Lepas is a genus of barnacles that belong to the family Lepasidae. These marine crustaceans are commonly found attached to floating objects, such as driftwood, boats, and even whales. They have a distinctive conical shell and can be recognized by their long, feathery appendages called cirri, which they use to filter food from the water. Lepas species are often referred to as "goose barnacles" due to their appearance and the way they attach themselves to surfaces. They thrive in various oceanic environments and play a role in the marine ecosystem by serving as a food source for other animals.
