Mottled spinefoot

Siganus fuscescens

名字的由來： The specific name fuscescens means "darkened", thought to refer to its dark upper body.1

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

有毒液的棘刺吃：植物

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The mottled spinefoot is a marine fish that lives in warm coastal waters of the Western Pacific and eastern Indian Oceans. It has venomous spines on its fins, so it is best to leave it alone in the water. It is also an important food fish in many places.1

It lives in shallow coastal waters, usually as deep as 50 m, among algae, sea grass, coral and rocky reefs. It is often found in large estuaries. In Australia its range runs from Busselton in Western Australia around the tropical north coast to the Nadgee River in southern New South Wales.1

牠吃什麼？

Juveniles mainly eat filamentous algae. Adults prefer leafy algae and sea grass.1

怎麼認出牠

Moderately slender, flattened body1
Overall colour greenish-grey to brown, fading to silvery on the lower body1
Many small light-bluish spots on the flanks1
A slender brown bar along the upper edge of the gill cover1
Adults show a mottled pattern when asleep or threatened1

常被誤認為： It is very similar in appearance to the white-spotted spinefoot (Siganus canaliculatus), and the two are sometimes confused. They often live in the same areas.1

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？

It has venomous spines in its dorsal and pelvic fins. The venom is similar to that of stonefishes. It can cause sharp pain, bleeding and numbness at the puncture site.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The venom is usually non-lethal.1

牠害怕時會做什麼？

When threatened, adults adopt a mottled pattern and may use their venomous spines.1

如果牠的棘刺刺到你

Soaking the affected area in water of around 45°C could help eliminate or ease the pain.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

小知識

Fish of this species form schools. Larvae gather in groups of about 200, and may hold as many as 5,000.1

Juveniles are often dried and sold in large quantities, while adults are sold fresh.1

Fish more than two years old may spawn more than once in a season.1
