Lesser weever
有毒液的棘刺The lesser weever is a small, venomous fish that lies buried in sand on the sea floor, often close to the shore. Its venom is strong, and it is considered one of Europe's most dangerous weever species because it lives near beaches where people swim.1

毒液力量
尖銳的棘刺帶著毒液。踩到或抓到牠都會很痛。
牠的毒液有什麼作用?
The venom contains trachinine, a cytolysin (a substance that breaks down cells), along with serotonin, histamine-releasing substances and various enzymes. The sting causes acute and intense pain that often spreads to the area around the limb, and it peaks about 30 minutes after the sting. Swelling, redness, numbness, tingling, nausea and vomiting are common, and rare severe effects include abnormal heart rhythms, seizures, decreased blood pressure and unconsciousness.1
牠對人有多危險?
對人的危險: 嚴重如果被牠的棘刺刺到,要去看醫生。死亡案例非常罕見。The lesser weever can sting swimmers badly if they disturb it in the water, and fishermen can be stung when cleaning their nets. Because of its venom and its occurrence near beaches, it is considered one of Europe's most dangerous weever species. Some pain may continue for up to 24 hours.1
牠害怕時會做什麼?
It rests buried in the sand with only its eyes and the tip of its first dorsal fin exposed, and it stings when disturbed.1
如果牠的棘刺刺到你
- Wash the wound, then immerse it in very hot water for at least an hour to ease the pain and help destroy the protein-based venom. The water should be 40 °C (104 °F) or as hot as the patient can tolerate. Reassure the patient that the sting is relatively harmless.1
- 把傷口泡在熱水裡,水溫要在傷者能忍受、又不會燙傷的範圍內(先用你自己的手試水溫),泡 30 到 90 分鐘。要就醫,特別是被石頭魚和魟魚刺傷時。
一定要先打緊急電話(112、000、911)。這是一般急救指引,不是醫療建議。 急救基本知識
注意安全
- 絕對不要碰、抓或捉弄野生動物,就算是很小的動物,就算牠看起來在睡覺或已經死了也一樣。
- 給牠空間。如果遇到了,保持冷靜,慢慢往後退,讓牠自己離開。
- 如果被牠的棘刺刺到:保持冷靜,保持不動,打緊急電話(112、000、911)或趕快去醫院。記住牠的樣子,有照片會很有幫助。
牠不是想來抓你。牠用毒液來捕捉食物或保護自己,而且牠更想躲起來。 更多安全知識
