It like water body and wet surrounding during dry and warm weather.
Feeds on rodents, all small & medium size mammals, birds, monitors and other lizards, etc. Famous for its deadly suffocative constriction power.
Rock Python is generally a silent species and likes to escape on provocation. On further disturbance it coils its body and produce hissing sound (which is less louder than Russel’s Viper) and attacks on its enemy from one third front body. Pythons can hibernate during winter from December to February in groups.

Rescue Situations
Rock Python is one of the biggest snake in rescue issues. In rescues they are found in size range from juveniles to adults upto 14ft. They always try to keep safe distance from humans and rarely enter in houses. In few cases Pythons act as domestic bird or meat eaters also. Mostly observed while crossing roads, in agricultural lands, gardens, farms, around poultry farms etc. In most of the cases their “catching” is not required if rescuer uses his own logic and experience by observing the situation. People call rescuers when they find a huge snake even in forest or place far from colonies. In such condition, rescuer must not disturb the animal and let it go in its territory again. If required, they can release them within 500mtr range from rescue point in the same geographical section.
