A lot of goose barnacles were attached to a buoy that had been washed up on the beach in front of our marine biological station (see momo030428ar01b "A polychaete worm Amphinome found on wrack".). Barnacles were brought back to the laboratory and their foraging behavior in flowing water was observed. Animals of the order Cirripedia (barnacles and goose barnacles) are often mistaken for shellfish, but they actually are members of Crustaceans (shrimps, lobsters, crabs etc.). A goose barnacle has a head region enclosed in white plates and a flexible stalk. What is inside the head is something like an up-side-down shrimp. A barnacle opens the plates and extends their feathery limbs called cirri into the water. It extends and contracts the cirri and removes suspended material from the surrounding water. This type of foraging is characteristic of Cirripedia. (translated by Asoh)
