Huge snakes are characterized by the absence of limbs and elongated body. Some have bites poisonous , such as cobras and vipers , which they use to kill their prey before eating. Other huge snakes, such as boas and pythons , kill their prey by constriction . The skin of the huge snake is covered with scales . Most huge snakes use the ventral scales to move, holding them to surfaces. His eyelids are permanently closed, but are actually transparent scales. The huge snakes shed skin regularly. Unlike other reptiles , skin change is made ​​in one piece as if pulled from a mean. This is done as the animal grows and also to repair wounds and get rid of external parasites. The periodic renewal has made ​​the huge snake a symbol of health and medicine.

Locomotion is by undulations of the body side; the enlarged ventral scales of many huge snakes prevent sliding in the opposite direction to the march. Some huge snakes, such as certain boas and vipers can also scroll through muscle movements of the ventral scales with your extended almost straight body. The boas and pythons have rudimentary hind limbs and their waists; huge snakes can be seen in these claws on the outside and on each side of the cloaca that play a role in intercourse . Teeth are solid, prehensile, backward curved to hold the prey and are not intended to inoculate venom. This is the case of many colubrids , boids and pitónidos . huge snakes are generally harmless to humans, with the exception of large constrictors ( pythons , anacondas ).

The respiratory system and viscera are highly modified since the tubular body of the huge snake requires all bodies are elongated and thin. The glottis can be projected forward to keep the airway open during ingestion of prey and, in some species a part of the trachea is specialized in breathing, forming a tracheal lung. The vision is limited details, but does not prevent the detection of movement. Some huge snakes have loreal pits , which can detect the heat. However it does not indicate that they have infrared vision, since the information is going to different areas of the brain vision. Just know if everything is hotter or less. The sense of hearing in huge snakes is very limited as the auditory organs have degenerated; lack the eardrum , the tympanic cavity and the Eustachian tube , and columella articulates with the square . It therefore seems unlikely that huge snakes can clearly hear sounds transmitted by air, but certainly are sensitive to ground vibrations, transmitted through the bones of the jaw .

A huge snake smells through your nose ; the language happens to the air particles Jacobson's organ in the mouth for examination. Most huge snakes reproduce by laying eggs , but some species have developed a different method. The body of the mother retains the eggs until the young are fully trained to live independently. The venom of huge snakes is with specific frequency for their prey, and their role as a defensive mechanism is secondary. Venom, like all salivary secretions, has agents that perform a pre-digestion of food; therefore, even "non-venomous" huge snake can cause damage to tissues .

All huge snakes are carnivorous , feeding on a variety of prey including birds , amphibians , mammals , fish or insects and even reptiles, including other huge snakes in certain species. Generally, huge snakes hunt small to moderate size defenseless prey, which can be quickly and devoured alive. huge snakes can not chew food, and instead swallow them whole. The teeth of a huge snake, which are needle-sharp and angled toward the inside of the mouth, used to retain the dam that will leave your mouth. When swallowing, the maxilla and mandible, which are subject to the skull by ligaments, manage separated to accommodate the size of the prey. Thus, a huge snake can swallow prey that is three times larger than its own head and diameter .

After ingestion , a huge snake must aletargar to fulfill the process of digestion . This is because the digestive process requires a lot of energy to use the huge snake to digest food efficiently, which can last for days or months, depending on the size of the dam. In this state, some organs like the heart and stomach come into greater activity for the whole meal is almost completely digested. The indigestible parts can be excreted or regurgitated.

All huge snakes belong to clade huge snakes, which in turn is a member of the order Squamata . This order also includes the lizards , the huge snakes are related; other members of this order, the blind huge snakes, were also lost legs and superficially resemble huge snakes.
