Goose barnacles feeding C017 / 8440
Goose barnacles (Lepas anatifera) feeding underwater. These cirripedian crustaceans attach themselves to boats and driftwood. Their long stalk is derived from the elongated head and cements the barnacle to its host surface. The rest of the body is a carapace or mantle of five calcified plates. When the valves of the mantle open, the thoracic limbs (black), hang out. The limbs, which are covered in fine bristles (cirri), are thrust in and out allowing the cirri to filter out small plankton which are then conveyed to its mouth

EDITORS COMMENTS
This print captures the mesmerizing sight of Goose barnacles (Lepas anatifera) feeding underwater. These unique cirripedian crustaceans have a fascinating way of survival as they attach themselves to boats and driftwood using their long stalk, which is derived from their elongated head. The rest of their body consists of a carapace or mantle made up of five calcified plates. In this image, we can see the valves of the mantle opening, revealing the black thoracic limbs that hang out. These limbs are covered in fine bristles called cirri, which play a crucial role in filtering out small plankton from the water. The filtered plankton is then conveyed to its mouth for nourishment. The coastal setting adds to the charm of this photograph, showcasing these barnacles thriving in their natural habitat within the tidal zone. Their presence not only highlights the diverse marine fauna but also emphasizes their active role as filter feeders. As we delve into marine biology and explore the wonders beneath our oceans, images like these remind us of nature's intricate beauty and complexity. This stunning portrayal by DR KEITH WHEELER/SCIENCE PHOTO LIBRARY invites us to appreciate and learn more about these incredible creatures known as goose barnacles or gooseneck barnacles (lepas anatifera).
