9. Noisy night monkey
Most normal monkeys are active during the day, but not members of the Aotus genus. Known as night monkeys and owl monkeys, these ones have evolved large eyes to help them snatch flying insects, move through trees in the darkness, and watch infomercials on TBS.
The best night monkey is Aotus vociferans, the noisy night monkey, who keeps neighbors awake with his racket of hooting sounds.
