Spotted scat

Scatophagus argus

名字的由來： The name argus comes from Argus, a mythical guardian with a hundred eyes, and refers to the spots on the fish's body. The genus name Scatophagus means "dung eater".1

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

有毒液的魚

有毒液的棘刺吃：每樣都來一點

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The spotted scat is a fish with a rectangular body covered in brown spots. It lives in shallow, muddy coastal waters across the Indo-Pacific, from the Persian Gulf to southeastern Australia. It can sting with small spines near its front, which makes it worth knowing about.1

It lives in sheltered, shallow coastal waters such as estuaries, harbours, mangrove pools and the lower parts of freshwater streams, especially where minerals are concentrated. Juveniles float in the surface film of the water.1

牠吃什麼？

Adults eat a wide range of food, and a 1992 study of adults in the Philippines found they mainly ate plant matter. Juveniles prefer zooplankton, which are tiny animals that drift in the water.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？

The spotted scat has small spines in its front parts that inject venom when it stings. The venom causes great pain and dizziness.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。

Its sting causes great pain and dizziness. Some people catch and eat it in its native waters, so fishers and anyone handling the fish are most at risk of being stung.1

如果牠的棘刺刺到你

Treatment is often done by soaking the sting site in hot water.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

Young scats live in freshwater and move to saltwater as they mature.1

The spotted scat comes in two colour forms, a green scat and a ruby or red scat.1

Spotted scats live in schools.1

The spotted scat is a popular aquarium fish.1

Females become sexually mature at around 7 to 9 months old and about 150 g in weight, while males mature at a smaller size.1

破解迷思

迷思： Scats are named because they feed on dung and offal.

真相： The name may be misleading. The habit of eating offal has not been confirmed in diet studies.1
