Goose Barnacles

Goose barnacles thrive on rocks, ships, ropes, and other floating debris at sea. They've even been spotted on a spaceship fragment that washed ashore in the Scilly Isles! They feature a long fleshy stem that resembles a black neck and are also known as gooseneck barnacles. The barnacle's main body is housed in a chalky white shell at the top of the stem, or peduncle.

These unusual crustaceans, often known as stalked barnacles, reside on rocks and flotsam. Free-diving or at low tide are the only ways to gather gooseneck barnacles.

As a result, they are some of the most costly seafood on the planet. Goose barnacles are found in Australia, Cape Verde, France, Morocco, and Spain, and are native to the Eastern Atlantic. Galicia, Spain, produces the most valuable geese barnacles.

Goose barnacles can cost up to $125 per pound. Gooseneck barnacles have a salty flavor that is finest washed down with a glass of vinho verde wine!
