Like a chameleon changes color, and what does it depend?

Chameleon - inhabitant of sultry Africa, acquired fame thanks to the unique ability to change color of the skin.This little lizard length of only 30 cm can be transformed, becoming black, pink, green, blue, red, yellow.Many scientists have conducted various studies to find out how a chameleon changes color, and what it involves.It was assumed that he had thus disguised as the surrounding background.But this assumption was wrong.

This lizard itself is unique.She looks like a dragon, often changes the color of the skin for hours sitting on the branches of trees waiting for the victim, which captures the long tongue.Her eyes live separate lives, turning in different directions.The chameleon changes color due to special cells - chromatophores.His skin is transparent, so it is clearly visible cells containing different pigment colors.

a long time, researchers could not understand how a chameleon changes color, and why this is happening.It was assumed that he needed it for masking.After all, color, such as green lizard can be masked by the foliage, hiding from predators and waiting for their victims.Indeed, in the course of evolution, many chameleons have learned to acquire the color and pattern of their enemy - such as a bird or a snake.

Modern research has shown that the process of how a chameleon changes color, is entirely dependent on its condition.The color of the skin varies from mood swings - reactions such as fear or joy.It may even depend on the temperature.In Africa, many chameleons become black in the morning to attract the sun's rays, but brighten the day, that was not so hot.Variegated colors they use in courtship in order to attract members of the opposite stati.

Chromatophores chameleons are located in the deeper layers of skin and are directly dependent on the nervous system.The upper layer contains the red and yellow-containing pigment cells.Next located crystalline substance guanine, which accurately reproduces the color blue.Beneath - melanophores, the pigments responsible for the colors of black and yellow and containing melanin.That is located in the cell pellets pigment completely affects the color.Chameleon - a very interesting animal.After all the pigments in its cells very rapidly moving, changing color.If they are concentrated in the center of the cell, it will be transparent, if uniformly distributed on it, the color in color intensity.

nerve endings connected with brain chromatophores, whence come the team to change.The way a chameleon changes color, you can compare with a palette in which the paint, mixing, creating a completely new shades.Due to its ability to change the color of the skin, this lizard has gained immense popularity.Today, fabrics, paints, and other things, shimmering in different shades or alter them, called Chameleon.

Although it seems that changing color lizard wants to disguise, it is not.She did not pay attention to the background.On skin color affects mood, emotion experienced by the air temperature, but not the surroundings.Therefore, the view that when the chameleon would be on the board, then it will appear black and white cells, is fundamentally wrong.
