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

It lives on the seabed from the intertidal zone down to depths of about 300 m (980 ft). It is a shallow-water animal and is found throughout much of its range in these habitats.1

Ano ang kinakain nito?
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

Paano ito makikilala

  • 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

Madalas mapagkamalang: 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

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

Kung kumagat ito

  • Pressure immobilisation: balutin nang mahigpit ng elastic bandage ang kagat at pataas sa buong braso o binti, lagyan ng splint, at panatilihing ganap na hindi gumagalaw ang tao hanggang dumating ang tulong.
  • Ang blue-ringed octopus o cone snail ay puwedeng magpahinto sa paghinga ng tao habang gising pa siya: tumawag ng tulong at maging handang magbigay ng rescue breaths hanggang pumalit ang ambulansya.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

  • Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
  • Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
  • Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

1

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

2

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

3

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

4

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

5

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

Myth buster

Mito: Because captive animals were active at night, many people believed it hunts only at night.

Totoo: A study in Puget Sound, Washington, found that a local population was likely active during the day (diurnal).1
