NOAA Photo Library Image - expl2187

Close-up imagery showing barnacles covering sulphur structures on Kawio Barat volcano. Their tentacles, or 'cirri', extended like blooming flowers, then folded back into the shell. The white fluff on the cirri are filaments of bacteria that grow in the passing vent water. The barnacles hold them out to improve growth then, apparently, withdraw to 'lick their fingers'.
