Regional assemblages of species of poisonous snakes in different geographical areas may vary depending on your location. In each location the major efforts must be made to be aware of the presence of toxic species, as they are not the dominant species and represent a danger to humans. In addition, they are much better known under local names or simplified compared to the more common and comparatively less dangerous individuals.

Thanks to its incredible sensitivity, this hole helps to locate and attack warm-blooded animals (of course, when the predator is close enough to potenitally victims). It is considered, among other things, that such amharinya bodies along the lower jaw perform the same functions and have common Boas (or devouring snakes).
