Elephants are among the few animals that can recognise themselves in a mirror.

The longer version

Passing a mirror test means an animal uses the reflection to investigate itself rather than treating it as another individual. The classic procedure marks the body somewhere visible only in a mirror and watches whether the subject touches the mark.

Elephants, along with great apes, dolphins and magpies, behave in ways consistent with that understanding, using the mirror to explore parts of their own bodies. The capacity is linked to large brains, complex social life and the ability to track individuals over time, since recognising others and recognising oneself draw on overlapping cognitive machinery. Failure in other species does not prove absence of self-awareness, only that the test may not suit their senses.
