它吃什么？

In captivity it is fed on cockroaches and crickets. Cockroaches are easy prey because they do not hide, so the scorpion can catch them easily.1

毒液之力

蜇伤

毒液通过蜇刺出来。

它的毒液会造成什么？

The venom contains the neurotoxins Tst1 and Tst26, which act on the nerves. Lab tests on mice give an LD50 of 0.575 mg/kg, a measure of how strong a venom is, which is significant. Reported symptoms include local pain, numbness, swelling, burning and itching, plus sweating, headache, vomiting, nausea, tremors, agitation, dizziness, low blood pressure and difficulty breathing.1

它对人有多危险？

对人的危险: 严重被蜇了要去看医生。死亡非常罕见。

A study in Bahia state, Brazil, recorded 237 people stung by this species between January 1982 and December 1995. Symptoms were recorded for only 90 of them, so the full picture is unclear.1

如果它蜇人

Put an ice pack on the sting to cool it. Go to hospital and ask to be checked for serious complications such as acute kidney injury and pancreatitis. Venom extraction kits were tested and found not to work; they can cause more damage to the wound because of the suction.1
用冰袋冷敷蜇伤处，让人保持不动。尽快就医，尤其是儿童：有些蝎子对孩子是致命的。

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。
如果被它蜇了：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

Females can reproduce without a male, a process called facultative parthenogenesis.1

It does not need to drink water, because it gets moisture from its prey.1

Its venom contains two neurotoxins, Tst1 and Tst26, which affect the nerves.1

Females can have as many as 16 young in one brood, with an average of 8.1

It takes about a year for this scorpion to mature into an adult, which makes it a fast-growing species.1
