它吃什么？

Juveniles mainly eat frogs and arthropods, while adults mostly eat mammals, and about 80% of an adult's diet is rodents. It is an ambush predator, relying on good camouflage to catch prey. Juveniles also wiggle their white tail tip to lure prey, which looks like an insect larva.1

如果它咬人

Get to a hospital fast. In a recorded case, a patient was treated in hospital with bothropic antivenom and fluid replacement.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。

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 drugs known as ACE inhibitors, used to treat high blood pressure and some types of heart failure, were developed from a peptide found in this snake's venom. Brazilian scientist Sérgio Henrique Ferreira developed them in 1965.1

An enzyme derived from the venom, called haemocoagulase, is used as an anti-haemorrhagic drug, meaning it helps stop bleeding.1

Males mate with more than one female, and males sometimes fight over females.1
