Origin
The rattlesnake is part of the family Crotalinae, genera Crotalus and Sistrurus. It is also known as horridus crotalus. It is a venomous species found in the United States (southern Minnesota, southern New Hampshire, southern Texas and northern Florida).
Inexplicably it is 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 Woodland. In winter they hibernate in caves often with other snakes.
Feeding rattlesnake
The main prey of rattlesnakes are small mammals, but they also eat birds, frogs, other smaller snakes and others. Like most snakes, they have upper and lower jaws and have elastic ligaments that allow them to swallow prey larger than their heads.
In captivity the prey is pegged to their body circumference. They usually eat 1-2 animals a week. The time until digestion is complete varies depending on the size of the animal, the temperature of the environment and the acids produced by the stomach.
Rattlesnake is a popular food in southern and Eastern American cuisines, sometimes sold in meat shops. The taste of meat is compared to that of chicken, frog, turtle, fish, rabbit, etc.
Features rattlesnake
Adults usually grow to lengths between 90-150cm. The maximum length was almost 2m. the distinctive marks on the body (they are 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 have 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.
It often prevents its prey, when going on the offensive or defensive, by moving its tail. The specific sound made by this gives it the name of the snake.
A Cist individual wrote in 1845 that he had lived in western Pennsylvania for many years and in all that time had heard of only one 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 hemorrhagic and proteolytic, a+b and C which is relatively weak.
Many species of snakes are bred in captivity to harvest their venom. The most effective method of antivenin is the result of mixing or chemical processes(I do not know the exact process by which the antivenin is produced). When hunting they inject all the venom into their prey, but in defense cases they can inject less or no venom when they bite.
A frightened or injured snake cannot control the amount of Venom and in the event of a bite injects all the venom present into its fangs at the time. Health scientists listed the danger of a rattlesnake bite on a scale of 0 to 5, with Grade 5 being the most dangerous.
In stages 4 or 5 there may be swelling and bruising in the bite area, tingling, dizziness, sagging, vomiting, shock, etc.there may also be shortness of breath, Paralysis, etc. most medical professionals recommend keeping calm in order to avoid that the circulation of venom through the body.
Bells are actually beads located towards the tip of the tail that through continuous movement make that specific sound. With each Moult "appears" a new segment at the tail.
They can shed 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 Moult. Adults can lose bells in various situations, in fights with other snakes or predators, but the next molt appears another segment with bells.
It seems that nature cares about these reptiles. However, during wet periods of rain, the skin absorbs water and the bells are not heard.
Rattlesnake breeding
Many breeds of snakes give birth to Cubs through eggs.
Rattlesnakes keep their eggs in their bodies and when they hatch they give birth to live chicks.
Snakes can "walk" from birth, they are independent.
