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

Kaj je?

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

Kako jo prepoznaš

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

Pogosto zamenjujejo z: 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

Moč strupa

Ugrizi

Strup pride ven skozi strupnike ali zobe, ko ugrizne.

Kaj naredi njen strup, ko ugrizne ali piči?

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

Če ugrizne

Imobilizacija s pritiskom: čvrsto ovij elastični povoj čez ugriz in nato navzgor po celem udu, ud imobiliziraj z opornico in poškodovanca drži popolnoma pri miru, dokler ne pride pomoč.
Modroobročkasta hobotnica ali stožčasti polž lahko človeku ustavi dihanje, medtem ko je še pri zavesti: pokliči pomoč in bodi pripravljen dajati umetne vpihe, dokler reševalci ne prevzamejo.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

vredno vedeti

Dejstva

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

Razbijalec mitov

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

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