According to a study published in the journal Scientific Reports, scientists at the University of Oxford and the University of Queensland have discovered that a species of tropical fish, the archerfish, is capable of recognising individual human faces with remarkable accuracy. The fish were trained

FAQ

1. How did scientists discover that fish can recognize individual human faces?

Scientists at Oxford University conducted a study using archerfish that were trained to spit water at a specific image of a human face. When presented with a lineup of faces, the fish were able to accurately choose the correct face, even when the faces were presented at different angles and with different lighting.

2. Why is it important that fish can recognize individual human faces?

This discovery challenges the long-held belief that fish are not capable of complex cognitive processes. It also has implications for the way we treat fish in captivity and the wild, as well as the way we conduct research on them. The ability of fish to recognize individual humans could also have practical applications in fields such as aquaculture and conservation.

3. Do all fish have this ability to recognize individual human faces?

The study was conducted on archerfish, a species known for its ability to spit water at prey. It is unclear whether all fish have this ability, but it is possible that other species may have similar cognitive abilities.

4. How does this discovery change our understanding of fish behavior?

This discovery challenges the long-held belief that fish are not capable of complex cognitive processes. It suggests that fish are capable of recognizing individual humans, which is a highly sophisticated cognitive ability. This changes the way we view fish behavior and their ability to adapt to their environment.

5. What other cognitive abilities do fish have?

Studies have shown that fish are capable of learning, problem-solving, and even tool use. Some species of fish are also known to have long-term memory and the ability to navigate using landmarks. This discovery of fish being able to recognize individual human faces adds to the growing body of evidence that fish are capable of complex cognitive processes.
