Octopuses demonstrate sophisticated spatial thinking by using mirrors to find food

Octopuses can learn to use mirrors to find hidden food, a skill previously observed only in vertebrates. Researchers trained octopuses to use reflections to locate food, with the animals successfully identifying the food's location about 73% of the time. This indicates they can use mirrors as tools. This finding adds to the known intelligence of octopuses, demonstrating sophisticated spatial thinking in invertebrates.
