Viper — a very youthful appearance , which began to take shape after the end of the last glacial period (ie, that snake evolution is much younger than we , the people). Therefore color viper is highly variable: the nature seemed to have not decided how it will look its creation. The common property of color can only be considered that by some background stretches along the back bar , which usually has the form of a zigzag , but it happens and with smooth edges . Typically , the strip darker than the background , but there are exceptions. But the background is! Here nature is enough to amuse with the search for the desired color scheme . Gray back snakes can be any brightness and tonality of colors as well as blue , purple or blue , yellow, green , orange, pink and red , and all shades of brown and brown colors. In short , virtually the entire palette . The only pattern that I have noticed: males usually disguise themselves in a gray , purple or blue- blue clothes, and females flaunted greenish , yellow , brownish or reddish attire. Furthermore, both males and females can be pure black. However, the males in this case , there are usually tiny white specks on the upper lips and bottom of the tail painted white or pale yellow. And the females are red, pink and white spots on the lips and throat , and the tail from the bottom of juicy yolk color . Sometimes there are vipers , who instead of zig-zag on the back allow the elongated strips across the body . There are instances in black with a bright orange zigzag. I came across at all inconceivable viper: they have one side of the body along the axis of the spine, for example the left — blue with spots and half zigzag , and right — without a black pattern. Zmeelovy these are called " burnt " . A motley and varied colored animal and I do not remember. As soon as the birds , such as ruffs , can boast such a variety of colors. It is interesting to note that all of the n- dyuchata are born of the same brown- brown color with a dark brown zigzag pattern on the back. The color change begins in about a year , after five to seven molts . ______________________________________________________________________ Это рассказ о Гадюке Обыкновенной
