Product Information

Rattlesnakes are native to the Americas from southern Canada to central Argentina, with the majority of species inhabiting arid regions. [7] The large majority of species live in the American Southwest and Mexico. Four species may be found east of the Mississippi River, and two in South America. In the United States, the state with the most types of rattlesnakes is Arizona, with 13. [8] Most rattlesnake species mate during the summer or fall, while some species mate only in the spring, or during both the spring and fall. [66]

You can throw them in the air, or push them together and the strong magnetic pull will make the eggs clank together and sing. Each oval magnet is 60 x 18 mm. They can be used for a long period of time. Foster, Lynn V.; Mathews, Peter, eds. (2005). "Maya Geography and Mythology". Handbook to life in the ancient Maya world. Oxford University Press. p.91.

Like all pit vipers, rattlesnakes have two organs that can sense radiation; their eyes and a set of heat-sensing "pits" on their faces that enable them to locate prey and move towards it, based on the prey's thermal radiation signature. These pits have a relatively short effective range of about 1ft, but give the rattlesnake a distinct advantage in hunting for warm-blooded creatures at night.

Rattlesnake Common symptoms include swelling, severe pain, tingling, weakness, anxiety, nausea and vomiting, hemorrhaging, perspiration, and (rarely) heart failure. [90] [92] Local pain following envenomation is often intense, increasing with the ensuing edema. [90] Children generally experience more severe symptoms because they receive a larger amount of venom per unit of body mass. [91] Antivenom [ edit ] Rattlesnake fangs are connected by venom ducts to large venom glands near the outer edge of the upper jaw, towards the rear of the head. When the rattlesnake bites, muscles on the sides of the venom glands contract to squeeze the venom through the ducts and into the fangs. When the fangs are not in use, they remain folded against the palate. [37] [38]Whitford, Malachi (2020). "The effects of temperature on the defensive strikes of rattlesnakes" (PDF).

Rattlesnake venom is a mixture of five to fifteen enzymes, various metal ions, biogenic amines, lipids, free amino acids, proteins, and polypeptides. It contains components evolved to immobilize and disable the prey, as well as digestive enzymes, which break down tissue to prepare for later ingestion. [36] [40] The venom is very stable, and retains its toxicity for many years in storage. [36] Cornett, James W. (1998). Rattlesnakes: Answers to Frequent Questions.

Like most other snakes, rattlesnakes aestivate during very hot or dry periods, which is why they are rarely seen during the hottest and driest months of summer.
