Abstract

Direct observations of sex change were made on Patella vulgata, which has long been considered a protandrous hermaphrodite based on indirect methods. Thirty per cent of the male limpets that were marked during the spawning season in 2003 were female when they were re-examined during the spawning season in 2004. This confirms that protandry does occur within the superfamily Patellidae.
