Smart fish can recognise human faces, scientists find

Oxford University study could shed light human brain function and whether facial recognition is an innate or learned ability

A tropical fish can tell one human face from another despite lacking a brain section that homo sapiens and other "smart" animals use for this task, scientists said Tuesday.

The astonishing ability was demonstrated in experiments with eight archerfish, a tropical species best known for spitting pressurised water jets to shoot prey out of the air.
