Goose Barnacle (Percebes)
Pollicipes pollicipesA shellfish that clings to the wave-battered rocky coasts of Spain and Portugal, known for its dark, rough stalk that resembles a claw. It is expensive and considered a delicacy because it is difficult and dangerous to harvest.
What Are Goose Barnacles (Percebes)?
Percebes (Spanish for “goose barnacles”) are a type of shellfish (Pollicipes pollicipes) that clings tightly to the wave-battered, rocky Atlantic coasts of the Iberian Peninsula (Spain and Portugal). They are not closely related to crayfish; they are closer to a mollusk-like shellfish attached to rocks.
They have a dark, rough, flexible “stalk” and a small shelled “claw” at the end, which is why they are compared to “dinosaur claws” in some cultures. Because they grow only on rocks hit by the strongest waves, harvesting them is both difficult and dangerous.
Nutritional Value of Goose Barnacles
Boiled goose barnacles provide about 80 kcal per 100 g; they are high in protein and, because they live in seawater, also contain natural sodium. These values are approximate.
How Should Goose Barnacles Be Eaten?
As a high-protein seafood, goose barnacles can be considered part of a balanced diet; because of their natural saltiness, serve them without adding salt.
This is general information; goose barnacles are a food, not a medical treatment.
How to Choose Goose Barnacles
Good goose barnacles are live and fresh (the stalk contracts slightly when touched), dark and glossy, and smell of the sea. Avoid any with an off smell or a limp, lifeless stalk.
- They should be live and fresh, with a slight reaction to touch
- Their color should be dark and glossy
- They should have a fresh, briny smell, not an off odor
How to Store Goose Barnacles
If bought live, goose barnacles should be eaten within 1 day when refrigerated; they are among the most perishable seafood.
Using Goose Barnacles in the Kitchen
Goose barnacles are most often briefly boiled in salted seawater for a few minutes and served plain; additional spices or sauces are generally not used, so their naturally salty, briny flavor stands out.
How to Eat Goose Barnacles
After boiling, hold one by hand, pull off the outer skin, and suck or pull out the soft meat inside; eat it directly.
