Tako (Octopus): Everything you need to know

What is Tako (Octopus)?

Tako, or octopus in Japanese, is a delicacy popular in Japanese cuisine. Tako can be served raw, grilled, boiled, steamed and even deep-fried as Takoyaki – a popular Japanese snack made with small pieces of Tako. Tako are found throughout the world’s oceans but are particularly abundant in Japan. Delving into the remarkable anatomy and intelligence of octopuses, as well as their distinct behaviours and culinary applications, let’s uncover all there is to know about these captivating creatures.

Anatomy and Physiology

Body structure

Octopuses are invertebrate cephalopods with a soft body, consisting of an outer mantle, head and eight arms. They have no internal or external skeleton which enables them to slip through even the smallest of crevices.

Arms and suckers

With hundreds of suckers along their eight arms, octopuses are able to use their tentacles for tasting, smelling and holding objects. Moreover, the suction cups create an intense vacuum seal that aids in catching prey and clinging onto surfaces.

Ink sac and chromatophores

Octopuses have developed a remarkable defence system which includes both an ink sac that produces a dark fluid and specialized pigment cells, known as chromatophores, for camouflaging. These incredible creatures use their adaptable coloration to blend in with the ocean floor or hide from potential predators.

Intelligence and Behavior

Cognitive abilities

Octopuses are renowned for their remarkable intelligence, problem-solving abilities, and flexibility. They can pick up information through observation, figure out complicated puzzles with ease, and even use tools! All of this reveals the astounding intellectual powers they possess.

Camouflage and mimicry

Octopuses are masters of disguise, allowing them to vanish into their environment. They also possess the remarkable ability to impersonate other creatures such as sea snakes and flounders in order to fool hungry predators.

Escape and defense mechanisms

Not only do octopuses have ink sacs, but they can regrow amputated limbs, jet propel themselves to escape danger, and some species even possess venomous bites as a last line of defence.

Octopus Species and Habitats

Different species

With more than 300 distinct species, octopuses come in all shapes and sizes – from the minuscule Octopus wolfi to the gargantuan pacific octopus (Enteroctopus dofleini).

Global distribution

From shallow coral reefs to the seafloor depths, octopuses traverse a wide-spanning array of marine ecosystems in oceans across the globe such as the Pacific, Atlantic, and Indian Oceans.

How to catch tako?

Octopuses are active hunters, so they can be caught using baited traps or by spearfishing. Tako can also be bought from Japanese markets and specialty fisheries.

Tako as a Culinary Delight

Traditional dishes

Tako is an in-demand component of Japanese meals, regularly appearing as sushi, sashimi or takoyaki. However, the flavour and texture of this octopus delight isn’t limited to its homeland – Korean, Mediterranean and Hawaiian cuisines all have their own distinctive dishes.

What is Takoyaki?

Takoyaki is a popular Japanese snack made with Tako, onions, ginger, and batter. The Tako is diced into small pieces and mixed with the other ingredients before being cooked in special Takoyaki pans. Once cooked, Takoyaki are usually served with mayonnaise, soy sauce, seaweed (nori) flakes, and bonito fish flakes. Takoyaki is a popular street food in Japan and can be found at festivals, markets, and Takoyaki stands.

Preparation and cooking techniques

To ready tako for consumption, the octopus meat must first be softened with tenderizing techniques such as massage, boiling or freezing. You can then cook it in a variety of ways – grilling, frying or simmering – or you can simply enjoy it raw and fresh as sashimi.

How to clean tako?

When preparing Tako for cooking, it is important to remove any sand or dirt from its body. Tako should be washed under running water and then soaked in a mixture of vinegar and water for around 20 minutes before being used in recipes.

Conservation and Ethical Considerations

Population status

Although most octopus populations are not facing endangerment, certain species have been threatened by overfishing, the destruction of their natural habitat and the effects of climate change.

Ethical concerns

As sentient creatures, octopuses have long been the subject of discussion regarding their protection and well-being in culinary as well as scientific contexts. Numerous individuals contend that due to their intelligence, they should be treated with additional consideration concerning humane management and handling. For instance, countries like the UK have added cephalopods into their animal welfare legislation, recognizing their capacity to suffer pain or distress.


From their amazing anatomy and brains to the various environments they inhabit, tako or octopuses are undoubtedly remarkable creatures. As we continue to unravel more of these astonishing sea-dwellers, it is critical that we factor in ethical considerations when interacting with them so as to preserve healthy populations while still upholding their well-being.
