We have discussed some amazing examples of how species control their color (here and here, for example) and how such technology in nature has inspired engineers creating advanced new technologies such as low-power video displays. Now new research is helping to explain how squids and octopuses change color and it is amazing. Read more

Of note: Caribbean Reef Squid: A Conundrum for Neo-Darwinian Evolution? – by Melissa Cain Travis – February 20, 2013
Excerpt: A spectacular example of a creature that seems to utterly defy naturalistic explanation is the Caribbean reef squid, known by the scientific name, Loliginidae sepioteuthis. These highly intelligent cephalopods (the broader animal category that includes squid, octopuses, and cuttlefish) utilize a stunningly sophisticated mode of communication that is based upon lightening-fast changes in the colors, patterns, and textures they exhibit in their skin. The squid have dynamic structures in their skin called chromatophores that are used to cause these changes. The squid also has special structures that reflect or absorb incoming sunlight to help form all the various skin colors and patterns. The iridescent areas are called iridophores.
In less than 30 milliseconds (yes, milliseconds!!), and in response to a visual cue, the squid can purposefully change its color and pattern to communicate with another squid, court another squid, stun their prey, or to try and ward off or confuse a potential predator. Many of the color/pattern displays include certain arm postures, as well. The squid can manipulate its color/pattern display in order to make it appear to move across their body.

David Gallo: Underwater astonishments – video
http://www.ted.com/talks/david.....ments.html
David Gallo shows jaw-dropping footage of amazing sea creatures, including a color-shifting cuttlefish, a perfectly camouflaged octopus, and a Times Square’s worth of neon light displays from fish who live in the blackest depths of the ocean.
Of semi-related interest to this amazing ability of some creatures to precisely control the reflection of light in such a myriad of amazing ways, is the little known fact that humans, and all living creatures whilst they are alive, emit light instead of merely reflect it:
It is interesting to note that the Bible, some 3 or 4 thousand years before it was even discovered that the face emits more light than the rest of the body, recorded as such,,
Moreover, this light is emitted from humans at a very deep quantum level:
Moreover, the Shroud of Turin bears witness to the fact that the Face of Christ emitted more light than the rest of His body during His resurrection from the dead:
As well the fact that Christ’s Face was brighter than the rest of His body was also recorded a few thousand years before it was (re)discovered on the Shroud:
Science has recently confirmed that the light that was used to form the Image on the Shroud was extremely powerful
and the light was also extremely precise:
Moreover, many Near Death Experiences give testimony to being in a ‘body of light’ whilst their temporal body is dead
Please compare the similarity of the optical effect, noted at the 3:22 minute mark of the following video, when the 3-Dimensional world ‘folds and collapses’ into a tunnel shape around the direction of travel as a ‘hypothetical’ observer moves towards the ‘higher dimension’ of the speed of light, with the ‘light at the end of the tunnel’ reported in very many Near Death Experiences: (Of note: This following video was made by two Australian University Physics Professors with a supercomputer.)
i.e. That a higher dimension of light exists above this one is confirmed from special relativity!

Music:
You can tune a piano, but you can’t tuna fish.
Some things never change.
We can tuna fish (solid or chunk light- in water or oil). 🙂
