Noisy Night Monkey

The night monkeys are the members of the genus Aotus of New World monkeys (monotypic in family Aotidae). The only nocturnal monkeys, they are native to Panama and much of tropical South America. Night monkeys constitute one of the few monkey species that are affected by the often deadly human malariaprotozoan Plasmodium falciparum, making them useful as non-human primate experimental subjects in malaria research.
