Abstract Abundance of macro‐algae in the mid‐littoral zone on a Victorian intertidal rocky shore varied seasonally, algae being rare in Summer and common in Winter and Spring. Field experiments demonstrated that, of two species of grazing limpets (Cellana tramoserica and Siphonana diemenensis), only Siphonaria had a major effect on the abundance of foliose algae (e.g. Scytopsiphon lomeniarid) and neither species had a great effect on the encrusting algae (Ralfsia spp.). There was no evidence of competition for food between the two species of limpets, in contrast with results found for similar species in New South Wales.
