Of 64,000 vertebrates, only two have blue pigment

Discussion in 'Ask Jack' started by Dr. Mercola, Dec 21, 2016.

  1. The Mandarin Fish and the aptly named Psychedelic Fish have blue pigment. Other vertebrates that appear blue have layers of crystals that reflect light at shorter wavelengths to create a structural color.

    Found this interesting factoid above today and had a question for you Jack. According to Alexander Wunsch the blue pigment absorbs the red and near infrared rays. Do you think that is the reason why virtually no vertebrates have blue pigment as it would impair biological function? Also do you think people with blue eyes are at a biological disadvantage?

    Thanks!

    Think of plants: They are green. Curiously, light-loving GREEN plants reject the sun's GREEN light by reflecting it back at you, which is why they look GREEN to your eyes. Why you ask?
    Why do people far away from the equator at high latitudes have blue eyes? They are reflecting blue light from their retina to protect DHA levels. Is there another reason? Yes.

    Why do people and animals who live on the equator have dark eyes? Deep brown or black is the color that best reflects all parts of full spectrum strong sunlight. When it is always strong you do not need a ton of light to signal within the eye or skin.

    There is always a reason for what life absorbs, reflects and emits.

    Blue creates the stimulus of inflammation and red calms it. Blue pigments evolved in places to take advantage of IR-A (42% 0f sunlight) when UV A and B are poor........so this is why blue eyes show up in the Northern hemisphere in Scandinavia. This allows a tissue to by pass the Q -cycle in a poor quantum yield environment. This is a huge big deal in the eye for the RPE and the central retinal pathways because of how the water bridge between the photoreceptor and the second order neuron to be processed in the retina.

    Dan Oren, MD, PhD, researcher for Yale University and the National Institutes of Health (NIH) indicated that 50 percent of the entire blood volume in the body passes through the eyes in 40 minutes and this acts as a GIANT radiator to cool the plasma from photoreceptor to the retinal cells. This implies there is a biochemical mechanism of light involving hemoglobin within the blood, allowing the eyes to be an appropriate portal for phototherapy treatment to help with regeneration.

    Cooling water in the eye in this way induces a red shift in the spectra of water and this inactivates and quenches MOA-B enzyme, thereby increasing dopamine and melatonin levels. Yes, dopamine is a CT story too. Melatonin acts to regenerate all mitochondria with high heteroplasmy rates. Life moves in mysterious ways you do not understand light. It is magical when you do.

    The eye is not just a camera for vision but it is the governor of the sympathetic nervous system activation. BLue excites it and red calms it.

    Nature uses blue light to create a stimulus so making a pigment using it would lower the sensitiviity and specificity of blue light. So when you have a blue pigment it reflects the blue light to DECREASE the stimulus and lower sensitivity. This stimulus works big time in the eye's melanopsin/retinol system. Why? This is fundamentally how the retina measures the color temperature of incoming light to adjust mitochondrial energy flow in the central retinal pathways that SETS ALL GROWTH METABOLISM pathways in eukaryotes. So when Violet light is sparse in the environment, neuropsin, the UVA receptor in the cornea, is dormant and the eye wants to lower the blue stimulus because there is no UVA to make a larger EZ. It has to rely only on the red photons. So why did blue eye evolve in Scandinavia? To reflect some of the blue light and allow for more absorbtion of the 42% of IR-A sunlight to build the EZ to work in cells. Anything that affects the 435 -465 nm bands will alter all of growth metabolism pathways so this is why nature limits blue. Very few places on Earth have lower quantum yield, so this is why blue pigments are not common. It is a function of our star's light.

    These fish live in the Ryukyu Islands and extend south to Australia in salt water of the Pacific ocean. The climate of the islands ranges from humid subtropical climate in the north to tropical rainforest climate in the south. Precipitation is very high in these regions, and is affected by the rainy season and typhoons. These makes the water not as transparent in the photic zone. This lowers the quantum yield of this stretch of the Pacific ocean. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait between the Tokara and Amami Islands, and the Kerama Gap between the Okinawa and Miyako Islands. The islands beyond the Tokara Strait are characterized by their coral reefs which feed these fish. They got their blue pigment because the water is not transparent to UV light in this environment.
