Not many animals recognize themselves in a mirror. The ability to sense one’s self, or self-awareness, is delegated to only a few members of the animal kingdom, including human beings. The mirror test is performed when a mark or object is placed on an animal, and the animal is put before a mirror so he or she can see the mark. If the animal starts to search its body for the mark it passes the test, because it recognizes that the animal in the mirror is itself.
Elephants have both passed and failed the mirror test depending on the individual, states Scientific American. Three of these animals were tested, two of which failed to explore their bodies for the mark. However, based on their movements, both of them recognized themselves in the mirror.
Gorillas are another animal that have mixed results when it comes to the mirror test. Although most fail the test, experts hypothesize that this is because making eye contact with others is a social taboo, so they never progress to actually examining themselves in the mirror.
The orangutan is another primate that demonstrates self-awareness. It was an orangutan that first spawned the mirror test idea back in 1838, according to World of Lucid Dreaming.
