Genus Lepas is a group of marine crustaceans commonly known as goose barnacles. They attach themselves to floating objects and are often found floating at sea. Other synonyms for the Genus Lepas include pedunculate barnacles, stalked barnacles, and sessile barnacles. However, these names are not always interchangeable with the term goose barnacles, as they refer to different types of barnacles. The Genus Lepas includes more than 20 species that are found throughout the world's oceans. These barnacles are a source of food for various marine animals and have been considered a delicacy in many countries for centuries. Despite their small size, goose barnacles play a vital role in the marine ecosystem.
