Abstract: The guts of frog tadpoles in Llysdinam Pond, 1 983, frequently contained detritus (partially decomposed macrophyte tissue) and other items associated with the pond's sediment (the tests of rhizopod protozoa, pollen grains, fungi), suggesting that the frog tadpoles fed directly on the sediment. The guts of toad tadpoles from Llysdinam, 1 984, however, contained high frequencies of rotifers (Keratella) and motile algae (Dinophyceae) and little detritus, suggesting that the toad tadpoles fed mainly in m id-water. Evidence of both m id-water and sediment feeding was observed in samples of toad tadpoles from other ponds. Samples of frog tadpoles from other ponds, however, showed only the sediment feeding mode.
