Understanding Cleaner Fish Intelligence

Cleaner fish demonstrate remarkable intelligence by passing the mirror test, a measure of self-recognition. This test involves marking an animal and observing if it recognizes the mark in a mirror as being on itself. Only a few non-human species, like orcas and chimps, have passed this test. Cleaner fish also recognize themselves in photos, which is linked to their territorial nature. They can distinguish between familiar and unfamiliar fish, even when their own face is photoshopped onto another body. This ability helps them defend their territory effectively.
