Poisonous snakes are among the most feared creatures in the animal world. The toxic secretion of poisonous snakes is so deadly that it can induce paralysis and death in no more than thirty minutes, not to mention the chances of losing eye sight if venom gets into your eyes. Although the risk of bites remains high when you accidentally come across them, poisonous snakes prove in fact harmless as they rely on their venom to survive: no snake will bite unless in defense or to hunt its meal . The rest of the negative feelings towards snakes comes from a faulty perception triggered by ancient myths.
The structure of the venom secreted by poisonous snakes is very complex: there is mainly a combination of proteins and toxins that when spread in the prey's body paralyze and eventually kill it. The toxin weakens the heart, the lungs and the muscles first, and depending on this action mode scientists have classified poisonous snakes into species that destroy blood vessels and cause unstoppable hemorrhage, venomous species that paralyze the heart and, last but not least, others that only cause terrible muscle pain. The poisonous snakes with the most frightening of reputations are corals closely followed by cobras.
The intricacies of snake venom still make the subject of comprehensive scientific studies. The only cure for poisonous snakes bites is the immediate administration of antivenins. There are however some factors that increase or decrease the victim's chances of staying alive: thus, knowing the type of snake that caused the bite and its exact location prove crucial. If too much time lapses between the moment of the bite and the administration of the antivenin, serious health damage or even death could occur. Furthermore, there have been cases of patients who developed instant allergies to poisonous snake bites or to antidotes and died.
Rattlesnakes cause most of the bites in the United States, yet death from such accidents is a rarity in our times since medical help is not a problem anymore. The water moccasin, the copperhead and the cottonmouth belong to the same poisonous family as the rattlesnake; they are highly poisonous snakes which you should avoid by all means possible. Stressful incidents involving snake attacks are often behind snake phobia or this excessive fear can have roots in sociological ancestral beliefs that are manifest even with people who have never come across a snake in their life.
