In mice, the intravenous LD50 is 1.1 mg/kg. Relatively little is known about the toxicity and composition of the venom. The fangs penetrate deep into the victim and the venom flows through the hollow fangs into the wound.īecause of its restricted geographic range, few bites have been reported. When a rhino viper opens its mouth, it does not necessarily mean that the fangs will flip down into place. The snake has the ability to control the movement of its fangs. When not in use, the rhino viper's fangs are folded up into the roof of the snake's mouth. This venom attacks the circulatory system of the snake's victim, destroying tissue and blood vessels. The hemotoxic venom in rhinoceros vipers is much more dominant. Bitis nasicornis has both neurotoxic, as well as hemotoxic venom, as do most other venomous snakes. This is unlike the Gaboon viper, the largest of the vipers, which uses a considerably larger amount of venom. Small doses of the snake's primarily hemotoxic venom can be deadly.

Butterfly vipers prefer to hunt by ambush, and probably spend much of their life motionless, waiting for prey to wander by. They are sometimes found in shallow pools and have been described as powerful swimmers. This climbing behavior is aided by a partially prehensile tail. Although mainly terrestrial, they are also known to climb into trees and thickets, where they have been found up to 3 m (9.8 ft) above the ground. Their vivid coloration actually gives them excellent camouflage in the dappled light conditions of the forest floor, making them almost invisible.
