The round ribbontail ray is a large stingray that lives in warm, shallow seas across the Indo-Pacific, from South Africa to Japan and Australia. It can grow to 1.8 m across, and it is valued by divers for its size and striking look. It has a venomous tail spine, so it is one to admire from a distance.1

牠吃什麼？

It hunts bivalves, crabs, shrimps, and small bony fishes on the seabed. It presses the edge of its disc against the bottom and blows water through its spiracles to uncover prey buried in the sand.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 not aggressive and has been known to approach and investigate divers. If harassed, it can inflict a severe wound with its venomous tail spine. At least one diver has died after being stabbed while trying to ride one.1

牠害怕時會做什麼？

When threatened, it raises its tail over its back with the spine facing forward and waves it back and forth.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 is one of the largest stingray species, reaching 150 kg in weight.1

Females can be pursued by dozens of males during reproductive gatherings, which have been seen in groups of hundreds at Cocos Island.1

Smaller fishes such as jacks and cobia often follow it, feeding on food stirred up by its movements or sheltering behind its body.1

It is mostly active at night and rests motionless during the day, often in caves or under ledges.1

破解迷思

迷思： The round ribbontail ray is an aggressive animal that attacks swimmers.

真相： It is not aggressive. It will defend itself with its venomous tail spine only if it is harassed or provoked.1
