In a recent study, archerfish identified human faces by squirting water at the correct image on a screen. In the wild, archerfish use their spit cannons to knock insects and other prey into the water to eat. But in the lab, scientists used food to train these fish to use their spitting abilities to help us better understand animal cognition. The study revealed that archerfish could be trained to recognize a 3D rendering of a human face. In the study, the archerfish received food when it spat water at the correct face. The fish were mostly able to recognize the faces when they were rotated by 30, 60, and 90 degrees. The study showed that fish are capable of performing complex tasks in similar ways to animals with larger brains. It turns out that fish can do a lot of things that most people wouldn’t think they could. • ➡ Subscribe: http://bit.ly/NatGeoSubscribe • #NationalGeographic #Archerfish #Fish • About National Geographic: • National Geographic is the world's premium destination for science, exploration, and adventure.
