what do snakes eat – they are not "vegetarian". All of them are - predators and feed on various species of animals.
Snakes have very strong digestive juices, perform a vital function as a snake swallows its food whole. They have no teeth to tear prey, as do, for example, representatives of the cat family. In birds and turtles, have beaks. And all that is at the snake - it's as thin as a needle, the teeth with which they catch their prey and send in your mouth. But they cannot chew it.

The most unusual for snakes - this is the structure of their jaws, which is associated with a unique way to power. Jaws very loosely attached to the rest of the skull. Jaw teeth are located, and most snakes even in heaven there are two rows of teeth. All of these series of teeth sitting on the bones, driven by special muscles.

Snake eats, pulling one jaw on the extraction, while the other jaw teeth hold it to not burst. Then release the snake teeth, promotes another jaw forward and then plunges them. Thus, the food is pushed into the throat snake.

Thanks to this structure is able to swallow a snake jaw to surprise a large animal. For example, a python eating large animals such as deer and leopard! Of course, smaller snakes eat smaller animals. Most of the feeds on medium sized creatures: frogs, mice, rats, birds and grasshoppers. Some small blind snakes eat termites. And there are those who eat other snakes!

Snakes are very selective in choosing their food. North American green snake, for example, eats spiders, fish, birds and caterpillars, but lizards and mice, it eats. Water snakes eat fish and frogs, and insects and mice, do not touch. Inhabiting North America, the yellow-striped snake an omnivore. Its diet includes worms, fish, frogs, rodents and birds.

Watching the movement of snakes, you first wonder two things. Firstly, as it moves: foot is not seen nothing pushes and pulls the body of a snake - and yet it moves! Well, secondly, the body of the snake "flows" on the ground as if it were no dice!

Nevertheless, the snake simply filled with bones, it is a fact! Snakes have articulated vertebrae to which ribs are attached. Some snakes to their flexible backbone can be attached to 145 pairs of ribs. Vertebrae attached to each other sort of swivel, and attached to each vertebra have its own pair of edges, which gives the vertebrae and ribs freedom of movement.

The tips of each pair of edges, in turn, are connected with the muscles of one of the plates (flakes) on the belly of a snake.

There is a snake bones in the head and jaws. While eating a snake is able to widely push their jaws because the bone cavity and throat are not rigidly fixed. In fact, most snakes swallow the prey, not even, her slaying. They simply digest it alive.

So, as you can see, snakes have bones, though in the form of their slippery body seems absolutely devoid of any solid foundation.
