I prefer to call them cuddlefish.

Nature's clown fish

Cuttlefish are fascinating. From Wikipedia [0]:

"Cuttlefish are able to rapidly change the color of their skin to match their surroundings and create chromatically complex patterns, despite their inability to perceive color, through some mechanism which is not completely understood. They have been seen to have the ability to assess their surroundings and match the color, contrast and texture of the substrate even in nearly total darkness."

I read that cuttlefish is actually able to perceive color even if they only have one kind of receptors on their retina. This is thanks to very oddly shaped pupils which focus different wavelenghts in different parts of the retina.

More on this theory; https://www.science.org/content/article/how-colorblind-cuttl...

The w shaped pupil lets them see the polarization of light too, wild stuff.

Something I have always wondered about articles on research papers. Is it the norm or standard that they always consult and expert in the same field that wasn't part of the research? why is this?

I have seen this in many physics articles too. I am not against it as it seems purposeful.

Nature often does this in their news division: someone qualified but not connected. It's good practice!

Some books I cannot help but recommend:

Non-Fiction:

- Sy Montgomery: The Soul of an Octopus

- Peter Godfrey-Smith: Other Minds

Fiction:

- Shelby Van Pelt: Remarkably Bright Creatures

- Ray Naylor: The Mountain in the Sea

They are each fantastic, and anyone curious or a fan of cephalopods should read 'em.

Yes, they are fascinating creatures, but I'd be willing to bet that Kyle would still have preferred vanilla paste..
