These snakes have poisonous teeth sitting on the posterior end of the maxillary bone and have a groove to drain the poison. They are almost safe and “mildly” poisonous, but among them there are two BIG exceptions:
1) Bumplang (Dispholidus typus)
2) Gray wood or Wine snake
From the bites of these two snakes, people died. Other well-known examples of rear-rowed snakes are: Boiga (Boiga), Herpetons (Herpeton spp.).
These snakes have tubular teeth sitting at the anterior end of the maxillary bone, greatly enlarged and most often have an internal canal. The snake’s tusk, when bitten, acts like a syringe. The reservoir with the poison, located at its base, is compressed, pushing the poison into the body of the victim.
Obvious examples of snakes are of the type: Cobra (Naja), Mamba (Dendroaspis), Coral aspids (Mucrurus), etc. Among these snakes, there are several that are considered one of the most poisonous in the world.
These snakes have long and tubular, movable teeth fixed on a very short maxillary bone, which is able to rotate. In this case, the cannabis fangs, with the mouth closed, lie along the jaw, with the point back, when the mouth opens, they become perpendicular, taking the “combat” position. This makes these snakes the most dangerous in the work. They can open their mouth almost 180% and hit almost any part of your body.
