Bald Uakari Fun Facts

Another unique feature of this creature is its extremely short tail, which is uncommon for New World monkeys. Bald uakaris are believed to have built up this remarkable coloring of their face because of malaria, which is a typical illness in their Amazon rainforest environment. Those with dazzling red appearances and a bald head are considered to be healthy, while those with paler fur have certainly contracted malaria and lack the basic natural immunity to this infection. Consequently, these debilitated creatures are usually left without mates for mating.
