Fish are often said to have a three-second memory, but the brain power of fish has been considerably underestimated, according to scientists who found some fish can recognise themselves in the mirror. Their findings suggest that a small, otherwise unremarkable species called the cleaner wrasse has joined an elite handful of others to have passed the so-called mirror test, which has been used for decades as a gold standard measure of animal intelligence. Passing the test is widely viewed as an indication of self-awareness and until now the only animals to have crossed this threshold are great apes, bottlenose dolphins, killer whales, Eurasian magpies and a single Asian elephant.
