Chimpanzee
Chimpanzees are the third smartest animals alive on earth with their ability to learn sign language. They are able to use the mirrors just like we humans do and try to groom themselves whenever in front of a mirror. The decision making quality makes them appear different from other animals. They seem to wait, observe the situation and surroundings, and then act based on what they have seen and considered. Problem-solving is another skill attributed to the chimpanzees. They are capable of communicating not the same way as humans do but by making noises which indicate their general mood.
