The tropical climate with evergreen, semi-evergreen and moist deciduous forest in Periyar creates a perfect environment for snakes. The Indian Python is seen in dense as well as in open forest. Pythons are slow moving snakes, appearing timid and rarely rousing seriously to escape even when attacked. Pythons also have a peculiar method of movement, the body moving in a straight line like a millipede.

These snakes feeds on mammals, birds and reptiles rousing to activity when hunting.
