只是會痛不要碰會痛，但不會對你造成嚴重傷害。

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The orange-spotted spinefoot is a small, spotted sea fish from the rabbitfish family. It lives in warm coastal waters of the Indian and Pacific Oceans, often over reefs and mangroves. Its spines carry venom, so it is one to admire from a distance.1

牠吃什麼？

It feeds mainly on benthic algae, which are algae growing on the seabed. It is unusual for a rabbitfish in being active at night.1

怎麼認出牠

Body is dusky blue above and silvery below1
A single large yellow-orange spot sits below the soft-rayed part of the dorsal fin, near the tail1
Several smaller reddish-brown spots run along the sides1
A forward-pointing spine sits in front of the dorsal fin1
Adults reach about 42 cm in total length, but 25 cm is more typical1

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？

The spines of the dorsal, anal and pelvic fins have grooves containing venom glands. Venom from a related species was found to be similar to the venom of stonefishes.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 wound from the spines may be relatively painful to people, but it is usually not dangerous.1

牠害怕時會做什麼？

It uses its venomous spines for self-defence.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

牠有多長？

跟 2,5 根香蕉頭尾相接一樣長跟 13 塊玩具積木排成一排一樣長可以在 33 秒內游完一座大游泳池（50 公尺）

Orange-spotted spinefoot 跟「你」比起來有多大？

只是在你的瀏覽器裡做算術。什麼都不會儲存，也不會傳送到任何地方。

牠有多快？

一個正在游泳的人 大約 3 km/h (1,9 mph)

Orange-spotted spinefoot 大約 5,5 km/h (3,4 mph)

奧運游泳選手 大約 8 km/h (5 mph)

值得知道

小知識

Unlike most rabbitfish, it may be active at night.1

Adults form schools of between 10 and 15 fish.1

Rabbitfish are considered good candidates for aquaculture, and this species is hardy in culture.1

It is fished with set nets and fish traps, and is sold as fresh fish in markets.1
