Scientists recently discovered that they can do something else even cooler than catch prey with jets of water. Even though archerfish have a primitive brain, they can recognize different human faces. What?
Here's how it went down. Scientists at the University of Oxford and the University of Queensland showed four archerfish a images of human faces via computer monitor and trained them to spit water at one of them. Not nice, but hey, it's for science.
Once the archerfish recognized that face, they were then showed images of new faces along with the "learned face." The archerfish aced the test with flying colors, recognizing the"learned face" 81 percent of the time.
The scientists conducted a second test using four different archerfish and gray-scale images of human faces. These smartypants fish fared better than the first batch and recognized the faces with 86 percent accuracy. Not bad for an organism with a primitive brain.
