While on a boat trip to one of the islands on the Ria Formosa the boat’s skipper proudly introduced us to these slimey critters.
Sea cucumbers or “Sea rats” as they are aptly nicknamed by some fishers and divers because of how they move and feed—slowly crawling over the seabed, cleaning up waste and debris like rats rummaging. through scraps on land.
Sea rats? Rats!!!

Despite their name, sea cucumbers are not vegetables—they’re squishy, soft-bodied marine animals that live on the ocean floor.
As you can see from my phototgraphs they have long, tube-like bodies that can look a bit like fat worms or squishy pickles. Most of them crawl slowly across the seabed, cleaning as they go: they eat sand or mud, digest the bits of organic matter inside, and then expel the rest. In doing so, they help recycle nutrients—sort of the ocean’s vacuum cleaners.
Can You Eat Sea Cucumbers?
Apparently, yes. In many parts of the world, especially across Asia, sea cucumbers are considered a delicacy. My stomach is already doing cartwheels just writing this.
They’re eaten fresh, dried, or in soups and stews. The texture is soft with a jelly consistency, and the flavor is mild—people often say it’s more about the sauce or broth it’s cooked in.
They’re also valued in traditional Chinese medicine, believed to support joint and skin health (though evidence for that is mixed).
How to prepare them?
When people prepare them, they usually start by cleaning and boiling the sea cucumber to soften it. Dried ones need to be soaked for days before cooking.
To be honest I don´t feel brave enough to try. —–I will put them in the same ‘YUCK’ box as oysters.
Would you ever try one, or does it sound a bit too adventurous?
Further research
I’ve not seen them on a menu in Portugal or perhaps the name got lost in translation. I asked the question
In Portuguese, sea cucumbers are called “pepinos-do-mar.”
It literally means “cucumbers of the sea.” You’ll sometimes also see local or regional names like “holotúrias” (from their scientific class, Holothuroidea).
So:
- Pepino-do-mar = common everyday name.
- Holotúria = more scientific or formal.
Kind of charming that both languages landed on “cucumber.”

“Could you eat them?”
Nope. I’ve no problem with watching them under the ocean or sea, but the texture alone… not interested.

Oh, in the Yuck Box for me too. At first look at photo I thought it was some kind of vegetable, even so I doubt I would have tried one – and I love vegetables!

I think that *maybe I could eat them. But only if they were already prepared and I hadn’t seen them in there natural state before the meal. They look quite yucky, but I’ve heard they can be good!

I’ve only ever had it a few times in a soup and it’s actually quite good. I don’t think I can eat them raw though, that slime sends chill down my spine.

I got a couple of minutes into the YouTube video about these guys and it was a big “not a chance” for me. I’m usually a pretty adventurous diner, however I “do” draw the line at some things. Many years ago on a visit to New Orleans, I tried raw oysters on the half shell … and that did me in forever, for any kind of oysters or any preparation of them.

I have never tried oysters and never will! I don’t even recall having a prawn. I don’t think any shellfish are for me, plus heard too many stories as a kid of people getting ill from them.

Sorry it ruined what should have been a lovely occasion. It is not great how you cannot tell when you start eating that something is bad so you can immediately stop. Similar happened to me with a bean burger once – think it had been left out and perhaps reheated too many times …

No, no, no! I can eat snails – smothered in garlic butter, of course! But not these critters. They do a marvellous job cleaning up the seabed, so imho they should stay there 😂 Your post left me feeling decidedly queasy, but it definitely had an impact and I learnt something!

First, I LOVE this post! When I produced a cooking series, my Production Manager proudly presented me with a framed, dried Sea Cucumber as a memento, because we did cook with it! The competing Chefs were given it dried, and most re-hydrated it and used it in soups…one did a unique stir fry that included it…I looked up some other uses and because, as you point out, the flavor is so mild, it’s really more a “shock value” ingredient than one that is meant to drive a dish forward…thanks for shiner ghtis I am going to share this story next week – linking back to you!

Hi John,
I would have died if I had been presented with sea cucumber to cook. But at least they were kind and gave you the dried version and not a fresh one. Actually. A fresh one would probably have made more of an impact 😆
