Two beaches in Algoa Bay. South Africa. have been found to support a relatively rich and varied meiofauna. Highest numbers were recorded at HW on the sheltered beach (2 250/10 cm� ) and the lowest numbers at LW on the same beach (60/10 cm� ). On the exposed beach numbers were more uniform but were highest between MW and LW. Macrofauna was richer on the exposed beach, mainly due to the sand mussel, Donax serra. Production estimates based on standing crop indicated that the meiofauna may account for 55 per cent and 28 per cent of the total secondary production on the sheltered and exposed beaches respectively.
