who agrees all animals should have brightly colored butts so the zoo is like an ass rainbow.
