Kuhl's maskray is a flat, diamond-shaped stingray with green skin and blue spots. It lives on sandy and muddy seabeds in warm coastal waters from Indonesia to Japan and around most of Australia. Its tail has venomous spines, so it is important to know what it looks like and to keep a safe distance.1

怎样认出它

Flat, diamond-shaped (rhomboid) body that is dark green with blue spots1
Light white underside1
Very short snout with an angular disc1
Bright yellow eyes1
Long tail, about twice the length of the body, with two venomous spines at its base, one large and one medium in size1

常被误认为： It is often confused with the blue-spotted ribbontail ray, which is common in aquaria. The ribbontail has a rounded body, brighter green colouring and more vivid spots. Kuhl's maskray is larger.1

It is very venomous. Its barb can be about 30 cm long.1

它害怕时会做什么？

Its bright colouring warns predators of its venomous spines. It buries itself in sand to hide from predators.1

如果它蜇人

把伤口泡在热水里，水温以不烫伤为限、尽量热（先用你自己的手试一试），泡 30 到 90 分钟。去看医生，尤其是被石头鱼和魟鱼伤到时。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Large sharks such as hammerhead sharks prey on it. A hammerhead pins it down with its head while the ray is in shock and much weaker.1

Its tail is about twice as long as its body and carries two venomous spines.1

Unlike most stingrays, which bury themselves to hunt, Kuhl's maskray buries itself in sand only to hide from predators.1

Its skin is used to make drums, such as the Arab and Turkish darbuka goblet drum and the riq tambourine.1

Two short peptides found in its hydrolysed proteins have shown protective effects against the oxidation of lipids, DNA and proteins. They may be useful as functional food ingredients or nutraceuticals.1
