It is precisely unknown when legs disappeared during evolution at ancestors of modern snakes, but on x-rays and now it is possible to see the rudimentary remains of the lower extremities.
Instruction
1. As all dragons are active predators, the lack of legs did not affect their speed and dexterity. Extremities to snakes replace scales which covered a body. Movements for the account of coupling cheshuy with a surface are divided into four main types.
2. Rectilinear movement (caterpillar). Group of scales on the belly party of an animal push a body of a snake forward, plunging into a surface, like boat oars, the others of scales create an emphasis. So one by one scales at first are bulged, then nestle by force of the movement of special group of muscles, and the snake moves ahead.
3. The wavy lateral motion (coiling). The body of a snake as if flows sideways, at the same time there is an alternate reduction of a side body of muscles. All points of a body of an animal contacting to a surface the push, transfer, a support constantly carry out a series of consecutive movements. Due to these movements the picture of rapid and easy movement is created. The number of vertebras at snakes reaches 435, therefore, and number of points of a bend approximately same. The snake is longer, the more powerfully and more promptly she can move.
4. Side course (twisting). The head of a reptile leaves sideways and forward, then to it the body is tightened. At a support on a front part of a trunk, a back part is taken out forward, then the cycle is repeated on the contrary. The feeling is created that the snake goes. Thus moves sandy Eph.
5. Movement by an accordion. The body of a snake is grouped, gathers in "accordion", then the front end is pushed by means of a tail forward. Then the animal tightens a tail.
6. Other ways of movement. Besides the main movements there is a mass of various options at different types of snakes, they depend on a way of life and methods of hunting for the victim. At a lazaniye on trees the spiral twisting around a trunk or a branch is used. Leaning on a tail, the head of a snake is pushed out to a support, having hooked for which the animal tightens a tail part. Snakes are capable to jump, previously having curled up in rings, using force of muscles by the principle of a spring. The paradise snake from Indochina of a hrizopell (false ears) can make the real flights on distances to 35 meters from a palm tree on a palm tree. Air at a breath creates the air chamber serving for planning. Water dragons move, promptly and gracefully swimming in the thickness of water, coiling in the horizontal plane. Speed of movement and stability in water is caused by the shape of a body which is slightly flattened from sides.
7. The various and charming the mysteriousness world of snakes always remains a riddle for the person. Small investigation, maybe, slightly slightly opened a cover of a mystery of prompt predatory reptiles.
