Lateralized eye use in Octopus vulgaris shows antisymmetrical distribution

Article Abstract:

Octopus eyes are on the sides of the head, and these animals prefer monocular to binocular vision. Preferential eye use is determined by recording the time that the octopuses watched a stimulus outside the tank while holding on to the front glass of the tank. Thirteen of 25 subjects were highly significantly left-eyed, 10 highly significantly right-eyed, and two showed no preference.
