Brief description of the suborder
To the suborder of snakes are some of the most peculiar creatures: their unusual appearance, the original way of movement, a lot of the cool features of the behavior, the toxicity of many species.
In the structure of the skull of the serpent are the most characteristic and robust features of these animals that distinguish them from lizards. They provide an exceptional elongation of the mouth of snakes that allows them to swallow whole prey, which is much thicker than their bodies. Bones of the facial skull snakes movably interconnected, and the lower jaw is suspended from the skull on highly tensile cords.
The teeth of snakes are well developed and are used for biting, grasping the prey and pushing it into the esophagus, but not for chewing or tearing the prey.
The girdle of the forelimbs are completely absent, and from the waist of the hind limbs in some species there was a small bone rudiments of the pelvis.
The most important sensory organ of snakes is the language in combination with the organ of Jacobson. The eyes also play an important role in the orientation of the snakes. The snakes sense of smell is well developed and serves as one of the guiding feelings. The hearing is weakened. Some snakes have thermal sense organs, or remote thermostats, allowing them to capture the heat coming from the body of the prey.
There are known about 3000 species of snakes, belonging to 16 families and more than 450 genera.
