The energy values and ash contents of 15 species of macrofauna found on three exposed sandy beaches on the west coast of South Africa were examined over an 18-month period. A pattern of decreasing energy content with increasing mean body weight was observed. No patterns of seasonal or regional variation were detected in either energy values or ash contents. Ash contents depended on taxonomic group (owing to morphological effects) and the mean size of the species; in the case of the Crustacea increasing with size within a given taxonomic grouping. This is in accordance with the suggestion by Siobodkin & Richman (1961) that energy contents are affected by the extent of storage for adverse conditions.
