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

它吃什么？

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

它对人有多危险？

对人的危险: 严重被蜇了要去看医生。死亡非常罕见。

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

它害怕时会做什么？

When threatened, it raises its tail over its back with the spine facing forward and waves it back and forth.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

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

谣言粉碎机

谣言： 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
