Eyes of an octopus
They say that cephalopods such as cuttlefish & octopus have well-developed eyes and acute vision. Despite this, they are said to be colour-blind. A hammer octopus, Octopus australis, is said to darken its eyes to appear bigger to potential predators. The octopus featured in the photo above could be either O.pallidus or O.berrima.
