Another endangered monkey species on this list is the Uakari Monkey, an animal that is incredibly identifiable by its bright red face and bald head – not unlike an old man with a terrible sunburn. This particular primate was named after the Uakari tribe that once lived in the Amazon but has now unfortunately become extinct. However, worrying trends show that the monkey is on track to follow its namesake as extensive deforestation has destroyed much of their natural habitat, making it difficult for the animal to forage and nest. Some of its populations have also been vulnerable to illegal hunting. Native to western Amazon rainforest, the Uakari Monkey plays an important role in seed dispersal and is particularly crucial for its ability to transport seeds at a greater distance than smaller animals.
