I recall reading an interesting theory on the mirror test: some animals for whom sight is a more secondary sense might fail a mirror test, but could potentially self-identify using other senses. Take dogs for example: their sense of smell is much much more primary than their sense of sight. So while they may fail a mirror test, they may be more adept at self-identification by scent.
