General Description

A stalked barnacle with five side plates. Plates finely ridged and white with orange outline. Stalk shorter than length of plates. Plates up to 4 cm long and 25 mm wide, stalk up to 2 cm long.


These barnacles attach to floating objects such as drift wood. Colonies of multiple barnacles can wash ashore, still attached to their floating home. The stranded colony may survive a short time on the beach and the cirri can be seen moving but it will not live long in this environment.
