The goose barnacle Conchoderma virgatum is a highly opportunistic epibiont, with observations of attachment to a wide range of marine organisms. Attachment to perciform fishes, however, is rarely observed. Observations of Conchoderma-osteichthyan associations in general are also rare in the southern hemisphere, especially in Australian waters. We present the first record of C. virgatum as an epibiont on an ephippid fish (Platax teira). This is also only the second known record of C. virgatum attached to a perciform fish in the Tasman Sea. We also summarize all previous known observations of C. virgatum in association with perciform fishes.
