Common name: Goose Barnacles

Lepas is a genus of barnacles in the family Lepadidae, commonly known as goose or stalked barnacles. These filter-feeding crustaceans are notable for their long, fleshy stalks that attach to floating debris or ships' hulls. In the aquarium, they can be fascinating additions, especially in larger systems where they can be observed filtering food from the water column. They require strong water movement to mimic their natural environment and a steady supply of planktonic food to thrive.
