For a moment there, that headline had me thinking that school kids who happen to be weird have colorful gardens and are showing these gardens to octopuses.
[cephalopds] are colorblind – their eyes see only black and white – but their weirdly shaped pupils may allow them to detect color
Do PR people ever think about the awfulness of the drivel they write? I see the point the author is trying to make here but writing self-contradictory sentences is not the wright approach.
Cephalopods, long thought to be color-blind, may in fact be able to detect color....
Although the retinas of cephalopods cannot detect different colors, new research suggests they may be able to detect color another way.
...etc.
What a beautiful hack by nature. I wonder if you could create a lens with a similarly shaped pupil/iris and see the chromatic aberration in a black and white camera correctly focused on the output. Would make for a fun weekend project :)
The black and white film is still only going to record black and white images ... The "may be able to judge color" part of the theory requires "processing". You might however be able to digitize your black and white photo and "colorized" it.
Octopus does not originate from latin, but instead greek. So it would be octopodes[0], however, we all speak english, so octopuses is fine. Or, you know, use what you want because english isn't prescriptive...
Fascinating tidbit for those who check the comments first:
> 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.
Can someone tell me if I am understanding this right? If not, can you clarify?
This is how I understood it:
They don't have different cones cells for detecting color. Instead, their pupil is more like a slit, causing light to be diffracted, not unlike a prism. Because of the diffraction, different wavelengths of light fall on different areas of the retina. Their brain is mapped as such that they understand the location of the light as the color. Moving the eye around helps them refine this information.

Wouldn't a behavioral test immediately reveal that they are not colorblind?
I'm curious about the scientific process here.
