Hello. This is

6 min English from BBC Learning English.

I'm Neil, and I'm Beth. Beth, what do you think about when I say the word

octopus? Well, I know they're intelligence.

They can change color to hide in their surroundings, and of course, they have eight arms.

But I have to admit, I also think about how they taste delicious.

Yeah, I think that too, as do plenty of other people.

Octopus is most commonly eaten in South Korea, spain, portugal and Japan, where they can't get enough of that umami flavor.

Umami is one of the five basic tastes and is a savory flavor.

Until recently, octopus has only been caught in the wild.

But now a Spanish multinational company has announced it will be ready to sell farmed octopus soon, which campaigners have described as ethically and ecologically unjustified.

This is because octopuses are sentient, an adjective describing a thing that experiences feelings like pleasure and pain.

Humans, and many other animals, like pigs, monkeys and birds, are also sentient.

So is it OK to farm octopus when they have been shown to experience feelings?

In this program, will be discussing whether farming octopus can ever be ethical, and as usual, we'll be learning some useful new vocabulary as well.

But 1st, I have a question for you, beth.

Octopuses are known for their ability to problem solve, and when kept in tanks, have been known to escape.

But where did Inky the octopus go when he broke out of his tank at the New Zealand National Aquarium in 2016?

Was it a down a drain into the Pacific Ocean?

B to the tank of a female octopus?

Or see to the aquarium car park?

Hmm, I'll guess he went to the tank of a female octopus.

Okay, beth, I'll reveal the answer later in the program.

In many countries, it's not easy to find octopus in shops, but if plans for farmed octopus go ahead, you're much more likely to see it in the supermarket.

Claire Marshall, who's been reporting on the octopus farm story since 2019, explains why octopuses have not been far before.

And she told BBC World Service program, the food chain, they've got an incredibly complex life cycle, and its scientists have been sort of working feverishly to try to close that life cycle, particularly in Mexico and Japan.

And of sea now Spain, they need life food the larvae.

And also, octopus is incredibly solitary, and it just makes it really hard to manage to basically keep them in captivity at a commercial scale.

Octopuses are difficult to farm because they have a complex life cycle, the series of changes, and animal goes through starting with birth and ending with death.

Unlike traditional farmed animals, like chickens and pigs, who are social animals and can be kept together, octopuses are solitary, meaning they like to live alone.

This makes keeping them in captivity very difficult because of space.

If an animal lives in captivity, it's kept somewhere and not allowed to leave, even if it wants to, like in a zoo.

But it's not only space that is a problem when it comes to pharmon octopus, it's their capacity to feel emotions as well.

Scientific researcher Doctor had The Browning has been studying the sentience of octopuses for a British Government commissioned report.

She shared the report findings with Ruth Alexander, presenter of BBC Radio fool program The Food Chain.

So we wanted to look at whether they had specific kinds of nerve connections, where they had specific kinds of brains, and whether they were capable of performing certain kinds of like trade off behaviors or pain related behaviors, learning behaviors that we thought would correlate with the probability of sentients.

And what we found for octopusses, in particular is they seemed to meet that many of the criteria that we'd laid out.

The scientists found that octopuses do experience feelings because they show typical characteristics of sentient creatures, such as trade off behavior.

Trade Off means giving up one thing in return for another, such as giving up shelter for food.

So it looks like the debates about whether it's an okay to farm and eat octopuses will continue.

Okay, beth, I think it's time I revealed the answer to my question.

I asked you where Inky the octopus went when he escaped his tank at the New Zealand

National Aquarium. And I said it was to the tank of a female octopus.

Well, that was the wrong answer, I'm afraid.

In fact, inky, the octopus was trying to reach the tank of a female but he found a drain instead, which led straight to the Pacific Ocean.

Okay, let's recap the vocabulary we've learned from this program, starting with umami, the flavor octopus has, which can be described as savory and is one of the five basic tastes.

If something is sentient, it experiences feelings such as joy and pain.

Life cycle is the series of changes something goes through from birth to death.

If something is solitary, it likes to live alone.

In captivity means an animal is kept somewhere and is not allowed to leave.

And finally, trade off means to exchange one thing for another.

Goodbye for now. Goodbye 6 min English.
