NIGHT MONKEY

The night monkeys, also known as the owl monkeys or douroucoulis, are the members of the genus Aotus of New World monkeys. The lifespan of a wild night monkey is unknown; however, they have a lifespan of 20 years in captivity. The total population of night monkeys is similarly unknown, as the monkeys live near the canopies of deciduous forests, making counting the monkeys very difficult. Night monkeys constitute one of the few monkey species that are affected by the often deadly human malaria protozoan Plasmodium falciparum, making them useful as non-human primate experimental models in malaria research. Night monkeys have big, brown eyes and therefore have increased ability to be active at night. Their ears are rather difficult to see, and their genus name, Aotus, means "earless" because of this. There is little data on the weights of wild night monkeys.
