Lepas anserifera
''Lepas anserifera'' is a species of goose barnacle or stalked barnacle in the family Lepadidae. It lives attached to floating timber, ships' hulls and various sorts of flotsam.〔
==Description==
''Lepas anserifera'' has a shell or capitulum enclosed in six white plates supported by a tough, flexible, orange stalk or peduncle. The capitulum is about long and the stalk a similar length. The limy plates are thick and sculptured and are in close contact with each other. The largest plates, the pair of scuta at the stalk end, are quadrangular with longitudinal furrows and a smooth umbonal area. The pair of terga at the free end are trapezoid and more furrowed than the scutum and the carina in between are wide and forked. The tergal flaps are yellow, giving a coloured rim to the plates in the living animal. The body concealed by these plates consists of a head and thorax with a vestigial abdomen. The head bears the mouthparts consisting of a labrum with fine teeth on the inner margin, a blunt palpus, mandibles and maxillae. The thorax bears three pairs of maxillipeds and cirri with five or six pairs of long feeding appendages. The caudal appendages are curved and pointed which helps distinguish ''Lepas anserifera'' from other species.〔(''Lepas anserifera'' ) Marine Species Identification Portal.
