. Three‐weekly transects were done over a 14‐month period at Sundays River Beach, a high energy beach in Algoa Bay, South Africa, to determine the life histories, breeding patterns, and fecundities of three intertidal cirolanid isopods. Eurydice longicornis. Pontogeloides latipes , and Excirolana naialensis. E. longicornis exhibits an annual, multivoltine life history with a more extended breeding period than the other two species. P. latipes and E. natalensis both have biennial. univoltine life histories with lower fecundities than E. longicornis.
