They're chimpanzees instead of monkeys in most drawings. Chimps are used because they're the closest primate to humans - they look almost exactly like us, so people find it humorous to see them doing things that humans would do, like dressing up in clothing and using human gestures.

Hear NO EVIL See NO EVIL Speak NO EVIL
Wisdom Monkey are three monkeys that represents proverbial principle which is " see no evil, hear no evil , speak no evil "
The maxim known as see no evil, hear no evil, speak no evil comes from the three wise monkeys in 17th century Japan. The monkeys, known as Mizaru, Kikazaru, and Iwazaru, cover their eyes, ears, and mouths respectively.
The monkey that covers his eyes to keep himself from seeing evil is Mizaru. Kikazaru hears no evil because he keeps his ears covered, and Iwazaru is the monkey that keeps his mouth covered, thus he speaks no evil.
My guess (and that really is all it is :) ), is that monkey's are said to be linked to humans, but only in a very simplistic fashion (ie. they're not as advanced as humans). Perhaps this idea is based around monkeys picking up the basics of human 'rules', that we should not hear, speak or see evils. Hope that's in some way helpful :D
Oiga que ningún mal no hablar ningún mal no vea ningún mal.

It means if you are not exposed to bad things, you will not do bad things.
usually with two other monkeys, a deaf monkey and a mute monkey, it means see no evil (blind) hear no evil (deaf) and speak no evil (mute)
See no evil. Hear no evil. Speak no evil. = Se nej onda. Höra nej onda. Tala nej onda.
why on earth would you ask that?
