There is a legend that God deprived of a mole of sight because that constantly rummaged in the earth and spoiled trees in a paradise garden. God promised to return sight to a mole when that digs so many holes, how many stars in the sky...
To understand what animals are, it is possible to make a small experiment. To take out a mole from a mink and to put on the Earth's surface. You will see that he immediately will begin to move here and there in search of the friable soil that quicker to it to bury. The mole is capable to be earthed approximately in one minute. Since underground kingdom is its favourite territory of dwelling.
It is obvious that the mole who is constantly underground not especially and needs sight. Necessary for existence he finds all underground, including livelihood. He, generally eats insects and worms. In search of livelihood he is constantly because more, than 12 hours, without food it is not capable to sustain. All his body is just adapted for such way of life. Even wool at these animals has "a chernozem shade" and grows in a special way - directly that very conveniently for movement underground in any direction. The mole nevertheless has eyes, the truth the size they about a pin head. They are densely closed by eyelids and wool which protect eyes from hit of the earth in them. The mole practically does not use sight, but, nevertheless, distinguishes light and darkness. This ability often helps it in case of danger. If he notices "gleam", then at once tries to bury more deeply not to appear on a surface at all. The mole winters in a top soil which does not freeze through up to the end and where it is always possible to find some livelihood. It is impossible to call moles absolutely blind. They very much developed touch and sense of smell. It is possible to tell that wide paliform paws, strong claws and a sharp scent just and are the true sight of moles. This "sight" helps it to survive underground, in the conditions of total absence of light. Eyes at some of these animals can grow with thin transparent skin completely.
