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

Toads make up most of its diet, which sets it apart from many snakes that mainly eat other animals.1

Hatchlings are already 15 to 18 cm long, which is a large size for a newborn snake.1

Its upturned snout is an adaptation that gives the species its common name.1

The Alabama Department of Conservation and Natural Resources lists it as possibly extirpated (locally extinct) in that state.1

It is classified as Vulnerable on the IUCN Red List, meaning it faces a high risk of extinction in the wild.1
