牠吃什麼？

It feeds almost entirely on the aquatic young of mayflies, stoneflies and caddisflies, and only rarely on true flies.1

Mostly smooth skin, with a small patch of tiny bumps at the centre of the back or none at all1
Plain brown or grey on top, paler towards the edge of the disk1
White underneath, with white-edged fins1
Whip-like tail with one or more stinging spines, grows to about 40 cm wide1

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 tail spine can inflict a painful wound and is potentially injurious to people wading in its rivers.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

Local Hausa people call it kunaman ruwa, which means water scorpion.1

It is one of only two freshwater stingrays in Africa.1

Its electrical sense organs are smaller and simpler than those of sea stingrays, which suits life in fresh water.1

It is caught by accident and sold fresh or smoked as food.1

Males may live up to five years and females up to seven years.1
