The mamushi is a pit viper, a type of snake that has heat-sensing pits between its eyes and nostrils. It lives in Japan, in places such as swamps, meadows and farmland. It matters because its bite is one of the most dangerous of Japan's snakes.1

生活在

Japan only. There is no evidence it occurs in the Ryukyu Islands.1

怎样认出它

Background colour is pale grey, reddish-brown or yellow-brown.1
A series of irregular blotches runs along the body. Each blotch has a black border and often a lighter centre.1
The head is dark brown or black, with beige or pale-grey sides.1
Adults are typically 45 to 81 cm long.1
It has excellent camouflage and often hides among plants or leaf litter.1

常被误认为： It is similar to the cottonmouths and copperheads (Agkistrodon) of the Americas, and it was long considered part of the same group.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 mostly haemolytic, meaning it breaks down red blood cells. It also contains two neurotoxins, which attack the nerves, and an anticoagulant, which stops blood from clotting. Reported effects include kidney failure, visual disturbances and palsy (paralysis).1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

About 2000 to 3000 people in Japan are bitten by a mamushi each year. Approximately 10 die annually. Severe bites require intensive care, and typical bite victims need about one week of hospital treatment.1

好消息：医生有药（抗毒血清）或治疗方法。1

如果它咬人

Treatment is given in hospital. It involves cutting the wound to remove venom and injecting mamushi antivenom. Pregnant women who are bitten have had miscarriages, so medical care is essential.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

Recovery takes a long time. Bite victims may need several months to fully recover, even after hospital treatment and weeks of follow-up care.1

It is highly resistant to its own venom because its blood contains neutralising factors, including phospholipase A2 (PLA2) inhibitors.1

Its beta-toxin acts before the nerve junction, so anticholinesterase drugs cannot block or treat its effects.1

Its venom contains a peptide called ablomin, which is very similar in amino acid sequence to helothermine, a venom peptide of the Mexican beaded lizard.1

It is considered one of the most venomous snakes in Japan, along with the yamakagashi and the Okinawan habu.1

Its venom varies very little across Japan in either potency or effects.1
