I Love Mud
Species: Uca crassipes
The body of fiddler crab can absorb the organic substance in the mud. Mangrove forest is an infertile land to most plants and animals but a paradise to fiddler crabs. The crabs make burrows up to 60 cm (23 inches) deep in the muddy substrate to which they retreat during high tides. When the tide is out, fiddler crabs tirelessly scurry sideways along the beach as they comb the sands for food.
