Rattle snakes

Hi guys,
This is the beginning of the most interesting lecture series about snakes in all over the world! First of all I should tell you why I writing about snakes.. Snakes are my favorite animals because I like their dreadful look! So I have read lot of books & articles about them and also I myself research about them , take their photos and many other things were done as a beginner to collect some knowledge! I must tell you I am not a professional or I am not a scientist but I have some knowledge and now I am going to share it with you! OK! Lets do it!
Today we discuss about Rattle snakes. They are a venomous snakes, can be identified by the end of their tail called rattle.  There are thirty two species of rattle snakes in the world. All of them are predators and have set of fangs to inject their hemotoxic venom to preys.  The preys are mice, rats, little birds and other small animals. Hawks, weasels and king snakes are their predators.
Rattle snakes are native to the America and large number of species (about sixteen) in USA live in Arizona.  Some of other areas are Mexico, Argentina & South America. Usually rattle snakes are live near the open, rocky areas because then they can survive from predators & most of their preys live in those areas. They prefer between 26^oC  to 32^oC but can survive bellow 0^oC. Some rattle snakes hibernate in winter season, gathering together large amount of snakes (some times over 1000) in “rattle snakes dens”.
Generally rattle snakes avoid humans so they rarely bite if we are not provoked them. Most victims are males, young or drunk! You must be careful when negotiate with fallen logs,  boulders & other similar things because it may be cause to rattle snakes attack! Most of rattle snakes have hemotoxic venom & some of them (Mojave rattlesnake) have neurotoxic. Juvenile rattle snakes are dangerous than adults because they can not control the amount of venom injected. 7000 to 8000 people are under attacked per year in America but 5 or 6 people die. If we can take anti-venom treatment within one or two hour of the attack, we have 99% probability of recovery!
