Habits and Lifestyle

White-lipped pit vipers are generally solitary creatures. They are nocturnal and prefer to avoid high daytime temperatures and to hunt when their favored prey are also active. The snakes' heat-sensitive pits are also thought to help them locate cooler areas in which to rest. As ambush predators, White-lipped pit vipers typically wait patiently somewhere for unsuspecting prey to wander by. They don't strike and release their prey; like many arboreal snakes, they strike and hold on to the prey item until it dies.
