Venom

Rhamnophis aethiopissa is a rear-fanged colubrid, i.e., it has venom, which it may be able to inoculate by biting. Because very little is known about this species and its venom, it is necessary to be very cautious when working with it. This species has an almost identical defence mechanism to the boomslang and twig snakes as it also inflates its throat to make itself look bigger. It is believed that the species of the genus Rhamnophis evolved between the boomslang and the species of the genus Thrasops in terms of their fangs and means of envenomation.
