Goose barnacles (suborder Lepadomorpha) are filter-feeding crustaceans that live attached to hard surfaces of rocks and flotsam in the ocean intertidal zone. They are easily recognisable by their distinctive long and muscular stalk, which is edible and is considered a delicacy in several Mediterranean countries.

Some species of goose barnacles are pelagic and are most frequently found on tidewrack on oceanic coasts. Unlike most other types of barnacles, intertidal goose barnacles depend on water motion rather than the movement of their cirri for feeding, and are therefore found only on exposed or moderately exposed coasts. In Spain and Portugal they are known as percebes and there is a percebes festival in Galicia (on Spain's Atlantic coast) every summer. Every year people are drowned as they try to collect the delicacy from wave-washed coves. Goose barnacles are generally steamed in their shells above stock or seasoned wine and served hot at the table. The outer sheath-like skin is leathery in texture, and is easily removed by pulling the 'claw' and the skin with the a thumbnail at the join. The taste is said by some to be similar to crab claws, although the texture is very different, something more akin to snails, soft and chewy, and moist, unlike crab. They are also particularly favoured in Donostia in the Basque Country.

In the days before it was realised that birds migrate, it was thought that Barnacle Geese, Branta leucopsis, developed from this crustacean, since they were never seen to nest in temperate Europe, hence the scientific and English names. The confusion was prompted by the similarities in colour and shape. Because they were often found on driftwood, it was assumed that the barnacles were attached to branches before they fell in the water. The Welsh monk Giraldus Cambrensis claimed to have seen goose barnacles in the process of turning into barnacle geese in the twelfth century.

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.
