Description: | Barnacles are highly specialised crustaceans that have a carapace (skeleton) composed of six hard plates. The plates form a round body chamber known as a capitulum. In Balanus, opercular valves like the specimen shown are used to close the chamber and completely protect the animal's soft body. Barnacles live in high-energy intertidal zones (the area between high and low tide) cemented to rocky seabeds and shells where they feed on tiny plant and animal particles that they filter out of the sea water. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
