牠吃什麼？

It eats mostly crustaceans, including crabs, shrimp and prawns, which make up about 95% of its diet. It also eats worms, other invertebrates and bony fish. Unlike many catfish, it feeds throughout the water column rather than mainly on the bottom.1

怎麼認出牠

Blue-grey to dark brown on the back, with a light grey belly.1
Deeply forked tail.1
Long, serrated venomous spines on the pectoral and dorsal fins.1
A small hump on the back that looks somewhat like a wave.1
A white or pale blue anal fin, and a fleshy extension on the dorsal spine.1

常被誤認為： It resembles the hardhead catfish. The gafftopsail can be told apart by the distinctive fleshy extension on its dorsal spine.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 spines can cause painful wounds, so care should be taken when handling this fish.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

值得知道

小知識

Males carry the eggs in their mouths, and do not feed while they are brooding eggs or young.1

Anglers consider it a strong fighter, and it is attracted to the sound of struggling fish.1

Unlike most catfish, which mainly feed on the bottom, this fish feeds throughout the water column.1

Young fish are about 5 cm long when they hatch from the eggs.1
