Octopuses are intelligent creatures that are best known for their unique physical features. These creatures live in the ocean, have eight arms, bulbous heads, and are boneless.
Several researchers have spent time studying Octopuses and their many unique characteristics. They are indeed intriguing. And with over 200 species, there is so much to know about them.
So, let’s answer the question.
What Is A Group Of Octopus Called?
Octopuses live alone for most of their lives, if not all their lives. So, there is no name for a group of octopuses because they don’t live in groups. They are solitary creatures that live underwater for all their lives.
According to the world animal foundation, there are 289 species in the order Octopoda. The name Octopeda encompasses all the animals in the genus Octopus, which means “eight feet” in Greek. Here are a few distinctive features that best describe the Octopus
The Octopuses’ arm works like it has a control panel outside its body. Unlike other mollusks, a large portion of the Octopus’ neurons is in its arms.
This presence of neurons means that it can use two arms simultaneously, not in the way that most animals would. For instance, It can be searching a cave with one hand and cracking a shellfish with the other.
Some species of Octopus have warts. These warts are commonly in the Graneledone genus (G. Pacifica and G. Verrucosa). Telling the two species apart was difficult until the discovery of the protrusions on their mantles.
These warts, the distance between them, and how they spread across the octopus’ arm enable us to tell the difference between the two species.
They also have no protective shells or skeletons. They have soft bodies that allow them to squeeze into any corner in the deep sea. Their mantle (bulbous sack-like body) is on the head of the Octopus.
Almost every part of the Octopus is squishy. The only hard part of the Octopus is its beak. This beak that looks like that of a parrot is directly under where their arms meet.
Where Do Octopus Live?
It is not news that Octopuses live in oceans. But they don’t just live randomly in the oceans. Some of them live close to the water surface in crevices, reefs, and shells. While the others live deep in the sea, in caves
What Do Octopus Eat?
Octopuses are carnivores. That is, they eat flesh. Their meals range from birds to fish to sharks and many other inhabitants of the ocean. They eat by dropping down on their prey, enveloping them with their arms before pushing them into their mouth.
The Size Of Octopus
The largest Octopus, which is the giant Pacific Octopus, typically weighs about 50kg. National geographic records show that a giant Pacific Octopus once weighed 272kg.
The smallest Octopus, the octopus wolfi, weighs less than a gram. In contrast, the common Octopus weighs about 3-10 kg. Different octopuses have different sizes.
Octopuses don’t live for long. Some live for a short period of five months, while other species live for about five years. According to the world animal foundation, the more giant the Octopus, the longer they live.
But no matter the species of Octopus, they always die soon after mating. The reproductive process starts when the male Octopus puts a specialized arm into the female’s mantle cavity. The arm used is usually the third arm on the right. On some occasions, the male gives the female the sperm.
The average female Octopus lays about two hundred thousand to four hundred thousand eggs. She guards the eggs with all that she’s got until they hatch. She often stops eating till all the eggs have hatched.
Then her body undergoes cellular suicide. This suicide is her body turning on her and fighting her tissues and organs till she dies. The female isn’t the only one who goes through this; the male dies months after giving his sperm.
The hatched octopuses are called larvae. To survive, they eat other larvae (usually other animals) in the oceans. There is also a possibility that they may get eaten before they mature.
Octopuses are solitary creatures. They don’t often interact with themselves, but they interact for short periods occasionally. Their interactions get limited by their difference in hunting times. Some octopuses hunt at night, while others hunt at dusk or dawn.
A scared octopus would release a dark liquid in the direction of whatever scared them. This dark liquid, called ink, prevents octopuses from being caught or eaten daily.
This escape is because the dark liquid blinds and befuddles their attacker for a brief period, which is usually enough time for them to escape. This released liquid can weaken the attacker’s tasting and smelling abilities.
Another behavioral trait is how they change their colors to blend in with their environment. They can turn brown, pink, green, gray, blue, etc. Some species also can look like other more dangerous inhabitants of the ocean—for example, lionfish.
Lastly, they swim by sucking water into their bodies and shooting it out through the siphon. This process of sucking in and shooting out gives the Octopus the speed they need to swim far away from predators. Octopuses swim fast, but they choose to crawl slowly through the ocean.
Facts About Octopus
There are several facts about octopuses. Some of these facts are mind-blowing. Here are a few facts about Octopus that you should know:
Octopuses have poison:
They don’t have enough poison to kill a human being, but they have enough to paralyze a human being in a few minutes. Research has shown that they have venom inside their bodies. This venom comes from certain bacteria living in their bodies.
Octopuses can open pill bottles:
This fact shouldn’t come as a big shock to you since these creatures can open clam shells without external help. They can open child proof pill bottles without assistance.
They are playful:
Different studies have shown that Octopuses are curious, intelligent, and need stimulating activities. Scientists have confirmed that octopuses can play.
They use tools:
Octopuses have shown that they are intelligent animals, just like dolphins and chimpanzees. People have seen octopus using external objects for different reasons. For example, scientists testify to seeing an octopus gather coconut shells and turn them into a makeshift home.
They have three hearts:
Every Octopus has three hearts. This fact is one of the most popular and intriguing facts about the Octopus. Two of the hearts are responsible for pumping blood through the octopus’ gills. At the same time, the last one is responsible for pumping blood through the octopus’ organs.
They have blue blood:
Octopuses have blue blood because of the hemocyanin in their blood. Hemocyanin is a copper-based protein found in the bloodstream of all Octopus.
They eat their arms:
Octopuses can get bored. In a non-stimulating environment, they can get stressed. Some may out of stress or boredom, start eating their arms. So, studies have shown that Octopuses kept in a tank with decor like shells or flowers are less likely to get bored.
They can hide in plain sight:
An octopus can change its body color in a fraction of a second. Unlike other animals that camouflage, the Octopus doesn’t just switch to the general theme of its environment. It can blend with specific things in the background, plants, rocks, etc.
They do not always have long arms:
Not all Octopuses out there have long arms. The arms of the Opisthoteuthis adorabilis are very short and have webbing between them. As a result, the tiny Octopus appears to be an orange ghost.
They are smart:
Octopuses are about as intelligent as house cats.
They have a history:
The oldest octopus fossil dates from 296 million years ago, millions of years before the dinosaurs existed.
The plural isn’t “octopi”:
According to the Oxford English Dictionary, the standard plural of Octopus is octopuses. As a Greek word, it adheres to the Greek rules for plurals. The term “octopi,” which adheres to Latin plural rules, is incorrect.

The Octopus is an intelligent creature. It is evident in their interaction with humans and with their immediate environment. These creatures with over 200 different species have high chances of surviving in the ocean because of their intelligence and general adaptability.
You can compare their intelligence to the dolphins and chimpanzees for many reasons. This post is an overview of what octopuses in a group are called, alongside amazing facts about them and their different species.
