"Elephants are one of only a handful of animals that can pass the mirror test - in other words, they can recognize their own reflection (and not think it’s another animal, as dogs and cats usually do). They tested this by placing a chalk mark on an elephant’s forehead and then showing it a mirror. The elephant investigated the mark on its own forehead, indicating it knew that it was looking at itself. The only animals that pass this test are the higher primates, the higher cetaceans (orcas, dolphines), elephants, and weirdly, magpies."
