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]

Rattlesnakes tend to avoid developed areas, preferring undisturbed, natural habitats. Rapid habitat destruction by humans, mass killings during events such as rattlesnake round-ups, and deliberate extermination campaigns all pose threats to rattlesnake populations in many areas. Several species, such as the timber rattlesnake, massasauga, and canebrake rattlesnake, are listed as threatened or endangered in many U.S. states. [79] Phillips, Steven J.; etal., eds. (2009).

These powerful magnets are tons of fun, great for hand-eye coordination, and are a fantastic stress reliever. MADE FROM SAFE COMPONENTS An important function of the skin is the sensation of changes in air temperature, which can guide the snakes towards warm basking/shelter locations. [62] All snakes are ectotherms. To maintain a stable body temperature, they exchange heat with their external environments. Snakes often move into open, sunny areas to absorb heat from the sun and warmed earth, a behavior known as basking. Nerves in the skin regulate the flow of blood into the veins near the surface.

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. Slatter, Douglas H. (2002). Textbook of small animal surgery. Elsevier Health Sciences. p.267. ISBN 978-0-7216-8607-3.

In the United States, more than 15,000 domesticated animals are bitten by snakes each year. Rattlesnake envenomations account for 80% of the deadly incidents.

Keeping the cold out in the winter months is a must for everyone. Draughty leaks let cold air in, increase your electricity bills and make for a very cold night in.
