它的毒液会造成什么?

Its venom causes pain, swelling, redness, bruising and pale skin at the bite, and can kill skin tissue (dermonecrosis). It can also cause hemolysis, the breakdown of red blood cells, which can lead to anaemia. In a study of 81 cases, two people developed acute kidney injury.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。

It is highly venomous. In the state of São Paulo alone, Brazil, it causes the more serious viscerocutaneous loxoscelism (a bite illness affecting the skin and internal organs) in 3.1% of cases.1

如果它咬人

  • 清洗咬伤处,用冰袋冷敷止痛。如果疼得厉害、疼痛扩散或感到不适,就去看医生。

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
