Archerfish have captivated scientists thanks to their hunting behaviors. Using jets of water to knock insects into the water for their consumption, however, is not their only skill. Based on new research, archerfish were able to differentiate between human faces!
A computer monitor showed pictures of human faces to the fish and they were rewarded with food when they shot water at a specific image. Four fish participated in the study and the fastest one mastered the test in only 30 trials.
Building on the archerfish’s success, researchers then included 44 images of faces into the mix. Even with the increase, the archerfish still maintained up to 89 percent accuracy in identifying the intended face, thus reaping a reward.
