How big is an octopus? 

In this brief guide, we’ll address the search query: “How big is an octopus?” Also, we’ll explore what an octopus is, what an octopus’s diet is, where octopuses are distributed, and what their role in the environment is. 

How big is an octopus?

The size of an octopus will depend on the species. For example, the largest octopus species, the giant pacific octopus (Enteroctopus dofleini) can measure up to five meters from head to legs and weigh just shy of 50 kilograms. 

A common octopus, on the other hand, can measure up to 90 centimeters and weigh up to 10 kilograms. 

An octopus’s size will not only depend on the species but also on its growth stage, as naturally, octopuses that have yet to reach the adult stage, will not have reached their full size. 

Octopus species vary in size, and they’re regarded as outstandingly intelligent animals, that are not only a subject of study but also have culinary significance in many countries. 

What is an octopus? 

An octopus is a mollusk. They are invertebrates, and cephalopods and are characterized by having eight legs. 

Anatomically, their mouth and beak are located at the center of their body, underneath the head and legs. Octopuses also produce clouds of ink as a defense mechanism to escape from predators and are carnivorous themselves. 

Octopuses are prized both in scientific studies that seek to understand their degrees of intelligence and problem-solving abilities, while also constituting a culinary tradition in Asian and Mediterranean cuisine. 

Currently, there is a debate on whether octopuses (which are sourced from natural populations) should be farmed, due to the ethical implications that raising an intelligent species for slaughter would entail. 

What is in an octopus’s diet? 

An octopus’s diet consists of smaller fish, invertebrates such as squids, lobsters, mussels, sharks, clams, crabs, snails, and even other smaller octopuses. 

In captivity, they have been known to exhibit cannibalistic tendencies, and in the wild, they live alone, foraging their environments for the above-listed food types. 

It is important to note that despite their soft bodies, octopuses possess beaks that can inject poison, and break through tough shells. This makes ingesting foods such as mollusks and shellfish easier. 

Each species has a certain type of venom, capable of immobilizing and rendering its prey defenseless.

They’re nocturnal hunters that search the floors of shallow waters and pounce upon unsuspecting morsels, often by using their chromatophores to blend into their surroundings and then ambushing their prey. 

Where are octopuses distributed? 

Octopuses are distributed throughout the world, in all oceans. Though some species are endemic to specific environments, and as a result,  the exact range of an octopus will depend on the species and its growth stage. 

Octopuses can be found in coastal waters, and many of them hunt in shallow waters near coral reefs, which are often teeming with other species such as bony fish, eels, crustaceans, and on occasion, even other octopuses. 

Some species have, however, developed an affinity for deeper, colder waters, while others live near thermal waters. 

Thus far, no species are reported to live in freshwater bodies. 

What is their role in the environment? 

In the environment, octopuses play important roles as intermediate consumers. This means that they are both predators and prey. 

As predators, octopuses cull out and moderate the populations of the species they prey upon. This helps populations maintain numbers within environment thresholds. 

As prey, they transfer the nutrients they ingest from smaller species to larger species by providing nourishment. 

Their role as intermediate consumers makes them essential parts of the food chain. They not only provide nourishment to larger species such as sharks, toothed whales, and seals, but they are also at the center of many popular recipes in Asian and European cuisine. 

Octopus meat is nourishing and can be used to prepare many savory dishes such as pastries, salads, soups, stews, and stir-fried dishes. 

As we’ve mentioned above, octopuses are sourced from wild populations, and this has environmental implications. 

Many enthusiasts advocate for the establishment of farms, as this would relieve some of the pressure from natural populations and prevent over-fishing, though the movement has detractors.

Octopuses are highly intelligent creatures who have demonstrated cognitive abilities beyond that of many other animals, such as problem-solving skills. Scientists, therefore, argue that for this reason, it is unethical to farm them, coupled with their cannibalistic tendencies in captivity. 

Ultimately consumers will have the deciding vote on whether these ambitious farming projects materialize.
