The sidewinder is a small rattlesnake that lives in the deserts of the south-western United States and north-western Mexico. It gets its name from the unusual sideways way it moves over loose sand. It is venomous, but its venom is weaker than that of many other rattlesnakes.1

怎样认出它

Small, measuring 43 to 80 cm in total length including the tail.1
Raised scales above the eyes give it horns.1
The ground colour may be cream, buff, yellowish-brown, pink or ash grey, with 28 to 47 darker blotches along the back.1
It moves with a sidewinding motion, leaving a J-shaped track in the sand with the tip of the hook pointing in the direction of travel.1
Females are larger than males, which is unusual among United States rattlesnakes.1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

The venom causes pain, swelling and bruising, and can create bleeding blisters. Symptoms can include nausea, dizziness, chills, blood clotting disorders and shock. In one recorded case, a bitten man's whole arm was badly swollen and very painful within about 2.5 hours.1

它对人有多危险？

对人的危险: 严重被咬了要去看医生。死亡非常罕见。

Its venom is weaker than that of many other rattlesnakes, and its venom glands are smaller, so it is less dangerous than its larger relatives. Any rattlesnake bite can still be fatal and should be taken seriously.1

好消息：医生有药（抗毒血清）或治疗方法。1

如果它咬人

Seek medical attention immediately after any rattlesnake bite. Consult a local expert or regional poison control centre before giving antivenom.1
让人保持安静不动，被咬的肢体与心脏保持同一高度，摘下戒指和紧身物品，尽快送医院。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

The AIM-9 Sidewinder missile was named after this snake, because both use infrared signals to track their targets.1

Juveniles and adults use different hunting methods. Juveniles lure lizards with fast tail movements that look like a moth or slower ones that look like a caterpillar.1

The raised scales above its eyes may shade the eyes or stop sand drifting over them. When the snake strikes against a burrow roof, pressure on these horns folds them down, which is thought to protect the eyes.1

Newborn sidewinders huddle together in a burrow for their first week or so, plugging the entrance during the day. Their combined body heat keeps the group at an average of about 32 °C, which is warm enough for shedding.1

Sidewinding is also used by other desert snakes, such as the horned adder and Peringuey's adder, and by robots that copy this movement.1
