East Pacific red octopus

Octopus rubescens

只是会疼会疼，但不会对你造成严重伤害。

咬伤吃：肉

The East Pacific red octopus is a small octopus that lives along the North American West Coast. It is the most common shallow-water octopus in much of this region and hunts on the seabed. It is special because scientists have shown it has individual personalities, the first invertebrate found to have them.1

它吃什么？

It is a generalist predator that feeds on gastropods (sea snails), bivalves, crabs and barnacles. It pounces on its prey and changes colour in a set sequence at the moment of capture. When it attacks a bivalve, it drills a hole through the shell and delivers venom, then opens the shell more easily.1

怎样认出它

Its colour can vary from deep brick red to brown, to white, or a mottled mixture of these.1
It can change both its colour and skin texture.1
It has three eyelash-like papillae (small bumps) below each eye.1
Adults usually have a mantle (body) length of 8–10 cm, with arms of 30–40 cm.1

常被误认为： Small individuals of the giant Pacific octopus (Enteroctopus dofleini) can be mistaken for it in the north of its range. The East Pacific red octopus has three eyelash-like papillae below each eye, which the giant Pacific octopus lacks.1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

It uses venom to subdue its prey. After catching a bivalve such as a clam, it drills a hole through the shell near the adductor muscles and injects venom through that hole.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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。

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

值得了解

事实

It was the first invertebrate in which individual personalities were demonstrated.1

In the 2016 Pixar film Finding Dory, a character named Hank is an East Pacific red octopus. The animators gave him seven arms because they could not fit all eight on his model.1

It drills holes in bivalve shells, often near the adductor muscles, to reach the prey inside.1

A 2011 study suggested it may choose prey based on how easily the fat can be digested rather than on calories.1

It was widely thought to be a young giant Pacific octopus before it was described as a species in 1953.1
