The Russell's Viper is Terrestrial (lives on the ground) and is usually nocturnal, but in cool weathers it is diurnal. When threaten it raises its head and makes a hissing noise which is said to be louder than other snakes. Their bite may sometimes be a simple snap, or sometimes the jaws hang on to the enemy for a few seconds. Adults are said to be slow and sluggish but when disturbed they become aggressive. Since of its aggressiveness and venom many animals and people are scared of this snake. That is why another snake, Rough-scaled Sand Boa, mimics the color pattern of the Russell's Viper so it looks like the Russell's Viper, but it is actually harmless. Adult's venom glands hold around 21–268 mg of venom, while young one's venom glands hold around 8–79 mg of venom.
