The snakes and the rattlesnake: a poisonous species


Cascabel snakes belong to the family of the vipers, specifically to the genre Crotalus. They are endemic animals of the American continent, and their populations are distributed from Canada to northern Argentina. The most characteristic of rattlesnakes is their tail, for which they receive their name. There are more than 20 recognized rattle species and they are the most poisonous snakes in North America.


Differences between vipers and snakes

As we have said, the Cascabel snakes belong to the VIPORAS FAMILY. The vipers are normally poisonous, although not all are considered dangerous, and the snakes generally are not, or at least they cannot inoculate a poison that comes to produce serious damage. To differentiate a snake viper we look mainly on its snout and scales. The vipers usually have the fiery and smaller scales, and a pointed snout. 

The snakes are usually larger, they have the largest body scales, they can be fair or not and have no snout. All this are generalities, because each species can have their own peculiarities, so as a precaution, if we find a snake and suspect that it can be poisonous, it is best to get away. They are usually more afraid of us, than us from them.

Cróalo or rattlesnake

These snakes are recognized meters away by the sound of your rattlesnake. The crótalo or rattlesnot is a structure of bone discs that collide with each other with the movement and make a characteristic rattles sound.  The age of one of these snakes can be calculated by the appearance of your rattlesnake, which appears as they grow;Youth specimens may not present it.

Case snakes can exceed two meters and reach four kilos of weight. They are not very large snakes, but their poison can be deadly, although they do not attack by themselves, only when they feel in real danger. The noise they make with their tail is a warning signal when they feel threatened to deter their opponent. Of course, each species can be more or less excitable by itself, for this reason caution is recommended before one of these snakes.

Most of them prefer desert climates and are rarely found in humid soils. They can also be found in abandoned termiters, cereal plantations, coffee or near farms, especially in the barns where cereal is stored, due to the presence of rats that serve as food. This is where the danger of being bite easily by a rattle snake.

Some species inhabit humid jungle areas and others only go out at night. They are also good swimmers and can bite into the water. In general, they are not arborícola species and are found on the ground, although there are exceptions between species and, if there is abundant rain, they are able to climb looking for drier areas.

In areas where it is common to find rattlesnakes, the use of long pants and closed shoes is recommended, in addition to being vigilant on the ground and always having the closest medical center or an antidote by hand located. The bite of the rattlesnakes is very feared for its poison, and they use it to paralyze and reduce large dams. Its poison is highly toxic: it can cause paralysis, internal hemorrhages due to destruction of veins and capillary, necrosis and cardiac arrest membranes.


Bites must be treated as quickly as possible, there is an antidote that reverts the effect of the poison and must be applied immediately. However, the antidote does not cure the effects that poison could have caused, neutralizes its action, prevents mortality, but does not cure possible injuries such as necrosis. Injection of small doses of poison induces the production of antibodies, but once the doses are finished, the antibody level decays to zero. If you travel to a country where these snakes abound, you must inform yourself about how to avoid them and how to act in a bite.
