Percebe Gallego de O Roncudo is a seafood delicacy offered by Marisco 2.0, sourced from the coast of O Roncudo near Corme, in the Spanish region of Galicia. It belongs to the species Pollicipes pollicipes, an edible goose barnacle whose harvesting forms part of the local maritime tradition.

It grows in clusters attached to rocks along the open coast, exposed to powerful waves and well-oxygenated water. It is harvested by hand using a traditional barnacle scraper, a task that requires experience and knowledge of sea conditions.

It is prized for its pronounced sea flavor, with the edible flesh enclosed within the leathery stalk. The seller recommends a simple preparation: boiling for approximately one minute in water with salt and a few bay leaves.
