Studies on animals’ ability to recognize themselves in mirrors have been ongoing since 1970. While humans are the only species that regularly look at their reflections in mirrors, other animals have shown signs of self-recognition in reflective surfaces. Researchers have tested many species, starting with chimpanzees in 1970. From ants to stingrays to African grey parrots, researchers have closely studied a variety of animals for their ability to perceive themselves in mirrors.
Different animals react differently to the mirror test. Some great apes, such as chimpanzees and orangutans, have passed the test, while others, like gorillas, have not yielded clear results. Monkeys often perceive their reflection as another animal, and while some have shown signs of self-recognition after training, critics argue this behavior may not be reliable evidence of self-awareness. Even an Asian elephant and rats have passed the mirror test, demonstrating their ability to recognize themselves in a mirror.
Recent studies have shown that animals like dolphins, magpies, penguins, ants
