It lives in shallow coastal waters on coral reefs and nearby sandy flats, down to about 30 m. It is also common in the intertidal zone and tidal pools, and near seagrass beds. During the day it hides alone in caves or under coral ledges and debris, including shipwrecks, often with only its tail showing.1

游泳, 粗略估計

牠吃什麼？

It feeds on molluscs, worms, shrimps, crabs and small bony fishes. It digs sand pits to find prey, then traps the food under its body and moves it into its mouth with its disc.1

怎麼認出牠

Numerous circular, neon blue spots on a yellowish brown or green back, with the spots smaller and denser towards the edge of the disc1
Two stripes of the same blue running along the tail1
Bright yellow eyes and a white belly1
Oval, smooth-edged disc, with a thick tail about 1.5 times the length of the disc and one or two serrated spines near the base1

毒液力量

螫

毒液從螫針出來。

牠的毒液有什麼作用？

Its tail carries one or two serrated spines that deliver venom when it stings. The sting can cause an excruciating wound.1

牠對人有多危險？

對人的危險: 嚴重被螫了需要看醫生。死亡案例非常罕見。

It is timid and harmless towards people unless provoked, and it prefers to flee. It is capable of injuring people with its venomous tail spines.1

牠害怕時會做什麼？

When threatened, it flees at high speed in a zigzag pattern to throw off pursuers.1

如果牠螫人

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。
如果被牠螫了：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

It has been seen raising the edges of its disc and pelvic fins to attract cleaning by the bluestreak cleaner wrasse.1

Goatfish often follow foraging rays to catch food the ray misses.1

Most specimens struggle in home aquariums, and many stop feeding or die for no clear reason, so public aquariums have had more success keeping them.1

Unlike many other stingrays, it seldom buries itself in sand.1
