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] The venom is hemotoxic, destroying tissue, causing necrosis and coagulopathy (disrupted blood clotting). [41] In the U.S., the tiger rattlesnake ( C. tigris) and some varieties of the Mojave rattlesnake ( C. scutulatus) also have a presynaptic neurotoxic venom component known as Mojave type A toxin, which can cause severe paralysis. [41] [42] [43] Although it has a comparatively low venom yield, [44] the venom toxicity of C. tigris is considered to be among the highest of all rattlesnake venoms, and among the highest of all snakes in the Western Hemisphere based on LD 50 studies conducted on laboratory mice. C. scutulatus is also widely regarded as producing one of the most toxic snake venoms in the Americas, based on LD 50 studies in laboratory mice. [45] The Feathered Serpent of Mesoamerican religion was depicted as having the combined features of the quetzal and rattlesnake. [100] The Ancient Maya considered the rattlesnake to be a "vision serpent" that acted as a conduit to the "otherworld". [101]

Whitefold, 2020 The rattlesnakes movement is bound to its physical makeup and the environment. Environmental temperature can influence the ability of ectotherms to capture prey and/or defend themselves against predators They are a pair of strong magnetic eggs that when tossed together make a loud rattling sound. 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. Rattlesnakes receive their name from the rattle located at the end of their tails, which makes a loud rattling noise when vibrated that deters predators. [2] Rattlesnakes are the leading contributor to snakebite injuries in North America, but rarely bite unless provoked or threatened; if treated promptly, the bites are seldom fatal. In the colder winter months, some rattlesnake species enter a period of brumation, which is dormancy similar to hibernation.Goldfrank, Lewis R., ed. (2006). Goldfrank's toxicologic emergencies (8thed.). McGraw-Hill Professional. p.1657. ISBN 978-0-07-147914-1. Rattlesnakes are preyed upon by hawks, weasels, kingsnakes, and a variety of other species. Rattlesnakes are heavily preyed upon as neonates, while they are still weak and immature. Large numbers of rattlesnakes are killed by humans. Rattlesnake populations in many areas are severely threatened by habitat destruction, poaching, and extermination campaigns. Campbell, Angela L.; Naik, Rajesh R.; Sowards, Laura; Stone, Morley O.

Lewis, Meriwether; Clark, William; Floyd, Charles (1904), Original journals of the Lewis and Clark Expedition, 1804–1806, vol.1, p.257 . Rattlesnakes travel with their rattles held up to protect them from damage, but in spite of this precaution, their day-to-day activities in the wild still cause them to regularly break off end segments. Because of this, the number of rattles on its tail is not related to the age of a rattlesnake. [1] [49] [50]

The rattlesnake became a symbolic animal for the Colonials during the Revolutionary War period, and is depicted prominently on the Gadsden Flag. It continues to be used as a symbol by the United States military, and political movements within the United States. a b c Allf, Bradley C.; Durst, Paul A. P.; Pfennig, David W. (2016).

Females secrete small amounts of sex pheromones, which leave a trail the males follow using their tongues and Jacobson's organs as guides. [66] Once a receptive female has been located, the male often spends several days following her around (a behavior not common outside of the mating season), frequently touching and rubbing her in an attempt to stimulate her.
