Fish can’t recognise faces if they’re upside down – just like us, New Scientist (July 26, 2017)

Are you good with faces? So is the Japanese rice fish – at least, it is if the faces are the right way up. Just like humans, the tiny fish has no problem recognising faces orientated the usual way, but, again like us, it struggles when they are inverted. The finding indicates that the fish may have developed a unique brain pathway for face recognition, just as humans have.
