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. In Panama, the special distribution received three main families of poisonous snakes, namely: alkoholowe vipers, coral snakes and sea snakes.
Only in the Western hemisphere of the Earth all the vipers are so-called pits, which represent a deepening from the outer side of the upper jaw, between the nose hole and eye, which indicates zoologist Harold Trapido, is sensitive to changes in the ambient temperature of the body. 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). Even assuming that such a snake is removed and the language she blinded with blackened collodion, it will still be able to produce its fatal bite, aiming for an electric bulb, covered with black material, provided, of course, that this cover is hot from the lamp.
The vipers have retractable, long, curved and hollow fangs located at the front of the upper jaw. These fangs can move forward and backward when wypracowanie poison. Sting when the fangs hit the victim with poison, there is a small shift of Fang ago, which, in turn, causes a contraction of the venom gland, and venom pours through the hole in the Fang. The fangs of these snakes can reach lengths of up to three centimeters large species of fer-de-lance or bushmaster.
To accurately identify a poisonous snake and the level of danger it poses to you, you need a careful study of all species and subspecies characteristics of individual varieties. Often there are differences between young individuals from adults. There is hardly any more or less well-defined practical method, which can accurately set the differences between different snake species. There were only individual facts that only professionals can show their competence and not to make a mistake because of areal differences. Thus, for example, to distinguish snakes in Central America it is especially important to consider the particular location of the pits, while many vipers on the other continents, these holes not. Another fact, namely, that the pupil in the form of longitudinal stripes more typical of the harmless snakes, are valid only for individuals with nocturnal lifestyles.
In Panama alkoholowe Viper presents seven major species, including the fer-de-lance, bushmaster, tree snake, tropical gremuchiy and some others. And among them, oddly enough, there are significant differences, which can easily introduce the layperson astray. For example, bushmasters there is a double row of scales on the tail, though other species of poisonous snakes have only one row. Snakes of all kinds after molting also differ from snakes of the same species with the old skin, the shedding of which has not yet passed.
The poison, incidentally, is a potent saliva produced by the parotid gland, which in humans is the salivary gland that increases when mumps. The use of venom as a protective measure of only secondary importance, while his main objective is hunting and killing victims. That is why most of the snake’s venom is spent on the bite victims.
However, statistics show that the chances to die from poisonous snake bites in Panama is not higher than dying from a lightning strike, and in the whole Central America, the mortality due to snake bites does not exceed 10. This surprisingly low level of deaths for this reason the tropics is because the snakes are fed, and they need not hibernate. Apparently, these two reasons were also affected by the decrease in the influence of their poison on the human body.
