The rattlesnakes are part of the Crotalinae family, the genera Crotalus and Sistrurus. It is also known as horridus crotalus. It is a venomous species found in the United States (southern Minnesota, south of New Hampshire, southern Texas and northern Florida).
It is inexplicably absent in Louisiana. It is the most popular species in the northeastern US, was highlighted in the American Revolution and was the first continental symbol of the navy. There are no currently known subspecies. It is generally found in deciduous forests with rough terrain.
In summer, females prefer open rocky areas for higher temperatures, while males prefer to stay in cooler but denser wooded forests. In winter, they often hibernate in caves with other snakes.
The main prey of rattlesnakes are small mammals, but they also eat birds, frogs, other smaller snakes and others. Like most snakes, the upper and lower jaws have elastic ligaments that allow them to swallow a larger prey than their head.
In captivity the prey is related to the circumference of their body. Usually they eat 1-2 animals a week. The time until the digestion is complete varies depending on the size of the animal, the temperature of the environment and the acids produced by the stomach.
The rattlesnake is a popular food in South and East American kitchens, sometimes sold in meat shops. The taste of meat is compared to that of chicken, frog, turtle, fish, rabbit.
Adults usually grow in lengths between 90 – 150cm. The maximum length was about 2m. The distinct marks on the body (also called spots or circles, depending on the shape) are “arranged” in 21-26 rows (usually 26 in the north and 23 in the south).
Males have 20-30 caudal scales, while females are only 15-26.
The rattlesnake is one of the most dangerous species in North America because of its long teeth and the amount of venom it injects.
Often it prevents prey when it enters the offensive or the defensive, moving the tail. The specific sound derived from it gives it the name of the snake.
An individual Cyst wrote in 1845 that he lived in western Pennsylvania for many years and all this time he only heard of a single death caused by the bite of these beautiful animals. Four types of venom have been described as belonging to this species: A non-toxic, B haemorrhagic and proteolytic, A + B and C which is relatively weak.
Many species of snakes are raised in captivity for harvesting their venom. The most effective method of antivenin is the result of mixing or chemical processes (I do not know exactly the process by which the antivenin is produced). When they hunt, they inject all the venom in the prey, but in defense cases they can inject less venom or not at all when they bite.
A scared or injured snake cannot control the amount of venom and in case of bite it injects all the venom present in the corners at that moment. People in the health field cataloged on a scale from 0 to 5 the degree of danger in case of a rattlesnake bite, the 5th degree being the most dangerous.
In stages 4 or 5 there may be swelling and tingling in the area of the bite, tingling, dizziness, bleeding, vomiting, shock, etc. There may also be difficulty breathing, paralysis, etc. Most medical professionals recommend keeping calm in order to avoid accelerating the circulation of venom through the body.
The bells are actually beads located towards the top of the tail which, by the movement, continue to produce that specific sound. At each glow, a new tail segment appears.
They can appear several times a year, especially when they are young, so growing. Newborn snakes will not be able to use their bells until after the first mating. Adults may lose their bells in various situations, in battles with other snakes or with predators, but at the next mating there is still a segment with bells.
It seems that nature belongs to these reptiles. However, in wet weather, the skin absorbs water and the bells are not heard.
Many breeds of snakes give birth to baby snakes through eggs.
Rattlesnakes keep eggs in their bodies and when hatching they give birth to live snakes.
Snakes can “go” from birth, they are independent.
