True to its name \u2013 the giant pacific octopus is bigger than any other species of octopus, making them hard to miss and a real presence in our oceans. There\u2019s plenty to learn about these speedy, colour-changing creatures, so let\u2019s dive into everything you should know.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Species<\/h3>\n
\n

What is a Giant Pacific Octopus?<\/h4>\n
\n

The giant pacific octopus (Enteroctopus dofleini<\/em>) is classified as a marine cephalopod<\/a>, which comes from the Greek word for \u2018head-foot\u2019. Squid, cuttlefish and nautiluses are among some of the species also in the cephalopod order.\u00a0<\/strong><\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Appearance<\/h3>\n
\n

What does a giant pacific octopus look like?<\/h4>\n
\n

<\/p>\n

Picture a regular common octopus with its 8 legs and double it in size \u2013 that\u2019s the main difference between the common and giant pacific octopus. Growing on average 10-16 feet, with the largest size ever recorded specimen 30ft, and weighing up to a whopping 110 pounds, we weren\u2019t kidding when we said they\u2019re hard to miss! Alongside their larger-than-life size, they also have longer average lifespans compared to any other species of octopus, often living up to 3-5 years old in the wild.<\/p>\n

<\/p>\n

They\u2019re normally a reddish-brown colour all over their bodies, except for their arms which tend to fade to a light pink or white shade where their suction cups can be found.<\/p>\n

<\/p>\n

Their large heads contain two small plates, forming a protective shell. Giant pacific octopuses also have beaks, which they use to kill and eat their prey, alongside sometimes using it as a defence mechanism. These beaks can inject venom directly into their prey if they come close enough.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Habitat<\/h3>\n
\n

Where do giant pacific octopus live?<\/h4>\n
\n

Native throughout the Pacific Ocean, they inhabit the intertidal zone to depths of 2,000m. Preferring cold, oxygen-rich waters, the giant pacific octopus can be found in Bala California, all the way to Alaska, Russia, Japan and Korea!<\/p>\n

<\/p>\n

Despite them being common, you\u2019re unlikely to spot them in the wild because they tend to spend most of their time hiding in small spaces and crevices. The giant pacific octopus is also nocturnal, so they\u2019re most active during the nighttime.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n\n

Factfile<\/h3>\n

\n

<\/p>\n

1. They have excellent defence mechanisms<\/h4>\n

As with other species of octopus, this species can eject a cloud of toxic ink if they feel threatened, giving them time to propel themselves away. While this might be a well-known fact, what you might not know is that the ink can even be toxic to the giant pacific octopus itself if there\u2019s a lack of water flow to clear it.<\/p>\n

2. They have 3 hearts!<\/h4>\n

Did you know that all octopuses have 3 hearts<\/a>? Well now you do! Two of their hearts pump blue blood across the gills, while one circulates blood around the body. If you\u2019re wondering why their blood is blue rather than red, this is because it uses a copper-based protein called hemocyanin to carry oxygen around the octopus\u2019 body.<\/p>\n

3. The giant pacific octopus doesn\u2019t have bones<\/h4>\n

As an invertebrate, this means that the giant pacific octopus has no bones in its body. In fact, they\u2019re made up of 90% muscle, which helps them squeeze into tiny gaps and hide! The hardest part of their body is their beak, so as long as they can squeeze their beak through a gap, the rest of their body can follow. They are known as the Houdini\u2019s of the animal kingdom!<\/p>\n

4. Giant pacific octopuses are highly intelligent<\/h4>\n

That\u2019s right \u2013 thanks to their excellent working memory, this octopus species along with others is known to be a clever creature<\/a>. They show off their skills by solving puzzles and mazes, remembering routes, displaying emotions and personalities, and even playing with toys. Their memory also means they\u2019ve been known to recognise individuals, including other octopus and human faces. This is one of the reasons that enrichment activities in captivity are so important to keep their brain active and provide a good quality of life.<\/p>\n

5. Despite their large size, their diets consist of much smaller food<\/h4>\n

You might be shocked to find out that despite being such giants in the ocean, their main diet consists of smaller fish and invertebrates like lobsters and shrimp. They hide in smaller spaces to sneak up on their prey and can squeeze them using their muscular bodies.<\/p>\n
