Octopus pallidus, the pale octopus, is a species of octopus in Oceania.[1]

Immediately after hatching, the pale octopus forages, primarily on bivalves. At night it hides in rubble to surprise prey.[1] Female maturation is dependent on age as well as season.[2] Both sexes can distinguish vertical from horizontal rectangles, and gradient greys from each other and uniform grey.[3]

This species has been studied by scientists trying to determine octopus ages by stylets and pigment.[4][5]
