咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

如果它咬人

加压固定法：用有弹性的绷带紧紧缠住咬伤处，再缠满整条肢体，用夹板固定，让人完全不动，直到救援到来。
蓝环章鱼或芋螺可能让人在清醒时停止呼吸：立刻呼救，并准备好做人工呼吸，直到救护车接手。

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。
如果被它咬了：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

事实

Octopuses are ranked as the most intelligent invertebrates, and this species can recognise people it often meets and open childproof bottles.1

Its largest suckers can each support about 16 kg.1

The largest individual may have weighed 270 kg, with an arm span of 9.8 m, according to the fisherman who caught it.1

It spends about 94% of its time hidden in dens, kelp or camouflage.1

Unlike most octopuses, which live about one year, it lives three to five years.1

It is the largest octopus species on Earth.1
