what type of venom does a rattlesnake have
Rattlesnake The venom is hemotoxic, destroying tissue, causing necrosis and coagulopathy (disrupted blood clotting).[31] 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.[31][32][33] Although it has a comparatively low venom yield,[34] 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 LD50 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 LD50 studies in laboratory mice.[35]
Rattlesnake An estimated 7,000 to 8,000 people are bitten by venomous snakes in the United States each year, with about five deaths.[70] The most important factor in survival following a severe envenomation is the time elapsed between the bite and treatment. Most deaths occur between six and 48 hours after the bite. If antivenom treatment is given within two hours of the bite, the probability of recovery is greater than 99%.[71]

Snake venom The glands that secrete the zootoxins are a modification of the parotid salivary gland found in other vertebrates, and are usually situated on each side of the head, below and behind the eye, and encapsulated in a muscular sheath. The glands have large alveoli in which the synthesized venom is stored before being conveyed by a duct to the base of channeled or tubular fangs through which it is ejected.[3][4]
