They apparently also don't require crossing wires connecting each eye with the opposite brain hemisphere. Instead, the optic lobes are directly behind the eyes: http://cephalove.blogspot.com/2010/06/view-of-octopus-brain....

Also, their eye cells only detect black and white but they can probably “see” color by using non-circular pupils.

The article you linked also speculates on the main topic of this thread:
> Intriguingly, using chromatic aberration to detect color is more computationally intensive than other types of color vision, such as our own, and likely requires a lot of brainpower, Stubbs said. This may explain, in part, why cephalopods are the most intelligent invertebrates on Earth.

The visual system was often cited by proponents of intelligent design as evidence of god. But the mammalian visual system is an absolute mess. Anyone who designed that would have been fired on the spot. The octopus visual system, on the other hand, is quite elegant and efficient. If there really were an intelligent designer, the implications would be worrying.
