A scientific article showing that octopuses are capable of locating prey that is hidden from their direct view but reflected in a mirror, and of navigating toward these visually hidden locations that are spatially aligned with the location of the reflected prey. These findings extend the ability to use mirrors to invertebrates, demonstrating that cephalopods can use mirror reflections for spatial navigation.
