Octopuses can "see" light with their arms, even when their eyes are in the dark, researchers have found. When the arms of the octopus detect light, the eight-armed creature pulls them close to their body.

Because octopuses generally have a poor sense of where their body is in space, this complex instinctive behavior might help protect their arms from the pincers of predators nearby that they might otherwise not sense.

"The fact that this behavior is not a reflex, but instead controlled by higher-level cognition in the brain is fascinating," said Eduardo Sampaio, an octopus behavior researcher at the University of Lisbon in Portugal, who was not involved in the study.
