The eel-tailed catfish is a freshwater fish with a large head, thick lips and a tail that narrows like an eel's. It lives in the Murray-Darling river system in eastern Australia. Its fins carry sharp, venomous spines, so it is important to know it when you are in the water.1

它吃什么？

Juveniles feed on zooplankton and small insects, especially chironomid (midge) larvae. Fish over about 100 mm also eat small fish, and adults eat shrimps, crayfish, midge larvae, molluscs and dragonfly, caddis fly and mayfly larvae.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

事实

Males and females both help: the parents guard the nest of eggs until they hatch.1

The nest is built one or two weeks before spawning, when water reaches 20–24 °C.1

Juveniles often gather in groups, although adults usually live alone.1

Its populations in the southern Murray-Darling have declined so much that most are extinct or nearly so.1
