Octopus pallidus, the pale octopus, is a species of octopus found in the Southwest Pacific.[1]

Immediately after it hatches it will begin foraging, primarily on bivalves. At night it will hide within rubble to surprise prey.[1] There is evidence that maturation in females is not solely dependent on age, but on seasons instead.[2]

They have been able to distinguish vertical/horizontal rectangles and gradients from each other and uniform grey.[3]

This species has been helpful in learning scientific methods on identifying octopus age using stylets and pigment.[4][5]
