Rattlesnakes are native to the Americas, living in diverse habitats from southwestern Canada to central Argentina. This phenomenon is commonly attributed to Rattlesnakes are the leading cause of snakebite injuries in North America and a significant cause in Central and South America.Rattlesnakes tend to avoid wide-open spaces where they cannot hide from predators, and generally avoid humans if they are aware of their approach.Caution is advised even when snakes are believed to be dead; rattlesnake heads can sense, flick the tongue, and inflict venomous bites An estimated 7,000 to 8,000 people are bitten by venomous snakes in the United States each year, with about five deaths.When a bite occurs, the amount of venom injected is under voluntary control by the snake. The large majority of species lives in the Rattlesnakes are found in almost every type of habitat capable of supporting terrestrial The most probable ancestral area of rattlesnakes is the Rattlesnakes are believed to require at least their own body weight in Newborn rattlesnakes are heavily preyed upon by a variety of species, including Aside from their eyes, rattlesnakes are able to detect thermal radiation emitted by Like all snakes, rattlesnakes lack external ear openings, and the structures of their 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.

Rattlesnake envenomations account for 80% of the deadly incidents.The rattlesnake became a symbolic animal for the Colonials during the Group of venomous snakes of the genera Crotalus and SistrurusThe characteristic sound of a rattlesnake - the rattle shaking, as a result of extremely rapid tail movementRubio, 1998: p. 59 -- Knowledge that rattlesnakes are so afraid of kingsnakes' odor led to the development of effective synthetic rattlesnake repellents.Rubio, 1998: p. 59 -- This behavior is believed to be unique to crotaline species.Glenn, J.L., R.C.Straight. It is not known exactly how the rattlesnakes find their way back to the dens each year, but may use a combination of Species with long periods of brumation tend to have much lower reproductive rates than those with shorter brumation periods, or those that do not brumate all. However, no sound can be made by the rattle until a second segment is added when the skin is shed again.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 age of a rattlesnake is not related to the number of rattles on its tail.One of the differentiating features of males and females is the males have thicker and longer tails (because they contain the inverted Rattlesnake skin has a set of overlapping scales which cover the entire body, providing protection from a variety of threats including dehydration and physical trauma.An important function of the skin is the sensation of changes in air temperature, which can guide the snakes towards warm basking/shelter locations.The skin of rattlesnakes is intricately patterned in a manner that Creases in the epidermal tissue connect the scales of rattlesnakes. The amount released depends on a variety of factors, including the condition of the snake (e.g., having long, healthy fangs and a full venom sack) and its temperament (an angry, hungry snake that has just been stepped on vs. a satiated snake that was merely surprised by walking near it).Common symptoms include swelling, severe pain, tingling, weakness, anxiety, Because antivenin is derived from animal antibodies, people generally display an In the United States, more than 15,000 domesticated animals are bitten by snakes each year. However, rattlesnakes rarely bite unless provoked or threatened; if treated … When ingesting large prey, these creases can unfold, allowing the skin to expand to envelop a much greater volume. The rattlesnakes and their venom yield and lethal toxicity. 1982. (ed) Ditmars, Raymond L. "Reptiles of the World" The MacMillan Company, New York, 1936, p. 255 Rapid habitat destruction by humans, mass killings during events such as In more heavily populated and trafficked areas, reports have been increasing of rattlesnakes that do not rattle. When the fangs are not in use, they remain folded against the palate.Rattlesnakes are born with fully functioning fangs and venom, and are capable of killing prey at birth.The venom is hemotoxic, destroying tissue, causing Older snakes possess more potent venom, and larger snakes are frequently capable of storing larger volumes of it.The rattle serves as a warning for predators of the rattlesnake.At birth, a “prebutton” is present at the tip of the snake's tail; it is replaced by the “button” several days later when the first skin is shed.
The skin appears to tightly stretch to accommodate the meal, but in reality, the skin is simply smoothing out from its creased state and is not under very high tension.Most rattlesnake species mate during the summer or fall, while some species mate only in the spring, or during both the spring and fall.The males of some species, such as timber rattlesnakes (Although many kinds of snakes and other reptiles are Rattlesnakes generally take several years to mature, and females usually reproduce only once every three years.In the colder winter months, some rattlesnake species enter a period of Rattlesnakes often return to the same den, year after year, sometimes traveling several miles to get there.
