Editing Mirror test (section)

===== Pigs =====
[[Pig]]s can use visual information seen in a mirror to find food.

There is evidence of self-recognition when presented with their reflections. So far, pigs have not been observed to pass the mirror mark test, however.<ref>{{cite web | url=https://mypigfilledlife.org/adopt/f/did-you-know-pigs-are-self-aware | title=Did you know? Pigs are self aware! }}</ref>
