Abstract

This is the first record of the epizoic barnacle (Octolasmis angulata) on the crab Charybdis feriatus. Prevalence of O. angulata was 85·7% and mean intensity of infestation was 59±64·5 (range 3–239). Prevalence and mean intensity of infestation increased with host size in the range 55–120 mm carapace width. Barnacles occurred most frequently on the gills, anterior branchial chamber wall in the epibranchial space, occasionally on the wall of the branchial chambers beneath the gills and on the scaphognathite within the branchial chambers. Most barnacles were observed on the hypobranchial surface of the gills.
