Geographic range
The Bamboo Pit Viper is a widespread species throughout the peninsular India. It is also found albeit very scarcely in the eastern region of India spanning from Odisha, Jharkhand, and West Bengal.
The type locality is "Vizagapatam, India", which is based on Russell (1796).
Habitat
Despite its name, the species is not particularly associated to Bamboo thickets. It is an arboreal snake, usually found on low to medium high bushes and trees, and often near streams. Being a nocturnal creature, it is found at lower heights as it sits in ambush at night. During daytime, these snakes ascend at greater heights.
Behaviour
C. gramineus is arboreal and nocturnal. When threatened, it is aggressive and does not hesitate to bite. The venom is hemotoxic and neurotoxic.
Diet
It feeds on lizards, rats, and birds.
Reproduction
C. gramineus is ovoviviparous. Adult females give birth to 6 to 11 young, which measure up to 4.5 in (110 mm) in length.
