摘　　要：During routine chemical analyses of the stalked ibliform barnacle Chaetolepas calcitergum Buckeridge&Newman 2006,peaks of more than 7%(by dry mass)of bromine were detected.Although bromine ions occur in seawater(up to 66 ppm),this level of accumulation,in the soft tissue of the barnacle,is extraordinary.Organic concentration of bromine compounds occurs in a number of invertebrates,such as algae and sponges,but this is the first record of elevated bromine in goose barnacles.The high accumulation of bromine compound(s)is most likely a defense mechanism.The present paper includes a review of the mechanisms deployed by barnacles to repel predators.
