The broad-banded copperhead is a venomous pit viper, a type of snake that uses heat-sensing pits between its eyes and nostrils to find prey. It lives in the central United States, mainly Oklahoma and central Texas, and in parts of northern Mexico. For a long time it was thought to be a form of the eastern copperhead, but it is now treated as its own species.1

它吃什么？

It is a diet generalist, but small rodents such as rats and mice make up most of what it eats. It is mainly an ambush predator that finds prey using smell, sight and heat. It usually bites larger prey and lets the venom work, but it holds birds and smaller prey until they die.1

怎样认出它

Typically light tan with wide, darker brown crossbands, which give it its common name.1
Colour varies by location, from red-brown to grey-brown.1
The bands stay even in width. The eastern copperhead's bands narrow at the spine to form hourglass shapes.1
Young snakes have a bright green-yellow tail tip that fades to grey or brown at about one year old.1

常被误认为： The eastern copperhead overlaps with this species in the south of its range, and the two can be hard to tell apart there. Look at the bands: the broad-banded copperhead has even bands, while the eastern copperhead's bands narrow at the spine.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？

Its venom is hemotoxic, meaning it mainly damages blood and tissue. It is injected through hinged, hollow fangs in a single quick strike. The bite can cause localised swelling, necrosis (death of tissue at the bite site) and severe pain.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。

Copperhead venom is not considered life-threatening to an otherwise healthy adult. Any bite from a venomous snake should still be treated as serious.1

好消息：医生有药（抗毒血清）或治疗方法。1

如果它咬人

Any bite from a venomous snake should be treated as serious, and medical treatment should be sought. Doctors may use CroFab in severe cases, which is made using cottonmouth venom because no antivenin is made specifically for copperheads.1

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

值得了解

事实

It can swim across large bodies of water and has been found swimming more than a quarter of a mile from shore in Lake Texoma, Texas.1

In one radio tracking study, a snake was found with a Texas horned lizard inside it. The snake later passed the tracking device without harm.1

Although it is not tree-dwelling, it can climb and has been seen coiled and resting in trees about 2 metres above the ground.1

Some copperheads in Kansas are hybrids of the eastern and broad-banded copperheads. Genetic studies in that state found no genetically pure broad-banded copperheads.1

It is known by colourful local names, including thunder snake, rattlesnake pilot and red eye.1

谣言粉碎机

谣言： Copperhead bites are harmless.

真相： A bite is not life-threatening to a healthy adult, but it can cause swelling, tissue death and severe pain. Any bite should be treated seriously and medical care sought.1
