The family Lepadidae is a group of sessile, barnacle-like crustaceans that attach themselves to hard substrates and filter feed on planktonic organisms. They are commonly known as goose barnacles, and although they are often associated with ships and wooden debris, they can also be found on rocks and other marine structures. Synonyms for the family Lepadidae include the genera Lepas, Conchoderma, Dosima, and Austrolepas. These species can be distinguished by their shell morphology, number of cirri, and other anatomical features. Despite their relatively simple appearance, Lepadidae barnacles play an important role in marine ecosystems, serving as a food source for many fish and invertebrates.
