Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing they could use a mirror as a tool rather than simply reacting to a reflection.

A new Dartmouth study shows octopuses can use mirrors to find food out of sight, demonstrating spatial cognitive abilities. The results are published in Current Biology.
