WHY are there no blue ANIMALS in our world?

Just think, humans are unable to see blue tigers.

There are no blue dogs, no blue squirrels, bears, lions, or blue cats. Even though it is called a blue whale, it is not really blue. Why is that?

If we look closely, we can see that the sky is blue and the water in the sea is not blue, but we can see it as blue.

Although blue is a colour close to our life, this blue colour is also the rarest colour in our nature.

Imagine the feeling that comes to our mind when we see a blue animal among the ordinary animals that we just see.

That animal is really beautiful

So, the reason for this is that blue is a rare colour in nature, so when we see it, we get wonderful inspiration.

So why did our nature create the animals and plants of this world with less blue colour?

you will know that blue colour animals do not exist in this world, it is an illusion that deceives the eye.

To understand the scarcity of blue in nature, we must first delve deeper into colour science.

When light interacts with an object, it perceives colour.

The colours we see are wavelengths that are reflected back to the eyes, so when we see something blue, it is a colour corresponding to a shorter wavelength of the visual spectrum.

Why couldn't plants be blue?

Producing blue pigments for plants is complicated because plants need large molecules to absorb long wavelengths.

It is a complex process

This makes it difficult for plants to perform photosynthesis.

So, only less than ten percent of the three hundred thousand species of flowering plants have blue flowers.

Not only that, because plants absorb blue light for photosynthesis, blue leaves do not exist.

So some leaves look blue because of the reflection of light from them, not because of the blue colour in them.

So that means no blue leaves.

Thus, a plant cannot grow if it begins to reflect blue light.

For this reason, we supply blue lightbulbs to plants in planted tanks and greenhouses.

Because blue is an essential colour for plants,

Therefore, no plant reflects the blue color.

Why couldn't animals be blue?

Animals can't make blue either.

But the birds are blue and I will talk about that later.

So animals cannot be blue because plants do not make blue. We know that the colour of our animals depends on the food we eat.

So we can take good care of this. When we look at the flamingo bird, if they are in places where they can eat a lot of shrimp, the colour of those guys is very pink.

The food they eat also affects the colour of such animals, but animals in this world do not have food with blue pigments. I am not talking about the blue food that people make with colouring.

Anyway, there are blue butterflies

Animals like the blue mogo butterfly and the blue jay look blue, but believe me, they are not really blue.

They appear blue to us because of the light-reflecting nature of their wings.

So scientists have observed this with a microscope

So in the arrangement of the butterflies' feathers, they can reflect the blue colour.

That's why we see them as blue.

Actually, what happens here is that the blue color is reflected and shown to us by the falling light.

how's that? There are no real blue butterflies.

We don't see blue except for birds and butterflies and some insects.

Nor any other animal.

This happens because there is no blue food in the environment as mentioned before.

Most colors in animals are produced by pigments.

So they are chemical compounds that absorb certain wavelengths of light and reflect others.

However, the blue pigment is almost absent in the animal kingdom.

Instead, the blue color we see in birds and butterflies is usually the result of structural coloration, not the color they get from food.

The blue color of birds is shown by their structural coloring or structural coloration, so scientists have discovered that this is a physical phenomenon and the microscopic structure of feathers interacts with light to show us the blue colors we see.

So when you look at it like that, the birds are not really blue, the blue color is shown to us based on the arrangement of their feathers.

When a blue feather grows, the keratin in the feather cells separates from the water.

When these cells die, the water evaporates and is replaced by air.

So that way only keratin and he pockets are left.

This is a complex structure.

When light hits this, it blocks the red and yellow wavelengths and reinforces the blue wavelengths, making it appear blue to our eyes.

That is why we see blue feathers.

The story of frogs is a little different when we say frogs, snakes are also included.

So they have a condition called Aposematism Coloration. Frogs and these snakes are helped by their blue color to scare off predators and find a suitable partner for reproduction.

Chromatophores is especially responsible for the blue color from them.

So these contain small crystals saturated with air and compounds like hypoxanthine.

These structures reflect blue light.

Therefore, even the blue color seen by frogs is not a pigment.

As a result of the interaction of the outside light with these microscopic structures in the frog's skin, it shows us blue, which means that there are no blue frogs in this world, only frogs that can see blue.

Now you know too.

Now let's see why the sky is blue. When the sun reaches the earth's atmosphere, it collides with all the gases and particles in the air and the light scatters in all directions.

Because blue light travels in short waves, it spreads over a larger range than other colors.

This is why we often see a blue sky.

Why is the sea blue? So a very simple thing is that the ocean appears blue because this network absorbs the colors of the red part of the light spectrum, as a result of which we can see a blue sea.

There is nothing blue.

It's okay to lie in life.

You know that too.

So, no matter how rare blue is, the world's favorite color is blue because it is mild.

And because of its rarity, people like it very much.

So my favorite colors are black and blue.

The rarity of blue in nature is a fascinating process that highlights the complex interactions between biology, chemistry and physics.

So it reminds us of the complexity and wonder of the natural world.
