Arizona black rattlesnake

Crotalus cerberus

需要看医生很少致命，但被咬了要去看医生。

咬伤吃：肉

The Arizona black rattlesnake is a venomous pit viper, a type of snake that senses heat with pits between its eyes and nostrils. It lives in the southwestern United States, mostly in the mountains of Arizona. It is special because scientists have observed it showing complex social behaviour, and its mothers care for their babies.1

怎样认出它

Ground colour is dark grey, brownish black, reddish brown or blackish.1
Dark blotches run along the back, becoming crossbands just before the tail.1
Some individuals are a uniform dark colour with no clear pattern.1
Some have dark blotches bordered with white, cream or yellow, or a pale body with a lot of yellow.1
A stripe runs from the eye, clearer in lighter-coloured specimens. Adults are less patterned than juveniles.1

常被误认为： It is often incorrectly called a timber rattlesnake.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。

如果它咬人

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

值得了解

事实

The Arizona black rattlesnake is the first snake species observed to show complex social behaviour.1

Adults can change colour quickly, a trick it shares with chameleons and some other lizards.1

Mothers sometimes show cooperative parenting behaviour while they stay with their young.1

Its quick colour change is likely caused by melanin moving inside skin cells, as in the closely related prairie rattlesnake.1

Like all temperate pit vipers, it gives birth to live young rather than laying eggs.1
