We compared algae found in the alimentary canal of each species with algae found on tiles placed in the same streams. Algae collected from tiles primarily consisted of diatoms, green algae, and blue-green algae, with diatoms being the dominant taxa at all six of our study sites. Tadpoles of both species consumed mostly diatoms, and the food contents were similar between them. We found high similarities between the algal composition on the tiles and food in the alimentary canals of the tadpoles, suggesting that R. sauteri and B. bankorensis tadpoles are non-selective with respect to the type of algae they ingest.
