because they are frightened and dont know where they are or what there doing almost like humans
An initial strike catches the prey, a Python has 4 rows of teeth (two each side) on its upper jaw and 2 rows on the bottom. The strike is fairly quick, close to that of a blink, and if the snake hits its target just as quick as the strike the snake will coil itself around its prey and begins constriction. When striking defensively a snake will strike and release but when hunting a Ball Python will strike and hold until the constriction process has killed the prey. Contrary to movies, constriction doesn't break bones, as the prey exhales air the snake will squeeze tighter preventing the prey from inhaling, usually resulting in shock and eventual suffocation. The snake waits for the heartbeat to stop before consuming, in rare cases a snake won't coil the prey completely but using just part of its body applying force tot he prey against a tree or rock or even the ground to achieve the same effect.
