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

Leef in

North American West Coast, from the southern Gulf of California to the Gulf of Alaska; may also occur in the western Pacific Ocean1

Stille Oseaan

Tuis

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

Lengte

8 cm tot 10 cm (3,1 in tot 3,9 in)1

Gewig

100 g tot 400 g (4 oz tot 14 oz)1

Topspoed

omtrent 25 km/h (16 mph)

Wat eet dit?

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

Hoe om dit te herken

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

Word dikwels verwar met: 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

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

As dit byt

Drukimmobilisasie: draai 'n stewige elastiese verband oor die byt en dan op oor die hele arm of been, spalk dit en hou die persoon heeltemal stil totdat hulp opdaag.
'n Blouring-seekat of keëlslak kan 'n mens se asemhaling laat stop terwyl hy nog wakker is: roep hulp en wees gereed om asemhaling (mond-tot-mond) te gee totdat die ambulans oorneem.

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

Mite-breker

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

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