The California scorpionfish is a spiny fish that lives on the ocean floor along the Pacific coast of California and Baja California. It stays still among rocks and in caves, where its spotted colours help it blend in. Its spines carry venom, so it is one to leave alone.1

首頁

It lives on rocky bottoms just offshore or in bays, and it also uses underwater caves. It is usually found in water up to about 30 metres deep, though it can go down to 183 metres. People most often meet it when fishing, when it is pulled from the hook.1

長度

43 cm 到 47 cm (1,4 ft 到 1,5 ft)1

最高速度

大約 2 km/h（1,2 mph）

毒液力量

有毒液的棘刺

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？

Its spines contain venom-producing glands. The venom is cardiotoxic, meaning it affects the heart; in laboratory studies it caused changes in blood pressure and heart rhythm. A spine prick can cause severe, throbbing pain, swelling, numbness and discolouration of the finger, with pain spreading up the arm. Nausea, faintness and pale, clammy skin can also occur.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。

It has been responsible for many human injuries and has been called one of the most noxious marine animals in California waters. Fishermen are most often affected when removing the fish from a hook. The effects can feel much like a rattlesnake bite, and one victim developed pericarditis, an inflammation of the lining around the heart. In one reported case, the victim recovered in about two weeks.1

牠害怕時會做什麼？

When pulled from the water, it flares the spines on its fins and gill covers, which makes it difficult to handle.1

如果牠的棘刺刺到你

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

小知識

Its venom is produced in grooves along each spine, and the spine is covered by a thin membrane that is pushed back as it enters the skin, helping to inject the venom.1

It has no swim bladder, which is why it spends most of its time resting on the ocean floor.1

Some individuals have travelled up to 200 km in mark and recapture studies. One fish moved from near Santa Cruz Island to Long Beach over about 14 months.1

The California two-spot octopus preys on it, and the fish will also eat small octopuses of the same kind.1

Its maximum recorded lifespan is 21 years.1

Despite its danger, it is considered a very good food fish once the spines have been avoided, and it is sought after by some Asian communities in Southern California.1
