The mottled spinefoot is a marine fish that lives in warm coastal waters of the Western Pacific and eastern Indian Oceans. It has venomous spines on its fins, so it is best to leave it alone in the water. It is also an important food fish in many places.1

怎样认出它

Moderately slender, flattened body1
Overall colour greenish-grey to brown, fading to silvery on the lower body1
Many small light-bluish spots on the flanks1
A slender brown bar along the upper edge of the gill cover1
Adults show a mottled pattern when asleep or threatened1

常被误认为： It is very similar in appearance to the white-spotted spinefoot (Siganus canaliculatus), and the two are sometimes confused. They often live in the same areas.1

如果它的刺扎到你

Soaking the affected area in water of around 45°C could help eliminate or ease the pain.1
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。

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
