Few animals have passed the mirror test. Most animals are unable to recognize themselves in the mirror. Among those that pass the test are humans, apes, orcas, dolphins, and elephants. It would be interesting to see them perform the test on orcas and dolphins in water.

Pigs can use information seen in the mirror but are unable to recognize themselves. Pigeons can be trained to recognize themselves and use the mirror to see more things. Capuchin monkeys, however, are incapable of spontaneously recognizing themselves. Sadly, humans are the only animals that use mirrors for taking deceiving self-portraits to put on social networks
