Feeding
Species: Uca dussumeri (young)
Mud and sand are free but they contains very limited nutrient, so fiddlers must feed constantly. Fiddler crabs eat the thin coating of detritus on sand grains. They scoop sand to their mouthparts with tiny feeding pincers that are spoon shaped and fringed with hairs. The bristle-like mouthparts scrape the sand grains clean of any edible tidbits.
