AW = Wr080, (, ), N = 24, R2 = prey in large quantities (171 items per 200 anemones, and 29 items per 112 ane- mones, respectively). M. senile, however, captured only 16 items per 107 anemones. Coelenteron-content analysis showed that the experimental prey items of A. xan- thogrammica (Table I) and A. elegantissima (Table II) were well within the size range of naturally occurring prey but that the adult brine shrimp were much larger than natural M. senile prey (5 mm vs. mm mean length) (Table III). Prey capture by A. xanthogrammica was proportional to the power of weight, by A. elegantissima to the power of weight, and by M. senile to the power of weight. To compare capture rates, I assumed that naturally occurring prey in the coelenteron contents represented the same feeding period for all anemone sizes. This seems likely because, given the digestive machinery of sea anemones (prey are wrapped in mesenterial filaments which secrete enzymes onto the prey and engulf particles of material into the digestive endodermal layer), large and small anemones probably digest the same prey item in equal time. Number of naturally occurring prey captured by A. xanthogrammica (prey-individual"1 -feed- ing period ') was proportional to the power of weight (Fig. 5). For A. ele- gantissima it was proportional to the power and for M. senile it was propor- tional t
