The rattlesnake and its poisonous bite


Veneous snakes: around the world there are many snakes whose poisonous bite can be fatal to humans. In the United States, however, there are only four: the coral snake, copper head, cotton mouth water moccasin and rattlesnake. Description and identification of the rattlesnake: there are 32 known species, which contain numerous subspecies with many color variations. Everyone shares in a distinctively triangular head and rattles articulated in the tail.

Case snakes, copper heads and cotton mouths are all vipers. The pit vipers are snakes with two graves under their nose to detect heat, which allows them to hunt hot blood dams. The holes are so sensitive that the snake can determine the size of the hot blood animal and can even detect dams in complete darkness.


Each species can be identified by variations in color patterns in their skin. The colors range from tones of brown, gray and black, to tones of yellow, cream, oxide, olive and light pink. The skin of a rattlesnake can show a pattern with bands, in the form of a diamond or with spots, although some species of rattlesnakes do not have any identification pattern.

Case snakes have a fork that move up and down. The tongue collects particles and microscopic gases of the air. When the tongue gets again in the mouth, it touches a sensitive point in the palate called vomeronasal organ or organ of Jacobson. This organ collects the particles collected by the tongue and sends messages to the brain of the snake identifying the smell as food, enemy, partner or other object or substance.

Case snakes have external nostrils covered with olfactory cells that also capture the smell, although they are mainly used to breathe. The tongue fork is navigation aid. You can provide information based on which side or fork of the tongue has the strongest presence of a particular smell. This information can help the rattlesnake to follow its prey or find the way home.

Case snakes capture vibrations through the muscles of their body that send the sound to the bones of the jaw and to the organs of the inner ear. Case snakes have no external ears and, therefore, depend on these vibrations to capture the sound. The snake’s eyes can detect objects or movements about 40 feet away, but their vision is much more clear when objects are closer. The pupils of a rattlesnake are elliptical, not round, which allows you to see well with little light. This is useful for night hunting.

In ideal habitats where there is an abundant and constant supply of small rodents, the rattlesnake sometimes reaches a length of five feet, but the average size of an adult is three to four feet.

Case snake range: Although most rattlesnakes are concentrated in the southwest of the United States, they extend north, east and south in amounts and decreasing varieties. Each contiguous state has one or more rattlesnake varieties. The rattlesnake is found in many different biomes, ranging from along the coast to the sea level, to interior grasslands and desert areas, and even mountains at elevations of more than 10,000 feet.

Beat’s behavior: In the northern areas of its distribution area, and in the highest elevations, the bell snakes congregate in the fall in the cracks of the rocky shelves to hibernate during the winter. They return to these places annually. These places are known as snakes.

When temperatures begin to warm up in April, rattlesnakes leave hibernation. They remain close to the entrance of the den for a few days, sunbathing, and then address their summer habitats. Most snakes are reserved in their summer activities, hunt at night and remain inactive and out of view for days during the digestive period, after eating a squirrel or a small rabbit. Consequently, more snakes are seen in spring and autumn migrations to and from their winter homes.

Case snakes are ectodermal cold blood and depend on external sources to regulate their body temperature. When rattlesnakes are too hot, they retire in the shade or in a burrow. When a rattlesnake is too cold, they themselves take the sun or find a surface, such as a paved road, to absorb the heat of the asphalt. It is common to find snakes on the road in the afternoon when they try to heat their bodies falling in paved asphalt or concrete areas.

Case snake life cycle: while some types of snakes put eggs, the young of a rattle snake are born alive. The rattlesnake has eggs, but the eggs are carried inside the body of the female. Once the eggs are fertilized, they are transported for approximately 90 days. The eggs hatch inside the body of the rattus and then gives birth to their young. A reproductive system of this type is called ovoviviparo.

Case snakes reach sexual maturity around three years of age. The mating usually occurs in spring after leaving hibernation, but can also occur in autumn. During the mating process, the female rattlesnake is passive while the male craws over it. Making sudden movements with the back of his body, the male presses his tail under the female’s tail to inseminate it. 

The male moves the tongue continuously during the mating process, which can continue for several hours or more. Females can store semen for months, allowing them to fertilize ovules sometimes six months later. The rattles female can take four to 25 eggs, of which an average of nine or ten young are born alive. A female rattle snake usually reproduces every two or three years. The young are usually born between August and October.

The newborn rattle snake measures about ten inches long and has a small corneo button at the tip of the tail. Babies rattle have poison, short fangs and are dangerous from birth. In fact, they are more bellicose than adults. Although they cannot make a swallowing sound, young people throw themselves into a defensive pose and hit repeatedly when they are bother.

The young rattle is completely independent of the mother. They remain in the area of their birth during the first seven to ten days, until they move their first baby skin and add their first rattle. The garbage will begin to disperse as they venture in search of food. Many newborn rattlesnakes do not survive their first year, either starving or being devoured by birds and animals. Even if they survive the first summer, they can die during the first winter, if they cannot find an appropriate warm crack for hibernar.


Beat snakes are carnivorous. Instead of chewing the food, I swallow it whole. The size of the dam that selects a rattlesnake is limited by its own ability to eat it, based on its own size. Case snakes eat lizards and small rodents such as Earth squirrels, small rabbits, rats and mice, hitting instead of trying to hold their prey.

The rattling snake first bites its prey to immobilize it with a toxic poison. When the hollow fangs of the rattles. Most small dams are immediately stunned. The poison stuns and immobilizes the dam, giving time for the rattles to swallow the entire victim. The poison also begins the digestive process as the dam tissue breaks down.

Case snakes have a highly efficient digestive system that consumes a lot of metabolic energy. After a rattlesnake swallows its prey, it usually hides while the food is digested. Beat snakes become slow while digesting, a process that can take several days depending on the size of the food.


If everything goes well, young people grow up quickly. Every time they leave hibernation, they move from leather. With each skin detachment (mute) a new rattle appears. During the rapid growth of the first years, they can move three times a year. Therefore, the number of bells is not a true indicator of age. Gases are also wearing or broken, so it is unusual to find an adult snake with more than 8 or 10 bells.

The average life of a rattlesnake is 20 to 30 years in captivity. In nature, life expectancy is lower due to predation, illness or accident by accident. The king snake is well known for being immune to the poison of many vipers, including rattlesnakes. Case snakes are part of the real snake diet. Roadrunches, pigs, hawks, eagles and humans are also rattling snake predators.
