How to recognize a venomous snake

Statistically, in the world there are about 4 thousand species of snakes, about 10% from them are poisonous. Every year in the world about 40 thousand people perish from stings of venomous snakes. The high rate of mortality from meetings with these creations is registered in Brazil and in India. In the USA about 15 people in a year perish from stings of such snakes. Isolated cases of death of people from venomous snakes are recorded in Europe.


1. First of all, it should be noted that the sting of a venomous snake not always leads to organism poisoning with poison. For example, vipers do not emit the poison practically in 25% of cases of stings, and cobras – approximately in 50% of cases. But if snake poison, nevertheless, was injected into blood of the person, then it can make at once harmful effects, indirectly or directly influencing all systems of his vitals. Attention! Not always snake poison can constitute danger to the person! Some types of poison do not affect the person at all, and some will lead to a lethal outcome within several seconds.

2. There are several ways by definition of a venomous snake, however entirely it is impossible to rely on them at all! If the sting of a snake took place to be, then it is necessary to take urgently all necessary measures for first aid. So, it is possible to distinguish a venomous snake on the following signs.

3. First, the majority of venomous snakes have bright coloring of the body. As a rule, harmless dragons are painted in the same colors and can have one or several longitudinal strips from the head to a tail. Poisonous dragons can have various patterns in the form of rhombuses, spots, cross tiger strips, some drawings (for example, "points" on a hood at a cobra). Some venomous snakes on a body have bright specks, circles, color blocks of irregular shapes. Also two-color venomous snakes meet: the first half of their trunk is painted in one color, and the second – in another.

4. Secondly, there is an opinion that the venomous snake can be distinguished from her head, nonpoisonous in a form. Allegedly at the first it has the kopyeobrazny form, and at the second – more round. However this rule is not always confirmed. Some zoologists claim that not always the heads of venomous snakes have the spear-shaped or trihedral head. Therefore it is dangerous to rely only on this sign! However, statistically, at many (but not at all) venomous snakes of the head, really, have the form of a spear (triangle).

5. Thirdly, venomous snakes between eyes and nostrils have a small dimple – a peculiar deepening. These are heatsensitive channels. There is an opinion that pupils at nonpoisonous snakes have rounded shape, and at poisonous – elliptic. It, of course, is true, but not fully. For example, at cobras and bumslang pupils too round, however these snakes – some of the most poisonous in the world.

6. In conclusion It should be noted that there is no uniform characteristic sign which would distinguish venomous snakes from nonpoisonous just! The exception can make only presence or absence at them of poisonous crescent teeth and glands. But all difficulty is that these bodies cannot be found in a live snake without potential risk for the life. In this regard the only reliable way of recognition of venomous snakes is familiarity with venomous and nonpoisonous snakes of the region by means of scientific literature, medical sources, the Internet.
