The Python is one of the nonpoisonous serpents pertaining to the family of the Boidos. Pitones is great and muscular and kills to their victim by strangling or constriction. Although most of pitones they are fed on small mammals, some of the greatest species can devour pigs small and goats; rare time they have killed a human being. Pitones measures between 1 and 10 meters in length and weighs up to 140 kilograms.

They are primitive serpents that, like the boas, show vestiges of their predecessors, the lizards, as they are two tiny back extremities, present only in the male. The female puts between 15 and 100 eggs, whose size varies with the species, and incubate them until they are opened. Pitones lives sometimes near the water, where they are hidden between the foliage, or they are hung of the branches of the trees. 

They exist between 20 and 25 species of Pythons that live in tropical and subtropical regions on Africa, Asia, Australia and the islands of the Pacific. Pitón reticulada of the Southeastern of Asia is between the serpents greater than they are known; it reaches a length of 10 M.s 

Others pythons known well are pitón tigrina, of 7.5 ms of length, the favorite of the manipulators of serpents; pitón of Seba, 6.5 ms of length, and pitón real of the equatorial Africa, that measures 1.5 ms and enrosca on itself forming a ball that is possible to make roll on the ground.
