| Summay | Fiddler crabs feed at low tide on mudflats in Indonesia and they eat detritus, bacteria and algae. There are often quite a few species feeding together and there is clear niche separation due to their feeding behaviour and morphology. This study compares 3 different species feeding at 2 different heights above the low tide line. The results are analyzed using column charts, means, standard deviation and error bars. There are 2 research questions looking at feeding rates between species and how rates might differ for the same species living at different tidal heights.
