Abstract: 1. The mesofauna associated with the red algae R. affine and G. papillata, in the lower midtide zone, includes, in order of abundance: Nematoda, Copepoda, Barleeia haliotiphila, Tricolia pulloides, Lasaea cistula, mites, Polychaeta, Ostracoda, Nemertea, Isopoda, and Amphipoda. 2. Although the same taxonomic groups of small animals are present in R. affine and G. papillata, mesofaunal populations per unit area of R. affine are nearly twice those found in G. papillata for the more abundant taxa. 3. Populations of mesobiota in both plants appear to vary most directly with the amount of sediment present. 4. No size differences exist between mesobiota in R. affine and G. papillata.
