The greater weever is a small sea fish that buries itself in shallow sand along the eastern Atlantic coast and in the Mediterranean and Black Seas. Its spines carry a venom that causes intense pain, so it is one of the most dangerous fishes in the Mediterranean for swimmers.1

它吃什么？

It is an ambush predator that waits buried in sand during the day, with only its eyes and the tip of its dorsal fin showing. It attacks prey that come close in a swift, sudden movement, mainly small fish, decapods and mysids.1

毒液之力

有毒的刺

锋利的刺带着毒液。踩到或抓住它会很疼。

它的毒液会造成什么？

The venom contains a large protein called Dracotoxin, which can be lethal in high enough doses. It damages cell membranes, and the sting is followed by a short period of tissue changes around the wound. The best-known effect is excruciating pain that begins shortly after the sting and can last from a few hours to days.1

它对人有多危险？

对人的危险: 严重如果它的刺扎到你，要去看医生。死亡非常罕见。

The most common incident happens when a bather steps, jumps or falls onto a buried greater weever in shallow water, especially in summer. Fishermen handling fish caught in nets are also at risk. The pain can reach 10 out of 10 on the numeric rating scale, and some stings have caused pain for months, though this is rare. Reported fatal accidents exist, but these are widely believed to be due to secondary infections and sepsis rather than the toxin itself.1

如果它的刺扎到你

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。
如果它的刺扎到你：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

Its venom glands sit in the skin, and the sting works through a groove along each spine that carries the venom into the wound.1

It is classed as one of the most venomous fishes in the Mediterranean.1

The record weight is 1.74 kg, for a specimen caught off La Gomera in the Canary Islands in 2005.1

Its diet changes with size: small mysids are the most common prey for fish under 20 cm, while cephalopods and fish make up a bigger share of the diet in larger fish.1

谣言粉碎机

谣言： A weever sting is often thought to be fatal because of the venom itself.

真相： Reported fatal accidents are widely believed to be caused by secondary infections and sepsis rather than the toxin itself.1
