Cirripedes are one of the major groups of fouling organism in the marine environment. The cyprid can, before a permanent attachment, actively explore and walk on the substratum using its antennules in a bipedal fashion without leaving the surface. Studying the structure of the cyprid antennule is therefore important for understanding the events that culminate in biofouling by barnacles. There are at present no complete, standardised accounts of the structure of the cyprid antennules in thoracican barnacles, and moreover, the existing accounts vary in their use of terminology. This article describes the cyprid antennule of the barnacle Megabalanus rosa. This barnacle species is common in E Asia, and the cyprids have previously been used in several biofouling studies. All externally visible setae on the antennules have been mapped; these comprise both chemosensors with a terminal pore, a putative aesthetasc-like …
