Micro and Macroalgal gut content assessments of two commonest limpets: Cellana radiata and Acmaea sp. disclosed that both species are basically microphagous algal grazers but Cellana radiata also grazes upon the macroalga Ulva sp. Main food items investigated in the gut of these two limpet species were diatoms, although some Cyanobacterial species were also recorded occasionally.
